Leviticus 17:13-14

And 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.

For the life of all flesh is its blood. Therefore I have told the Israelites, ‘You must not eat the blood of any living thing, because the life of all flesh is its blood; whoever eats it must be cut off.’
