5And he shall take from the congregation of Israel two male goats for a sin offering and one ram for a burnt offering.
6Aaron is to present the bull for his sin offering and make atonement for himself and his household.
7Then he shall take the two goats and present them before the LORD at the entrance to the Tent of Meeting.
8After Aaron casts lots for the two goats, one for the LORD and the other for the scapegoat,
9he shall present the goat chosen by lot for the LORD and sacrifice it as a sin offering.
— Leviticus 16:5-9
