Leviticus 17:10-14
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.
17:12 Therefore, I have said to the Israelites: No person among you is to eat blood, and no resident foreigner who lives among you is to eat blood.
17:13 “‘Any man from the Israelites or from the foreigners who reside in their midst who hunts a wild animal or a bird that may be eaten must pour out its blood and cover it with soil,
17:14 for the life of all flesh is its blood. So I have said to the Israelites: You must not eat the blood of any living thing because the life of every living thing is its blood – all who eat it will be cut off.
