Mishnayos Zevachim Perek 6 Mishnah 7

In the case of a bird sin offering that the priest pinched not for its sake, or if he squeezed out its blood not for its sake, or if he did so for its sake and then not for its sake, or not for its sake and then for its sake, it is disqualified, like all other sin offerings that are disqualified when performed not for their sake (see 2a). A bird burnt offering sacrificed not for its sake is valid; it is just that it did not satisfy the obligation of the owner. With regard to both a bird sin offering and a bird burnt offering where the priest pinched its nape or squeezed out its blood with the intent to partake of an item whose typical manner is such that one partakes of it, or to burn an item whose typical manner is such that one burns it on the altar, outside its designated area, the offering is disqualified. But there is no liability to receive karet for one who partakes of the offering. If his intent was to eat it or burn it beyond its designated time, the offering is piggul and one is liable to receive karet for partaking of the offering, provided that the permitting factor, the blood, was sacrificed in accordance with its mitzva. How is the permitting factor sacrificed in accordance with its mitzva? If one pinched the nape in silence, i.e., with no disqualifying intent, and squeezed out its blood with the intent to partake of the parts typically eaten or to burn the portions that are to be burned on the altar, beyond its designated time; or in the case of one who pinched with the intent to partake of the offering or burn it on the altar beyond its designated time, and squeezed out its blood in silence; or in the case of one who pinched and squeezed out the blood with the intent to partake of the offering or burn it on the altar beyond its designated time, that is the case of a bird offering where the permitting factor is sacrificed in accordance with its mitzva. How is the permitting factor not sacrificed in accordance with its mitzva? If the priest pinched the nape of the bird with the intent to partake of it or burn it outside its designated area and squeezed out its blood with the intent to partake of it or burn it beyond its designated time, or he pinched with the intent to partake of it or burn it beyond its designated time and squeezed out its blood with the intent to partake of it or burn it outside its designated area, or if the priest pinched and squeezed out the blood with the intent to partake of it or burn it outside its designated area, or in the case of a bird sin offering where one pinched its nape not for its sake and squeezed out its blood with the intent of consuming it or burning it beyond its designated time, or in a case where he pinched its nape with the intent to consume it or burn it beyond its designated time and squeezed out its blood not for its sake, or in a case where he pinched its nape and squeezed out its blood not for its sake, that is a case of a bird offering whose permitting factor is not sacrificed in accordance with its mitzva. If one pinched the nape of the bird and squeezed out its blood with the intent to eat an olive-bulk of the offering outside its designated area and an olive-bulk the next day, or an olive-bulk the next day and an olive-bulk outside its designated area, or half an olive-bulk outside its designated area and half an olive-bulk the next day, or half an olive-bulk the next day and half an olive-bulk outside its designated area, the offering is disqualified and it does not include liability to receive karet. Rabbi Yehuda disagreed and said that this is the principle: If the improper intent with regard to the time preceded the intent with regard to the area, the offering is piggul and one is liable to receive karet for eating it. And if the intent with regard to the area preceded the intent with regard to the time, the offering is disqualified and it does not include liability to receive karet. And the Rabbis say: In both this case where the intent with regard to time came first and that case where the intent with regard to area came first, the offering is disqualified and it does not include liability to receive karet. If his intent was to eat half an olive-bulk and to burn half an olive-bulk not at the appropriate time or in the appropriate area, the offering is valid, because eating and burning do not join together.
