Daf Yomi for Women - Hadran

Study Guide The Mishna, as in Chapter 2 (Zevachim 29b), outlines various scenarios in which a thought can, or cannot, render a sacrifice pigul, thereby making consumption of the meat punishable/not punishable by karet. Rabbi Yehuda disagrees with one of the rulings and maintains that if melika (the ritual slaughter of a bird) was performed with the intent to offer the blood beyond its designated time, and the blood was then squeezed with the intent to burn the flesh outside the Azara (Temple courtyard), the offering would be considered pigul. This is because, although the sacrifice was already disqualified for other reasons, the disqualification due to improper intent regarding time occurred first. A braita examines the verses concerning the bird burnt offering and derives several halakhot specific to this sacrifice: One who volunteers to bring this type of offering may bring only one bird. Melika must be performed by a kohen. Melika is not performed with a knife. Melika is performed at the top of the altar. Melika is done on the back of the bird's neck. The bird's head must be severed. All the blood must be squeezed out - none may remain. The blood is squeezed onto the upper part of the altar wall. There is a debate whether melika and the squeezing of the blood are performed on the sovev (the ledge surrounding the altar) or at its top. Another braita presents differing opinions regarding which parts of the bird are cast onto the beit hadeshen (the ash heap) and how those parts are removed. The bird is split in half - this is done by hand, as derived from a verse in Judges concerning Shimshon. Rabbi Elazar ben Rabbi Shimon disagrees with the tanna of our Mishna regarding a bird sin offering in which the kohen severs the head: is the offering thereby disqualified or not? Three interpretations are offered to explain the basis of their disagreement.  

Three actions were performed at the bottom of the altar on the southwest side, as derived from verses in the Torah. The bird burnt offering was usually brought on the southeast side so that the kohen could be close to the beit hadeshen, where parts of the bird were discarded. Three actions were performed at the top of the altar on the southwest side, and the kohen performing the action would go directly there instead of walking around the altar entirely. The reason was to avoid damaging the items from the smoke rising at the top of the altar. The Mishna describes in detail how the bird sin offering was performed. A braita provides a source explaining why the blood of this offering was placed on the lower part of the altar and not the upper part, as is done with the animal sin offering and the bird burnt offering. Two different versions of how to perform melika are presented—one in the name of Rav and one from a braita. It was known to be one of the more difficult actions the kohen had to perform. Performing the kmitza on the meal offering and the chafina with the incense on Yom Kippur were also known to be challenging. The Mishna describes in detail how the bird burnt offering was performed. Some elements were similar to the sin offering, yet many differed. For example, the head was not severed in the sin offering, but was in the burnt offering. The entire bird was eaten by the kohanim in the sin offering, whereas the burnt offering was completely burned, aside from the parts tossed into the beit hadeshen (crop, feathers, and innards). Other differences include the laws regarding sacrificing with intent for the wrong type of offering. The sin offering is disqualified, as with animal offerings, while the burnt offering is not. Regular laws of pigul apply to both.

