Leviticus 17:9-11 New Revised Standard Version Catholic Edition (NRSVCE)
9 and does not bring it to the entrance of the tent of meeting, to sacrifice it to the Lord, shall be cut off from the people.
Eating Blood Prohibited
10 If 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. 11 For 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.
