Leviticus 7:22-27

Israel's people must not eat blood or fat

22 The Lord said to Moses, 23 ‘Tell Israel's people this. They must not eat the fat from sheep, cows or goats. 24 A person can use the fat of a dead animal that he has found. But he must not eat it. 25 They must not eat the fat of an animal that they have burnt as a gift on the Lord's altar. They must send away from God's people anyone who does eat it. 26 You must not eat the blood of an animal or of a bird even if you are living in another country. 27 You must send away from Israel's people any person who eats blood.’
