26 And he who lets the goat go to eAzazel shall wash his clothes and fbathe his body in water, and afterward he may come into the camp.

15 lAnd every person who eats what dies of itself or what is torn by beasts, mwhether he is a native or a sojourner, nshall wash his clothes and obathe himself in water and be unclean until the evening; then he shall be clean.
