Lev 17:10-14

Eating Blood Prohibited 10If anyone of the house of Israel or of the aliens who reside among them eats any blood, I will set my face against that person who eats blood, and will cut that person off from the people.11For the life of the flesh is in the blood; and I have given it to you for making atonement for your lives on the altar; for, as life, it is the blood that makes atonement.12Therefore I have said to the people of Israel: No person among you shall eat blood, nor shall any alien who resides among you eat blood.13And anyone of the people of Israel, or of the aliens who reside among them, who hunts down an animal or bird that may be eaten shall pour out its blood and cover it with earth.14For the life of every creature—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.