All ramps in the Temple had a slope of three cubits in length for every one cubit of height, except for the ramp of the altar, which had a gentler incline of three and five-ninths cubits. This was to accommodate the kohanim, who had to carry the animal body parts up to the top of the altar. The kmitza—a handful taken from the meal offering—could be performed anywhere within the Azara (Temple courtyard). The remainder of the offering was eaten by male kohanim, could be prepared in any manner, and was permitted to be eaten only on that day and the following night until midnight. Rabbi Elazar taught that if the kmitza was taken in the Heichal (Sanctuary), it was still valid. He compared it to the bowls of frankincense, since both are referred to with the term azkarata, and the frankincense is brought from inside the Sanctuary and burned outside. Rabbi Yirmia raised a challenge from a braita that seemed to imply the kmitza must be performed where the owner presents the offering—i.e., not in the Sanctuary, which is restricted to kohanim. However, two interpretations of that braita are offered, the first of which is rejected. Both explanations ultimately show that the braita was not intended to restrict the location of the kmitza, but rather to broaden it. Rabbi Yochanan ruled that peace offerings may be slaughtered in the Sanctuary. His reasoning was that since slaughtering may be done outside the Ohel Moed, it stands to reason that it may also be done inside. If the secondary location is valid, then certainly the primary one should be. A difficulty is raised from a braita concerning eating in the Sanctuary, which is prohibited, if not for a verse permitting it in unique circumstances. To resolve this, a distinction is made: slaughtering is a sacrificial rite, whereas eating is not. The bird sin offering is ideally performed on the lower half of the altar at the southwest corner, though it may be offered anywhere on the altar. Six actions were performed at the southwest corner—three on the lower half and three on the upper half of the altar. On the lower half: the bird sin offering, bringing the meal offering to the altar for kmitza, and pouring the remainder of the blood into the yesod (base). On the upper half: pouring the wine and water libations, and offering the bird burnt offering. When ascending the altar, people would typically go up the ramp on the right side, turn right at the top, begin at the southeast corner, and circle counter-clockwise around the altar before descending via the left side of the ramp. However, for the three actions performed on the upper southwest corner, they would ascend via the left side of the ramp to reach that spot directly, then turn around and descend from there after completing the task. The bird sin offering is brought at the southwest corner, a location derived from the placement of the meal offering. The meal offering's placement is itself derived from the verse in Vayikra 6:7.  

Rav Yosef offers two additional explanations for why the altar in the Second Temple was constructed larger than the altar in the First Temple. When the Second Temple was built, how did they determine the correct location for the altar? Three explanations are brought. Which components of the altar are essential for carrying out sacrificial rites? The ramp of the altar was positioned on its southern side, measuring sixteen cubits in width and thirty-two cubits in length. Rav Huna cites a source to confirm that the ramp was indeed located in the south. A braita presents an alternative source from a statement by Rabbi Yehuda. There was a space between the altar and the ramp - the origin and function of this gap are clarified. If the ramp was thirty-two cubits long and the altar itself also measured thirty-two cubits in length, how does this align with the Mishna in Midot 5:2, which states that the total length was sixty-two cubits?

Sources Can kodshim kalim be eaten when there is no altar? Abaye proved from a braita of Rabbi Yishmael that they cannot be eaten. Rabbi Yirmia raised a difficulty against Abaye from a contradiction between braitot, resolving it in a way that one would conclude that kodshim kalim could be eaten even without an altar. However, Ravina provides an alternative resolution to the contradiction, and the Gemara brings another. Rav Huna says in the name of Rav that the altar in the Tabernacle of Shilo was made of stone. However, a difficulty is raised against this from a braita that explains that the fire of Moshe's copper altar continued until the time of Shlomo. They resolve it by saying that Rav Huna held by a different tannaitic opinion. Alternatively, one can explain that the fire could have still been on Moshe's altar, even though they were using the stone altar. If so, what was the fire used for? The Gemara suggests two possible answers. A Mishna is brought which says that the altar in the time of the Second Temple was expanded to be larger than the one in the First Temple, from 28x28 cubits to 32x32. Why? Rav Yosef suggests it was expanded as they needed more space. Ravin explained it based on a Mishna in Middot that described the addition of the shitin, two holes that were added for the libations.

In Zevachim 59, a difficulty was raised against Rav's position that a sacrifice slaughtered while the altar was damaged is disqualified. The contradiction came from a statement of Rav that incense could be burned even when the altar was removed. It was resolved by suggesting that just as Rava explained, Rabbi Yehuda distinguished between blood and burning (and required the altar for blood), so too Rav distinguished between blood and burning the incense (and required the altar to be complete for slaughtering and sprinkling the blood). Where did Rava make that statement? A lengthy argument between Rabbi Yehuda and Rabbi Yosi is brought to provide background. Then a proof is offered for Rava's understanding of Rabbi Yehuda, based on Rabbi Yehuda's suggestion regarding the blood from the Paschal sacrifices that spilled on the floor, but the proof is rejected. Rabbi Elazar brings a source to derive the requirement for the altar to be complete  to permit eating the remains of the meal offerings and other food of kodashim kodashim. Is a complete altar required for eating kodashim kalim? Abaye brings a braita of Rabbi Yishmael proving that the second tithe cannot be eaten in Jerusalem when there is no Temple. He first attempts to derive it from the firstborn by logical inference, but then derives it from a juxtaposition (heikesh). Abaye's explanation of Rabbi Yishmael leads to the understanding that kodashim kalim cannot be eaten when there is no altar. Rabbi Yirmia vehemently disagrees with Abaye, calling him a 'stupid Babylonian,' due to a contradiction between two braitot, which he resolves by differentiating between kodshai kodashim and kodashim kalim regarding this law.  

