Leviticus 16:7-9

King James Version

⁷ And he shall take the two goats, and present them before the Lord at the door of the tabernacle of the congregation.

⁸ And Aaron shall cast lots upon the two goats; one lot for the Lord, and the other lot for the scapegoat.

⁹ And Aaron shall bring the goat upon which the Lord's lot fell, and offer him for a sin offering.
