Leviticus 17:15-16 - Regulations For Eating Carcasses
15 And every soul that eats that which died of itself, or that which was torn by animals, whether it be one of your own country, or a stranger, he shall both wash his clothes, and bathe himself in water, and be unclean until the evening: then shall he be clean. 16 But if he washes them not, nor bathes his flesh; then he shall bear his iniquity.