Diagrams Study Guide Rav Shravia raises a second difficulty against Rabbi Zeira's proof for Rabbi Yochanan's statement that Rabbi Yosi held the altar was completely in the north from the Mishna in Tamid 29a. He suggests that perhaps it was not Rabbi Yosi's opinion, but rather Rabbi Yosi the Galilean, who held that the altar was in the north. He cites a different braita relating to the placement of the basin (kiyur) and explains why that proves Rabbi Yosi the Galilean must have held that the altar was completely in the north. Rav and Rabbi Yochanan debate the status of sanctified animals that were designated, and then the altar becomes broken. A verse is brought as the source for Rav's position. Two difficulties are raised against Rav's view—one from a braita and one from a statement Rav himself made—and both are resolved. In resolving the second difficulty, the Gemara mentions a position of Rabbi Yehuda. It then explores this opinion in the context of a debate between Rabbi Yehuda and Rabbi Yosi regarding the size and height of the altar in the time of Moshe.

Diagrams If kodshei kodashim were slaughtered on top of the altar, is that considered a valid slaughter? Rabbi Yosi maintains that it is as if they were slaughtered in the north, and therefore valid. In contrast, Rabbi Yosi b'Rabbi Yehuda holds that it is only valid if performed on the northern half of the altar. Rav Asi cites Rabbi Yochanan, who explains that Rabbi Yosi viewed the altar as entirely situated in the north. Rav Asi assumes that this was derived from our Mishna, where Rabbi Yosi permits slaughtering on the altar. He further clarifies that when Rabbi Yosi stated, "It is as if it is in the north," he meant to emphasize that although the requirement to slaughter kodshei kodashim is "on the side of the altar," slaughtering on top of the altar is also valid. Rabbi Zeira challenges Rav Asi's interpretation by applying the same connection to Rabbi Yosi b'Rabbi Yehuda's position, that he must hold the altar is situated half in the north and half in the south, and introducing another statement from Rav Asi in the name of Rabbi Yochanan, which contradicts that. The second statement of Rabbi Yochanan is that, according to Rabbi Yosi b'Rabbi Yehuda, if one slaughtered on the ground under where the altar stands, it is invalid. Rav Asi responds by explaining that both Rabbi Yosi and Rabbi Yosi b'Rabbi Yehuda derived their views from a verse in the Torah, and it does not hinge on the location of the altar. The verse is Shemot 20:21: "And you shall slaughter on it (the altar) your burnt and peace offerings." The debate centers on whether the verse states that both burnt and peace offerings may be slaughtered anywhere on the altar, or that burnt offerings must be slaughtered on one half (the north) and peace offerings on the other. Rav Acha of Difti asks Ravina to clarify the meaning of Rabbi Yochanan's statement that slaughtering on the ground where the altar stands is invalid. How can one slaughter on the ground where the altar is standing? Rabbi Zeira returns to the original statement of Rabbi Yochanan—that Rabbi Yosi held the altar was entirely in the north—and seeks a source for this in a Mishna. He cites a Mishna in Tamid 29a, which refers to the location of the ma'aracha hashniya, the second arrangement of wood on the altar, as being in the southwest corner, four cubits toward the north. Rabbi Yosi explained the need for this to be situated opposite the exit of the Sanctuary. Rabbi Zeira argues that the arrangement needed to be opposite the exit of the Sanctuary and four cubits north of the southwest corner, which can only be reconciled with Rabbi Yosi's position that the altar was entirely in the north. However, Rav Ada bar Ahava counters Rabbi Zeira's proof by suggesting that the Mishna can be understood according to Rabbi Yehuda, who held that the altar was situated half in the north and half in the south, centered in the room.

