Leviticus 17:13-14

13“Any person from Bnei-Yisrael, or from the outsiders dwelling among them, who hunts as game any animal or bird that may be eaten, must drain its blood and cover it with dust.

14For the life of every creature, its blood is in its life. Therefore I said to Bnei-Yisrael: You are not to eat the blood of any kind of creature, for the life of every creature is its blood. Whoever eats it is to be cut off.
