Likened to the Peace-Offering That Brings Peace to the World

"And all the fat of the bull of the sin-offering" -- to include the bull of the Day of Atonement for the two kidneys and the lobe of the liver. "The sin-offering" -- to include the goats of idolatry and all that is stated in the matter. "From it" -- from what is attached. "As it is taken up from the ox of the peace sacrifice" -- what is explained in the ox of the peace sacrifice that is not explained here? Rather: just as peace-offerings are for their own sake, so too this is for its own sake. Just as peace-offerings bring peace to the world, so too this brings peace to the world. If so, just as peace-offerings require separation of the fat-tail, should this too require separation of the fat-tail? The text says "from the ox of the peace sacrifice" -- I likened it to the peace-offering of an ox and not to the peace-offering of a lamb. Yehudah ben Shmuel says: just as peace-offerings bring peace to the world, so too this brings peace to the world. If so, just as communal peace-sacrifices override the Sabbath and impurity, should this too override the Sabbath and impurity? The text says "from the ox of the peace sacrifice" -- I likened it to the peace-offering of an ox and did not liken it to the peace-offering of a lamb. Rava said: a thing learned by analogy [hekkesh] does not return and teach by analogy. From here: "as it is taken up from the ox of the peace sacrifice" -- for what law? For the lobe of the liver and the two kidneys and the goats of idolatry. And the bull for the community's inadvertent ruling -- in its own case it is not written, but it comes by analogy, and it is learned from the bull of the anointed priest. Therefore "as it is taken up" was needed, to be as if it were written in its own case, so that a thing learned by analogy should not return and teach by analogy. Rav Pappa said to Rava: let it write it in its own case and not draw the analogy. Had it written it in its own case and not drawn the analogy, I would say a thing learned by analogy returns and teaches; and if you say, if so, let it draw the analogy -- it preferred to write it in its own case rather than derive it by analogy. Therefore it wrote and drew the analogy, so that a thing learned by analogy should not return and teach by analogy.
