Leviticus 7:18-21

7:18 If some of the meat of his peace offering sacrifice is ever eaten on the third day it will not be accepted; it will not be accounted to the one who presented it, since it is spoiled, and the person who eats from it will bear his punishment for iniquity. 7:19 The meat which touches anything ceremonially unclean must not be eaten; it must be burned up in the fire. As for ceremonially clean meat, everyone who is ceremonially clean may eat the meat. 7:20 The person who eats meat from the peace offering sacrifice which belongs to the Lord while his uncleanness persists will be cut off from his people. 7:21 When a person touches anything unclean (whether human uncleanness, or an unclean animal, or an unclean detestable creature) and eats some of the meat of the peace offering sacrifice which belongs to the Lord, that person will be cut off from his people.’”
