Leviticus

¹¹For the life of the flesh is in the blood: and I have given it to you upon the altar to make atonement for your souls: for it is the blood that maketh atonement by reason of the life. ¹²Therefore I said unto the children of Israel, No soul of you shall eat blood, neither shall any stranger that sojourneth among you eat blood. ¹³And whatsoever man there be of the children of Israel, or of the strangers that sojourn among them, which taketh in hunting any beast or fowl 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 homeborn or a stranger, he shall wash his clothes, and bathe himself in water, and be unclean until the even: then shall he be clean. ¹⁶But if he wash them not, nor bathe his flesh, then he shall bear his iniquity.
