Zevachim 51 - November 4, 13 Cheshvan

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.
