LEVITICUS 16:5-10

⁵And he shall take of the congregation of the children of Israel two he-goats for a sin offering, and one ram for a burnt offering.

⁶And Aaron shall present the bullock of the sin offering, which is for himself, and make atonement for himself, and for his house.

⁷And he shall take the two goats, and set them before the LORD at the door of the tent of meeting.

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

⁹And Aaron shall present the goat upon which the lot fell for the LORD, and offer him for a sin offering.

¹⁰But the goat, on which the lot fell for Azazel, shall be set alive before the LORD, to make atonement for him, to send him away for Azazel into the wilderness.
