Leviticus 17:15-16 - Regulations For Eating Carcasses
15 And every person who eats what dies of itself or what is torn by beasts, whether he is a native or a sojourner, shall wash his clothes and bathe himself in water and be unclean until the evening; then he shall be clean. 16 But if he does not wash them or bathe his flesh, he shall bear his iniquity."
