Leviticus 7:22-27

And the LORD spoke to Moses, saying, “Speak to the children of Israel, saying: ‘You shall not eat any fat, of ox or sheep or goat. And 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. For 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. Moreover you shall not eat any blood in any of your dwellings, whether of bird or beast. Whoever eats any blood, that person shall be cut off from his people.’ ”