Study Guide The bloods of the firstborn, maaser, and Pesach are only sprinkled once on the altar. This is derived from the fact that the word "saviv"-"around" the altar - appears in the context of the burnt, sin, and guilt offerings. One cannot learn from those cases to others, as details that appear two or three times cannot be used to establish a paradigm for a different case. Rabbi Tarfon taught that the firstborn can be eaten for two days and one night, as it is similar to the peace offering. Rabbi Yosi Hagelili, on his first day in the Beit Midrash in Yavne, raised several difficulties with this comparison and likened it to a guilt and sin offering, which are eaten only for a day and night. When Rabbi Tarfon could no longer respond to the questioning, he left, and Rabbi Akiva took his place and said that in Vayikra 18:18, where the firstborn is compared to the thigh and breast given to the kohen, this is a juxtaposition between the firstborn and the peace offering. Rabbi Yosi Hagellil responded that also the thigh and breast are given to the kohen in a thanksgiving offering which is eaten only for a day and night. Therefore, perhaps the comparison should be made to the thanksgiving offering instead. Rabbi Akiva was convinced by Rabbi Yosi that the comparison should be to the thanksgiving offering, but he found other words in the verse from which to derive an additional day. When Rabbi Yishmael heard about this, he engaged in a lengthy debate with Rabbi Akiva regarding his change of position—that the comparison is to the thanksgiving offering. Rabbi Yishmael argued that the law of the thigh and breast in the thanksgiving offering is derived by juxtaposition (heikesh), and the law about the firstborn is derived from the thigh and breast by juxtaposition, and one cannot derive a law from a juxtaposition on a juxtaposition. However, the Gemara explains that this juxtaposition is not typical: while the law of the thigh and breast is derived by juxtaposition, the time limitation is stated directly. The debate between Rabbi Akiva and Rabbi Yishmael centers on whether a law derived partially by juxtaposition and partially stated explicitly can serve as the basis for a juxtaposition to another law. The Gemara raises two difficulties with Rabbi Yishmael's position—one regarding the number of times the kohen gadol must sprinkle the blood of the bull and goat in the Sanctuary (Heichal) on Yom Kippur, and one regarding the amount of flour required for the loaves of matza that accompany the thanksgiving offering. Each of these laws is derived by means of a juxtaposition on a juxtaposition, along with something explicitly stated or derived by a gezeira shava. Each difficulty is resolved. The Mishna stated that the Pesach may be eaten only until midnight. This is the opinion of Rabbi Elazar ben Azaria, but Rabbi Akiva permits it until dawn. Each derives their opinion from a different verse.

Study Guide Today's daf is sponsored by Judy and Jerel Shapiro for the marriage today of their son Oren Shapiro to Fay Gamliel of Toronto. "Mazal tov and may they build a Bayit Ne'eman b'Yisrael, and a bayit filled with love and peace!" Today's daf is sponsored by Beth Kissileff in loving memory of the 11 precious souls killed on the 18 of Cheshvan at Dor Hadash, New Light and Tree of Life in Pittsburgh. Joyce Fienberg, Dr Richard Gottfried, Rose Mallinger, Dr. Jerry Rabinowitz, Cecil Rosenthal, David Rosenthal, Bernice Simon, Sylvan Simon, Daniel Stein, Melvin Wax, and Irving Younger. And in honor of the Daf Yomi Pittsburgh group under the leadership of Rabbi Amy Bardack and Eric Lidji. What is the size of the Temple courtyard, the Azara? These boundaries are important for three laws that are specifically done in the azara only - kohanim eat kodshai kodashim, slaughtering kodshim kalim takes place there, and one is punished by karet for entering while impure. Rav Nachman's father specified the boundaries. There was an assumption that he was trying to exclude a particular space by demarcating the exact size. They explain that he must have been excluding the chambers that open into the Azara but are partially outside the Azara boundaries. A difficulty is raised from a Mishna that designates them as sanctified. But it is resolved by explaining that the Mishna was referring to a rabbinic definition, but by Torah law, they are not considered the Azara. Two other sources seem to contradict this explanation, but are resolved.   Rav Avudimi explained the source that the blood is disqualified if not brought on the altar before sunset of the day of the slaughtering. Rabbi Yochanan and Chizkiya disagree about the status of the meat of a peace offering on the night after the second day, both for laws of pigul and notar. Comparisons are made between the meat of the sacrifices that can be eaten for one day and those that can be eaten for two days – explaining the source of the differences between the two regarding the night of the second day. A firstborn, maaser and Pesach are kodshai kalim and have similar laws. However, certain issues surrounding eating them are different – who can eat them, how the meat is prepared, and for how long they can be eaten.   

