Azazel

And Aaron shall cast lots upon the two goats; one lot for Jehovah, and the other lot for Azazel.

But the goat, on which the lot fell for Azazel, shall be set alive before Jehovah, to make atonement for him, to send him away for Azazel into the wilderness.

And he that letteth go the goat for Azazel shall wash his clothes, and bathe his flesh in water, and afterward he shall come into the camp.
