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

⁷ And he shall take the two goats, and set them before Jehovah, before the entrance of the tent of meeting.

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