Leviticus 17:10-12

10And whatsoever man there be of the house of Israel, or of the strangers that sojourn among them, that eateth any manner of blood, I will set my face against that soul that eateth 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 to you upon the altar to make atonement for your souls: for it is the blood that maketh atonement by reason of the life. 12Therefore I said unto the children of Israel, No soul of you shall eat blood, neither shall any stranger that sojourneth among you eat blood.
