Zevachim 90 - Shabbat December 13, 23 Kislev

Ravina bar Shila holds that the imurim, parts of kodashim kalim designated for burning, that are taken out of the Azara before the sprinkling of the blood are disqualified. The Gemara explores whether this aligns with a tannaitic dispute between Rabbi Eliezer and Rabbi Akiva, but Rav Papa clarifies that their disagreement pertains to a different case. The Gemara examines the order of precedence in the Mishna, which places bird offerings before meal offerings, and sin-related meal offerings before voluntary ones. Although one could argue for reversing the order, the Mishna's reasoning is deemed stronger and thus upheld. A sin offering, even of a bird, takes precedence over any burnt offering, even of an animal. This hierarchy is supported by three verses addressing different scenarios. Although three tannaitic sources appear to challenge this principle, the Gemara resolves these contradictions. Sin offerings also precede guilt offerings, except the guilt offering for a metzora (leper), because it comes to purify the leper. This offering, along with the guilt offering of a nazir, differs from other guilt offerings in two distinct ways. The order of precedence for sacrifices also applies to the consumption of their meat. Rabbi Shimon and Rabbi Meir disagree about whether spices of teruma may be added when cooking sacrificial meat. Rabbi Shimon permits it, while Rabbi Meir prohibits it due to the risk of disqualifying the teruma, which would then require burning.
