Zevachim 8:4-5

Zevachim 8:4

Rabbi Eliezer says that if the limbs of a sin offering got mixed up with the limbs of a burnt offering, then all of them must be burned on the altar, considering the flesh of the sin offering like wood (as opposed to being burned for its aroma). The Sages say that the sacrifices should be left past their permitted eating time and then taken to the place of burning.

Zevachim 8:5

Rabbi Eliezer says that if the limbs of sacrifices got mixed up with the limbs of blemished animals, then if the kohein already offered the head of one of them, he should offer all the heads; if he offered the leg of one of them, he should offer all the legs. The Sages say that even if all of the limbs were already offered except for one, that one is still taken to the place of burning.
