Leviticus 17:11-14

11 Since the life of a living body is in its blood, I have made you put it on the altar, so that atonement may thereby be made for your own lives, because it is the blood, as the seat of life, that makes atonement. 12 That is why I have told the Israelites: No one among you, not even a resident alien, may partake of blood.

13 "Anyone hunting, whether of the Israelites or of the aliens residing among them, who catches an animal or a bird that may be eaten, shall pour out its blood and cover it with earth.

14 Since the life of every living body is its blood, I have told the Israelites: You shall not partake of the blood of any meat. Since the life of every living body is its blood, anyone who partakes of it shall be cut off.
