Leviticus 7:20-21

20But if anyone who is unclean eats meat from the peace offering that belongs to the LORD, that person must be cut off from his people. 21If one touches anything unclean, whether human uncleanness, an unclean animal, or any unclean, detestable thing, and then eats any of the meat of the peace offering that belongs to the LORD, that person must be cut off from his people.”
