Leviticus 7:18-21

18You will not be accepted if any meat from the fellowship offering is eaten on the third day. You will not receive credit for it. It is repulsive to God. The person who eats any of it must be punished.

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.”
