Leviticus 17:10-15

¹⁰"If any man of the house of Israel or of the strangers that 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 upon the altar to make atonement for your souls; for it is the blood that makes atonement, by reason of 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. ¹³Any man also of the people of Israel, or of the strangers that sojourn among them, who takes in hunting any beast or bird that may be eaten shall pour out its blood and cover it with dust.

¹⁴"For the life of every creature is the blood of it; 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 that 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.
