Leviticus 7:15-21

15The meat of his thanksgiving sacrifice of fellowship must be eaten on the day he offers it; he may not leave any of it until morning.

16“If the sacrifice he offers is a vow or a freewill offering, it is to be eaten on the day he presents his sacrifice, and what is left over may be eaten on the next day.

17But what remains of the sacrificial meat by the third day must be burned.

18If any of the meat of his fellowship sacrifice is eaten on the third day, it will not be accepted. It will not be credited to the one who presents it; it is repulsive. The person who eats any of it will bear his iniquity.

19“Meat that touches anything unclean must not be eaten; it is to be burned. Everyone who is clean may eat any other meat.

20But the one who eats meat from the Lord’s fellowship sacrifice while he is unclean, that person must be cut off from his people.

21If someone touches anything unclean, whether human uncleanness, an unclean animal, or any unclean, abhorrent creature, and eats meat from the Lord’s fellowship sacrifice, that person is to be cut off from his people.”
