Leviticus 7:22-25

22Then the Lord spoke to Moses, saying,

23“Speak to the sons of Israel, saying, ‘You shall not eat 1any fat from an ox, a sheep, or a goat.

24Also the fat of an animal which dies and the fat of an animal 2torn by animals may be put to any other use, but you certainly are not to eat it.

25For whoever eats the fat of the animal from which 3an offering by fire is offered to the Lord, the person who eats it shall also be cut off from his people.
