Leviticus 7:23-27

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.

26And you must not eat any blood of the birds or the domesticated land animals in any of the places where you live.

27Any person who eats any blood – that person will be cut off from his people.’”