Today's daf is sponsored by Diana Bloom in loving memory of her Zayde, Ignacio (Israel) Marmurek, on his 42nd yahrzeit. "A pillar of the Jewish community of Buenos Aires, an ardent Zionist, a loving family man, I am proud to be his granddaughter, and he is missed." Communal peace offerings and guilt offerings have the same requirements. The derivation that communal peace offerings are slaughtered in the North is initially brought from a verse in Vayikra 23:19–20, but this is rejected because it relies on a juxtaposition built upon another juxtaposition - deriving communal peace offerings from sin offerings, which themselves are derived from burnt offerings. Instead, Bamidbar 10:10 presents a direct juxtaposition between communal peace offerings and burnt offerings, making it a stronger source. This raises two questions: why are communal peace offerings juxtaposed to sin offerings in the first verse, and why, in the verse regarding the ram offering of the nazir, is the peace offering juxtaposed with both the sin and burnt offering? One answer is given for the first question, and two possible answers are offered for the second. The Mishna introduces kodshim kalim, sacrifices with a lower level of sanctity. These may be slaughtered anywhere within the Azara and eaten by the owner anywhere in Jerusalem. The first examples cited are the thanksgiving offering (toda) and the peace offering (ram) of the nazir, as they share the same requirements and must be consumed within one day and one night. What is the source that kodshim kalim must be eaten in Jerusalem? Abaye and Rava each derive it differently from Vayikra 10:14. However, Abaye's interpretation is preferred due to a difficulty found in Rava's approach. Regular peace offerings may be eaten over two days and the intervening night. The Gemara cites three verses concerning peace offerings where slaughtering is mentioned, and derives a distinct law from each one—including the rule that they may be slaughtered anywhere in the Azara. Rabbi Eliezer and the first tanna disagree on how these verses should be interpreted and what halakhot can be extracted from them. One of the laws derived from these verses is that the door to the Sanctuary (Heichal) must be open when peace offerings are slaughtered. The Gemara proceeds to analyze the scope and implications of this requirement.

Rav and Levi disagree about whether there was truly no base on the south and east sides of the altar, or whether a base existed but the blood could not be poured there. Various sources are cited to challenge both opinions, and each difficulty is addressed and resolved. One of the sources provides a detailed description of how the altar was constructed. Rava, based on a drasha from a verse in Shmuel I 19:19, explains how David and Shmuel determined that the Temple would be built specifically in the territory of Binyamin and precisely at that location—not elsewhere. Although Ein Eitam was actually higher in elevation, two reasons are given for why that site was ultimately rejected.  

