'Scapegoat' in the Bible

Aaron shall cast lots for the two goats, one lot for the Lord and the other lot for the scapegoat.

But the goat on which the lot for the scapegoat fell shall be presented alive before the Lord, to make atonement upon it, to send it into the wilderness as the scapegoat.

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.
