Leviticus 17:14-16

New Century Version

¹⁴ If blood is still in the meat, the animal’s life is still in it. So I give this command to the people of Israel: “Don’t eat meat that still has blood in it, because the animal’s life is in its blood. Anyone who eats blood must be cut off.”

¹⁵ “‘If a person, either a citizen or a foreigner, eats an animal that died by itself or was killed by another animal, he must wash his clothes and bathe in water. He will be unclean until evening; then he will be clean. ¹⁶ If he does not wash his clothes and bathe his body, he will be guilty of sin.’”
