Leviticus 7:20-21

201But the person who eats the flesh of the sacrifice of peace offerings which belong to the Lord, 2in his uncleanness, that person 3shall be cut off from his people. 214When anyone touches anything unclean, whether human uncleanness, or an unclean animal, or any unclean 5detestable 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.’”
