Study Guide Zevachim 8

If any of the four sacrificial rites of a sin offering - slaughtering, collecting the blood, carrying it, or sprinkling it - are performed with the intent of a different sacrifice or for a different owner, the offering is disqualified. The Gemara investigates the source of this law. Initially, it cites verses that establish the requirement to slaughter, collect, and sprinkle the blood with the correct intent, both for the appropriate sacrifice and for the proper owner, and that failure to do so invalidates the offering. However, these sources do not explicitly prove that intent for a different sacrifice disqualifies the offering, nor that slaughtering and collecting must be done for the correct owner.

The Gemara first attempts to derive this from verses concerning the sin offerings of a nazirite and a leper, but both are rejected due to unique stringencies in each case. It then explores combinations - nazirite and leper, nazirite and standard sin offering, or leper and standard sin offering - but each pairing is also dismissed, as each has its own distinctive stringency.

Ultimately, Rava derives the requirement to perform all rites with the correct intent, from both the perspective of the sacrifice and the owner, from a verse that juxtaposes the peace offering with the sin offering, as the source for the basic law of proper intent is found in the laws of the peace offering, as explained in Zevachim 4. The verses previously cited in the sugya are then reinterpreted to teach that without proper designation, the offering is invalid—based on the principle that in kodashim (sacrificial laws), repetition in the Torah indicates necessity (l’akev).

The proof from the verses above pertains to a standard sin offering. The Gemara then asks: how do we know the same applies to a sin offering brought for idol worship or to a sliding-scale offering (korban oleh veyored)? These cases are derived through comparative analysis with other offerings mentioned previously.

The discussion shifts to the case of a Pesach offering. If one designates an animal for the Passover sacrifice but slaughters it on a day that is not Pesach, the offering is not disqualified and is instead brought as a peace offering. The father of Shmuel cites a verse from Vayikra 3:6, which discusses peace offerings, as the source. However, a difficulty arises: the verse may only support the case where the animal was offered as a peace offering. If it were offered with the intent for a different sacrifice, it might be disqualified.

To address this, the Gemara explains that the term zevach in the verse encompasses other types of offerings. Yet this resolution is unsatisfactory, as it could still be argued that if the Pesach was offered with intent for any other sacrifice, it should be brought as that sacrifice, not necessarily as a peace offering. To resolve this, the Gemara presents two alternative derivations from the verse and proceeds to analyze their validity.
