Talmud for Pesachim 124:14

Rebbi Simlai came to Rebbi Jonathan¹¹⁶Babli 62b. R. Simlai became famous as a preacher. K and the Medieval sources add that he was too young to be taught these matters.. He said to him, teach me homiletics. He answered him, I have a tradition from my forefathers not to teach homiletics either to a Babylonian or to a Southerner, since they are gross in spirit and have little learning. And you are from Nahardea and live in the South. He said to him, tell me this one thing, what is the difference between “for its purpose and not for its purpose” and “for those who eat it and those who cannot eat it”¹¹⁷Why is the former disqualified and the latter qualified.? He answered him, “for its purpose and not for its purpose”, the disqualification is intrinsic. “For those who eat it and those who cannot eat it”, the disqualification is of others. “For its purpose and not for its purpose”, you cannot pick out the disqualified from the qualified. [“For those who eat it and those who cannot eat it”, you can pick out the disqualified from the qualified.]^118aThe corrector’s addition is justified by K, which reads “you can’t” instead of “you can. “For its purpose and not for its purpose”, applies to all sacrifices¹¹⁸Mishnah Zevaḥim 1:1: “All sacrifices, except Pesaḥ and purification offerings, which were slaughtered not for their purpose are qualified but do not relieve their owners from their obligations.”; “for those who eat it and those who cannot eat it” applies only to the Pesaḥ.
