Leviticus 17:10-16 - Eating Blood And Carcasses Prohibited
10 And whatsoever man it be of the house of Israel or of the strangers that sojourn among you that eateth any manner of blood, I will set my face against that soul that eateth blood, and will destroy him from among his people, 11 for the life of the flesh is in the blood; and I have given it unto you upon the altar, to make an atonement for your souls, for blood shall make an atonement for the soul. 12 And therefore I said unto the children of Israel: See that no soul of you eat blood, nor yet any stranger that sojourneth among you.
13 "'Whatsoever man it be of the children of Israel or of the strangers that sojourn among you that hunteth and catcheth any beast or fowl that may be eaten, he shall pour out the blood and cover it with earth. 14 For the life of all flesh is in the blood, 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 in his blood, and whosoever therefore eateth it shall perish.
15 And whatsoever soul it be that eateth that which died alone or that which was torn with wild beasts: whether it be one of yourselves or a stranger, he shall wash his clothes and bathe himself in water, and shall be unclean unto the even, and then is he clean. 16 But and if he wash them not, nor wash his flesh, he shall bear his sin.'"
