Leviticus 16:24 KJV

22And the goat shall bear upon him all their iniquities unto a land not inhabited: and he shall let go the goat in the wilderness.

23And Aaron shall come into the tabernacle of the congregation, and shall put off the linen garments, which he put on when he went into the holy place, and shall leave them there:

24And he shall wash his flesh with water in the holy place, and put on his garments, and come forth, and offer his burnt offering, and the burnt offering of the people, and make an atonement for himself, and for the people.

25And the fat of the sin offering shall he burn upon the altar.

26And he that let go the goat for the scapegoat shall wash his clothes, and bathe his flesh in water, and afterward come into the camp.
