Leviticus 16:8

4 He is to wear the sacred linen tunic, with linen undergarments. He must tie a linen sash around him and put on the linen turban. These are holy garments, and he must bathe himself with water before he wears them.

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

6 Aaron is to present the bull for his sin offering and make atonement for himself and his household.

7 Then he shall take the two goats and present them before the LORD at the entrance to the Tent of Meeting.

8 After Aaron casts lots for the two goats, one for the LORD and the other for the scapegoat,

9 he shall present the goat chosen by lot for the LORD and sacrifice it as a sin offering.

10 But 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.

11 When 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.

12 Then he must take a censer full of burning coals from the altar before the LORD, and two handfuls of finely ground fragrant incense, and take them inside the veil.
