Leviticus 17:10-11 NIV

[10] “ ‘I will set my face against any Israelite or any foreigner residing among them who eats blood, and I will cut them off from the people. [11] For the life of a creature is in the blood, and I have given it to you to make atonement for yourselves on the altar; it is the blood that makes atonement for one’s life.
