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.
10But the goat chosen by lot as the scapegoat shall be presented alive before the LORD to make atonement by sending it into the wilderness as the scapegoat.
11When Aaron presents the bull for his sin offering and makes atonement for himself and his household, he is to slaughter the bull for his own sin offering.
— Leviticus 16:6-11
