Leviticus 17:10-11

Prohibition against Eating Blood

17:10 “‘Any man from the house of Israel or from the foreigners who reside in their midst who eats any blood, I will set my face against that person who eats the blood, and I will cut him off from the midst of his people, 17:11 for the life of every living thing is in the blood. So I myself have assigned it to you on the altar to make atonement for your lives, for the blood makes atonement by means of the life.
