Leviticus 17:13-15

13A person may catch an animal or a bird that is clean to eat. If he does, he must pour its blood on the ground. He must cover the blood with some earth.

14The animal's life is in its blood. That is why no Israelite should eat any animal's blood. You must send any person that eats blood away from your people.

15An Israelite or a foreign person may find a dead animal. If he eats it, he must wash his clothes and his body. He will be unclean until evening. Then he will become clean. A person might find an animal or a bird that a wild animal has killed. He must wash his clothes and his body. He will be unclean until evening.
