Leviticus 7:15-21

15‘1Now as for the flesh of the sacrifice of his thanksgiving peace offerings, it shall be eaten on the day of his offering; he shall not leave any of it over until morning. 16But if the sacrifice of his offering is a 2votive or a freewill offering, it shall be eaten on the day that he offers his sacrifice, and on the 3next day what is left of it may be eaten; 174but what is left over from the flesh of the sacrifice on the third day shall be burned with fire. 18So if any of the flesh of the sacrifice of his peace offerings should ever be eaten on the third day, he who offers it will not be accepted, and it will not be reckoned to his benefit. It shall be an 5offensive thing, and the person who eats of it will bear his own iniquity.

19‘Also the flesh that touches anything unclean shall not be eaten; it shall be burned with fire. 6As for other flesh, anyone who is clean may eat such flesh. 207But the person who eats the flesh of the sacrifice of peace offerings which belong to the Lord, 8in his uncleanness, that person 9shall be cut off from his people. 2110When anyone touches anything unclean, whether human uncleanness, or an unclean animal, or any unclean 11detestable thing, and eats of the flesh of the sacrifice of peace offerings which belong to the Lord, that person shall be cut off from his people.’”
