Leviticus 16:23-27

“Then Aaron shall come into the tent of meeting and take off the linen garments which he put on when he went into the Holy Place, and shall leave them there.

And he shall bathe his body with water in a holy place and put on his clothes, and come out and offer his burnt offering and the burnt offering of the people, and make atonement for himself and for the people.

Then he shall offer up in smoke the fat of the sin offering on the altar.

The one who released the goat as the scapegoat shall wash his clothes and bathe his body with water; then afterward he shall come into the camp.

But the bull of the sin offering and the goat of the sin offering, whose blood was brought in to make atonement in the Holy Place, shall be taken outside the camp, and they shall burn their hides, their flesh, and their refuse in the fire.
