Leviticus 16:20

20 When Aaron has finished performing the ritual to purify the Most Holy Place, the rest of the Tent of the Lord's presence, and the altar, he shall present to the Lord the live goat chosen for Azazel.

Leviticus 16:20 In-Context

18 he must then go out to the altar for burnt offerings and purify it. He must take some of the bull's blood and some of the goat's blood and put it all over the projections at the corners of the altar.
19 With his finger he must sprinkle some of the blood on the altar seven times. In this way he is to purify it from the sins of the people of Israel and make it holy.
20 When Aaron has finished performing the ritual to purify the Most Holy Place, the rest of the Tent of the Lord's presence, and the altar, he shall present to the Lord the live goat chosen for Azazel.
21 He shall put both of his hands on the goat's head and confess over it all the evils, sins, and rebellions of the people of Israel, and so transfer them to the goat's head. Then the goat is to be driven off into the desert by someone appointed to do it.
22 The goat will carry all their sins away with him into some uninhabited land.