Public and individual sin offerings are categorized as kodshei kodashim. Public offerings include the goat offerings on Rosh Chodesh and the holidays. They are slaughtered and blood is accepted in the North of the Azara. The blood is sprinkled on the top of the altar. The kohen goes onto the sovev, a ledge of the altar, one cubit wide and five cubits off the ground that extends across the length of the altar. From there, he walks around the altar, placing the blood, using his finger, at the top of the altar near the horns. The remainder of the blood is then spilled at the base of the altar, and the meat can be prepared in all manners, and is eaten by male kohanim for that day and night, until midnight. Rabbi Elazar b'Rabbi Shimon holds that the blood was placed on the horns, while Rebbi holds that the blood just needs to be placed above the red line at the mid-height of the altar (chut hasikra). Within Rebbi's opinion, there is a debate between Rabbi Yochanan and Rabbi Elazar whether it needs to be placed on the edge of the corner or can it be up to a cubit away from the corner. Even though a braita clearly states "the edge of the corner," it is possible that is only ideally, but a cubit away would be sufficient as well. Rabbi Elazar b'Rabbi Shimon agrees with Rebbi regarding the blood of a bird burnt offering, which can be done anywhere above the red line, but distinguishes between that and the sin offering of an animal as the Torah specified kranot, horns. The Gemara brings a source for Rebbi's opinion from Yechezkel 43:15 and a source for the red line from Shmot 27:5. There is a debate regarding the placement of the remainder of the blood on the base of the altar – some say both were on the Western part of the base, some say both were on the Southern part and some say the inner ones were poured on the Western part, while the outer ones were placed on the Southern part. What is the basis for the different opinions? The burnt offering is slaughtered in the North and blood is collected in the North. The blood is placed on two corners, but covers all four sides. Rav and Shmuel, based on a tannaitic debate, disagree about whether the kohen throws the blood twice in each corner to get on both sides or in one throw reaching both sides. The blood was placed only from two corners, as one of the corners does not have a yesod, base, underneath and the blood of the burnt offering needs to be placed on the altar where there is a base underneath, as derived from verses earlier in the Gemara. Why was there no base on the East and South sides? Since that area was specifically part of Yehuda's territory, and the rest of the altar was in Binyamin's territory, they did not extend the base there, as Binyamin was promised that the altar would be in his territory.  

The braita in Zevachim 51 extrapolates from the third mention (by the nasi) of the base of the altar that for all sacrifices on the outer altar the remainder of the blood is poured on the base, the yesod. The braita then raises a question: perhaps the extrapolation should be different — that the sprinkling of sacrificial blood on the outer altar must be performed only on the sides where there is a base, i.e., not on the southeast corner, since the base did not extend there. A difficulty on that suggestion is drawn from the verse's wording. The verse states "to the base of the altar of the olah," which suggests relevance to all sacrifices on the outer altar rather than only to the olah. But the sin offering, which is placed on the outer altar, is positioned on all four corners and not limited to the three corners where there is a base. If the verse had intended the latter ruling, it should have been phrased "to the base of the olah," referring specifically to the burnt offering where that limitation would apply. The Gemara resolves this difficulty by explaining the unique inclusion of the word "altar" in the verse: it teaches that when blood is spilled on the base, it must be spilled on the roof of the base (top flat surface) and not on the wall of the base. With this reading, the subsequent lines of the braita, where Rabbi Yishmael and Rabbi Akiva each say the law could have been derived by a kal va'chomer are reread including mention of the roof of the base. Rabbi Yishmael and Rabbi Akiva appear to assert the same logical argument using slightly different wording. Rav Ada bar Ahava and Rav Papa propose possible distinctions between their positions. Rav Ada argues that because Rabbi Akiva used more extended language about the remainder of the blood, that it "does not atone" and "does not come for atonement purposes," Rabbi Akiva must regard pouring the remainder as nonessential. Rabbi Yishmael, having said only "it doesn't atone," must hold that pouring the remainder is essential. Rav Papa rejects this reading, maintaining that no one posits an obligation to pour the remainder of the blood. He narrows the difference between Rabbi Yishmael and Rabbi Akiva to the specific case of the bird sin offering: whether mitzui, squeezing out the remainder of the blood and placing it directly on the wall of the altar while squeezing, is essential. Rav Papa understands Rabbi Yishmael to require mitzui, while Rabbi Akiva does not. A braita is then cited to support Rav Papa, showing that Rabbi Yishmael holds pouring the remainder is not essential. A difficulty is raised against Rav Papa's position, but the Gemara resolves it. Rami bar Hama introduces a tana who maintains that for sin offerings whose blood is placed on the inner altar, pouring the remainder of the blood on the base of the altar is essential; Rava, however, rejects this understanding of the braita and its conclusion. Rabbi Yochanan and Rabbi Yehoshua ben Levi dispute whether Rabbi Yehuda and Rabbi Akiva actually differ on the question of whether the remainder of the blood for inner sin offerings is essential.    

