Leviticus 17:10-16

10“Anyone from the house of Israel or from the aliens who reside among them who eats any blood, I will turn against that person who eats blood and cut him off from his people.

11For the life of a creature is in the blood, and I have appointed it to you to make atonement on the altar for your lives, since it is the lifeblood that makes atonement.

12Therefore I say to the Israelites: None of you and no alien who resides among you may eat blood.

13“Any Israelite or alien residing among them, who hunts down a wild animal or bird that may be eaten must drain its blood and cover it with dirt.

14Since the life of every creature is its blood, I have told the Israelites: You are not to eat the blood of any creature, because the life of every creature is its blood; whoever eats it must be cut off.

15“Every person, whether the native or the resident alien, who eats an animal that died a natural death or was mauled by wild beasts is to wash his clothes and bathe with water, and he will remain unclean until evening; then he will be clean.

16But if he does not wash his clothes and bathe himself, he will bear his iniquity.”
