Leviticus 7:23-27

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 beasts may be put to any other use, but you must certainly not eat it. 25For whoever eats the fat of the animal from which 3an offering by fire is offered to the Lord, even the person who eats shall be cut off from his people. 264You are not to eat any blood, either of bird or animal, in any of your dwellings. 27Any person who eats any blood, even that person shall be cut off from his people.’”