Study Guide After suggesting that one can learn from Rabbi Meir's opinion about melika of a bird that is a treifa, that one can learn a binyan av from a kal va'chomer in kodashim, sacrificial items, the Gemara rejects this explanation because it is derived from chulin, not kodashim. Can one derive a law through a binyan av and then use another method of hermeneutics to derive something else? The Gemara only suggests an answer for a binyan av on a binyan av, but that answer is rejected since the method of derivation in the braita does not make sense. It must be derived from a verse in the Torah, Vayikra 2:6, and the braita is just being used as an asmachta. The remainder of the blood of the inner offerings is poured on the base of the altar on the western side. This is derived from Vayikra 4:7 where it states, "opposite the entrance to Ohel Moed," which refers to the exit of the sanctuary, which is by the western side of the altar. In Vayikra chapter 4, the phrase "pour on the base of the altar" is mentioned for three different sacrifices. Each one teaches a different law relating either to the base of the altar or to the pouring of the remainder. The Gemara explains why these verses were available to be extrapolated and were not necessary for their straightforward meaning.

Study Guide The Gemara explores various hermeneutical methods used to derive halakhic laws - juxtaposition (hekesh), gezeira shava (verbal analogy), kal va'chomer (a fortiori reasoning), and binyan av (paradigm from precedent). It raises the question: can a law derived through one method serve as the basis for further derivation, either by the same method or a different one? They systematically examine each possible permutation, presenting logical arguments and textual proofs to evaluate the validity and limitations of such compound derivations. Importantly, this entire discussion is confined to laws pertaining to sacrificial items (kodashim) alone.

From where do we derive that the law regarding slaughtering of the burnt offering must be in the North, and that if not, it is disqualified? Since the sin offering is invalid if not slaughtered and its blood received in the North, and this requirement is derived from the burnt offering, a logical argument is made that the same requirement must apply to the burnt offering itself: how can a secondary prohibition be more strict than the primary prohibition? Three halakhot are brought to challenge this logic, but all difficulties are resolved. The Gemara then presents a second derivation for the requirement of the North for a burnt offering, based on the repetition of this requirement in Vayikra 4:29, following its initial mention in verse 24. The guilt offering must also be slaughtered and its blood collected in the North, and if not, it is disqualified. This is derived from two verses: Vayikra 7:2 and 14:13. A difficulty is raised regarding the use of the second verse, which relates to the sacrifices brought by the leper during the purification process, as that verse is needed for a different drasha. However, this challenge is resolved. The verse concerning the leper's sacrifices juxtaposes the guilt offering with both the burnt offering and the sin offering. If the law of the North for a guilt offering is derived from the burnt offering, why is the sin offering mentioned in that verse as well? Ravina explains that its inclusion teaches the principle that a law derived through juxtaposition cannot be used to teach that same law in another case through juxtaposition. Rava derives this principle from a different source: the bull sin offering of the kohen gadol, Vayikra 4:9–10. Can a law derived by juxtaposition be used to teach something through a gezeira shava? Initially, a proof is brought from the law regarding leprous clothing, which is derived from the law concerning a person with leprosy—originally derived through a gezeira shava. Rabbi Yochanan rejects this proof, arguing that the rules for deriving laws related to sacrificial items differ from those governing other laws. This distinction is demonstrated by the requirement of the North in the case of a guilt offering, which could have been derived from a gezeira shava from the sin offering, but was not - precisely for this reason.  

