Leviticus 17:10-13

10If anyone from the house of Israel or a foreigner living among them eats any blood, I will set My face against that person and cut him off from among his people. 11For the life1 of the flesh is in the blood, and I have given it to you to make atonement for your souls upon the altar; for it is the blood that makes atonement for the soul. 12Therefore I say to the Israelites, ‘None of you may eat blood, nor may any foreigner living among you eat blood.’

13And if any Israelite or foreigner living among them hunts down a wild animal or bird that may be eaten, he must drain its blood and cover it with dirt.
