Leviticus 7:20-21

but the soul who eats of the flesh of the sacrifice of peace offerings, that belongs to the LORD, having his uncleanness on him, that soul shall be cut off from his people.

When anyone touches any unclean thing, the uncleanness of man, or an unclean animal, or any unclean abomination, and eats some of the flesh of the sacrifice of peace offerings, which belong to the LORD, that soul shall be cut off from his people.’”
