Leviticus 16:5-9

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

6“Aaron shall offer the bull as a sin offering, which is for himself, and make atonement for himself and for his house.

7He shall take the two goats and present them before the Lord at the door of the tabernacle of meeting.

8Then Aaron shall cast lots for the two goats: one lot for the Lord and the other lot for the scapegoat.

9And Aaron shall bring the goat on which the Lord’s lot fell, and offer it as a sin offering.
