Zevachim 63 - November 16, 25 Cheshvan
Description
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.
