Leviticus 7:19-25

19The 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.

20The 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.

21When 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.’”

22Then the Lord spoke to Moses:

23“Tell the Israelites, ‘You must not eat any fat of an ox, sheep, or goat.

24Moreover, the fat of an animal that has died of natural causes and the fat of an animal torn by beasts may be used for any other purpose, but you must certainly never eat it.

25If anyone eats fat from the animal from which he presents a gift to the Lord, that person will be cut off from his people.
