Leviticus 7:19-21

19“Meat that touches anything unclean must not be eaten. It must be burned. Anyone who is clean may eat from these sacrifices.

20Those who eat meat from the Lord’s fellowship offering while unclean must be excluded from the people.

21Those who touch anything unclean, human or animal, or any other disgusting uncleanness and still eat the Lord’s fellowship offering must be excluded from the people.”
