Leviticus 17:13-15

13And whatsoever man there be of the children of Israel, or of the strangers that sojourn among them, who taketh in hunting any beast or bird that may be eaten; he shall pour out the blood thereof, and cover it with dust.

14For as to the life of all flesh, the blood thereof is all one with the life thereof: therefore I said unto the children of Israel, Ye shall eat the blood of no manner of flesh; for the life of all flesh is the blood thereof: whosoever eateth it shall be cut off. 15And every soul that eateth that which dieth of itself, or that which is torn of beasts, whether he be home-born or a sojourner, he shall wash his clothes, and bathe himself in water, and be unclean until the even: then shall he be clean.
