Leviticus 17:13-15

13"Any one also of the people of Israel, or of the strangers who sojourn among them, who takes in hunting any beast or bird that may be eaten shall pour out its blood and cover it with earth.

14For the life of every creature is its blood: its blood is its life. Therefore I have said to the people of Israel, You shall not eat the blood of any creature, for the life of every creature is its blood. Whoever eats it shall be cut off.

15And every person who eats what dies of itself or what is torn by beasts, whether he is a native or a sojourner, shall wash his clothes and bathe himself in water and be unclean until the evening; then he shall be clean.
