Leviticus 17:13-15

13And every one of the children of Israel, and of the strangers who sojourn among them, that catcheth in the hunt a beast or fowl that may be eaten, he shall pour out the blood thereof, and cover it with earth;

14for as to the life of all flesh, its blood is the life in it; and I have said unto the children of Israel, Of the blood of no manner of flesh shall ye eat, for the life of all flesh is its blood: whoever eateth it shall be cut off.

15And every soul that eateth of a dead carcase, or of that which was torn, be it one home-born, or a stranger, he shall wash his clothes, and bathe in water, and be unclean until the even: then he shall be clean.
