Leviticus 17:8-12

8“Then you are to say to them: Anyone from the house of Israel, or from the outsiders dwelling among them, who offers a burnt offering or sacrifice,

9but does not bring it to the entrance of the Tent of Meeting to sacrifice it to Adonai, is to be cut off from his people.

10“Anyone from the house of Israel, or from the outsiders dwelling among them, who eats any kind of blood, I will set my face against that soul—the one who eats blood—and will cut him off from among his people.

11For the life of the creature is in the blood, and I have given it to you on the altar to make atonement for your lives—for it is the blood that makes atonement because of the life.

12Therefore I have said to Bnei-Yisrael: No person among you may eat blood, nor may any outsider dwelling among you eat blood.
