Leviticus 7:22-25

22And the Lord spoke to Moses, saying,

23“Speak to the children of Israel, saying: ‘You shall not eat any fat, of ox or sheep or goat.

24And the fat of an animal that dies naturally, and the fat of what is torn by wild beasts, may be used in any other way; but you shall by no means eat it.

25For whoever eats the fat of the animal of which men offer an offering made by fire to the Lord, the person who eats it shall be cut off from his people.
