Leviticus 17:13-15

13And if any Israelite or foreigner living among them hunts down a wild animal or bird that may be eaten, he must drain its blood and cover it with dirt. 14For the life of all flesh is its blood. Therefore I have told the Israelites, ‘You must not eat the blood of any living thing, because the life of all flesh is its blood; whoever eats it must be cut off.’

15And any person, whether native or foreigner, who eats anything found dead or mauled by wild beasts must wash his clothes and bathe with water, and he will be unclean until evening; then he will be clean.
