Leviticus 7:18-21

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 1offensive 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. 2As for other flesh, anyone who is clean may eat such flesh. 203But the person who eats the flesh of the sacrifice of peace offerings which belong to the Lord, 4in his uncleanness, that person 5shall be cut off from his people. 216When anyone touches anything unclean, whether human uncleanness, or an unclean animal, or any unclean 7detestable 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.’”