Why does the Mishna begin with the bull offering of Yom Kippur as its first example? Given that the primary halakha regarding slaughtering in the northern part of the Azara (Temple courtyard) is derived from the burnt offering, one might expect that to be the opening case. Why would the inner sin offerings appear before regular sin offerings? The verse that establishes the requirement of slaughtering in the North appears in the context of the sheep burnt offering. From this, the rabbis extrapolate the same requirement for burnt offerings brought from cattle. This derivation hinges on the presence of a connecting vav ("and") in the verse about sheep, which links it to the preceding section discussing cattle. The vav serves as a bridge, allowing the laws of the later section to inform those of the earlier one. However, the Gemara challenges this method of derivation, questioning how it can be valid for those who reject such connections and brings a braita to prove that there is a debate regarding this issue. The debate is about whether one brings a hanging guilt offering if one is in doubt that one committed mei'la, misuse of consecrated property. After initially suggesting that the disagreement was about whether one can derive laws of one section from another if they are connected by a vav, this explanation is rejected, and three alternative interpretations are proposed. Of these, only the final one is accepted. The sin offering, like the burnt offering, must be slaughtered in the North of the Azara. This is derived from Vayikra 4:29, which states that the sin offering is slaughtered "in the place of the burnt offering." Additional verses establish that not only must the blood be received in the North, but the priest receiving it must also be standing in the North. These requirements are shown to be essential and not merely ideal. In Vayikra 4:24, the verse says, "And he shall slaughter it in the North." The Gemara analyzes the word "it" to determine what it might exclude. Four possibilities are considered, and after rejecting three, the Gemara concludes that the correct interpretation is that the animal itself must be in the North, but the person performing the slaughter need not be. Since the sin offering is invalid if not slaughtered and its blood received in the North—and this requirement is derived from the burnt offering—a logical argument is made that the same strict requirement applies to the burnt offering itself.

A sin offering that is slaughtered for the sake of a non-sacred animal, the sacrifice is valid. However, if the owner slaughtered it thinking that the animal was not sacred, it is disqualified. The second category is called mitasek, one who did not at all intend to do the act. The source for this disqualification is brought from two verses, as two are necessary to prove that the intention for the act of slaughtering a sacrifice is an essential component. The Gemara explains that both tanna kama in the Mishna and Rabbi Yosi hold that the intention that is necessary, and can disqualify, is that of the kohen performing the sacrificial rites (or non-kohen who slaughtered). However, Rabbi Elazar b'Rabbi Yosi holds that the owner's intention can disqualify a sacrifice. Abaye brings two others who seem to have a similar opinion to Rabbi Elazar regarding other areas of halakha. Each case involves an instance where one person is performing an action on someone else's item, and the owner's intent can determine the status of the item. One case deals with slaughtering for idol worship, and the other is whether or not an item is considered significant enough to be liable for carrying on Shabbat. The fifth perek specifies details relating to all the sacrifices, including the location of the slaughtering and acceptance of the blood, where the blood is placed, etc. It begins with kodshei kodashim, a higher level of sanctity. The slaughtering of these sacrifices must take place on the northern side of the Azara. Before the Mishna details each of the offerings, it begins with a general statement about all kodshei kodashim and says their slaughtering is performed in the North. Why didn't it also mention another issue that is true for all of them - that their blood is collected in a sacred vessel? The Gemara explains that at first, they thought the blood of the leper could be collected in the kohen's hand, but they then realized that his hand can be used only for the blood going on the leper's ear, finger, and toe. The blood that is placed on the altar must first be placed in a sacred vessel. Since they originally thought otherwise, and two kohanim accept blood, each in a different manner, this is omitted from the opening line of the Mishna.

What is the source in the Mishna for the halakha that one is not liable for the laws of notar and impurity when eating blood? Rabbi Shimon and the rabbis disagree about whether one is liable for eating items that are not fit for consumption while in a state of impurity. Is their dispute limited to items that themselves became impure, or does it also apply to a person who is impure and eats sacrificial items that are pure? Sacrificial offerings are slaughtered with six intentions: for a specific sacrifice, for a specific person, for God, for consumption by fire, to produce a pleasing aroma, and to be accepted by God. In addition, sin and guilt offerings must be slaughtered with intent for the specific sin they atone for. Rabbi Yosi stated that even if the slaughterer did not explicitly have all these intentions in mind, the offering remains valid. This is due to a stipulation enacted by the court that the slaughterer should not articulate all these intentions, in order to prevent errors that could invalidate the sacrifice, as the intention is performed by the one slaughtering/offering the sacrifice, not the owner of the sacrifice.
