Leviticus 17:10-16

10“If any one of the house of Israel or of the strangers who sojourn among them eats any blood, I will set my face against that person who eats blood and will cut him off from among his people. 11For the life of the flesh is in the blood, and I have given it for you on the altar to make atonement for your souls, for it is the blood that makes atonement by the life. 12Therefore I have said to the people of Israel, No person among you shall eat blood, neither shall any stranger who sojourns among you eat blood. 13“Any one also of the people of Israel, or of the strangers who sojourn among them, who takes in hunting any beast or bird that may be eaten shall pour out its blood and cover it with earth. 14For the life of every creature is its blood: its blood is its life. Therefore I have said to the people of Israel, You shall not eat the blood of any creature, for the life of every creature is its blood. Whoever eats it shall be cut off. 15And every person who eats what dies of itself or what is torn by beasts, whether he is a native or a sojourner, shall wash his clothes and bathe himself in water and be unclean until the evening; then he shall be clean. 16But if he does not wash them or bathe his flesh, he shall bear his iniquity.”
