Leviticus 7:22-27

The LORD said to Moses, “Say to the Israelites: ‘Do not eat any of the fat of cattle, sheep or goats. The fat of an animal found dead or torn by wild animals may be used for any other purpose, but you must not eat it. Anyone who eats the fat of an animal from which a food offering may be presented to the LORD must be cut off from their people. And wherever you live, you must not eat the blood of any bird or animal. Anyone who eats blood must be cut off from their people.’ ”
