Leviticus 17:10-16

‘And whatever man of the house of Israel, or of the strangers who dwell among you, who eats any blood, I will set My face against that person who eats blood, and will cut him off from among his people. For the life of the flesh is in the blood, and I have given it to you upon the altar to make atonement for your souls; for it is the blood that makes atonement for the soul.’ Therefore I said to the children of Israel, ‘No one among you shall eat blood, nor shall any stranger who dwells among you eat blood.’ “Whatever man of the children of Israel, or of the strangers who dwell among you, who hunts and catches any animal or bird that may be eaten, he shall pour out its blood and cover it with dust; for it is the life of all flesh. Its blood sustains its life. Therefore I said to the children of Israel, ‘You shall not eat the blood of any flesh, for the life of all flesh is its blood. Whoever eats it shall be cut off.’ “And every person who eats what died naturally or what was torn by beasts, whether he is a native of your own country or a stranger, he shall both wash his clothes and bathe in water, and be unclean until evening. Then he shall be clean. But if he does not wash them or bathe his body, then he shall bear his guilt.”
