Leviticus 17:11-14

11For the life of a creature is in the blood, and I have given it to you to make atonement for yourselves on the altar; it is the blood that makes atonement for one’s life. Or atonement by the life in the blood

12Therefore I say to the Israelites, “None of you may eat blood, nor may any foreigner residing among you eat blood.” 13“ ‘Any Israelite or any foreigner residing among you who hunts any animal or bird that may be eaten must drain out the blood and cover it with earth,

14because the life of every creature is its blood. That is why I have said to the Israelites, “You must not eat the blood of any creature, because the life of every creature is its blood; anyone who eats it must be cut off.”
