Leviticus 16:20-22

20“When he has finished atoning for the Holy Place, the Tent of Meeting and the altar, then he is to present the live goat.

21Aaron should lay both his hands on the head of the live goat and confess over it all the iniquities of Bnei-Yisrael and all their transgressions, all their sins. He should place them on the head of the goat and send it away into the wilderness by the hand of a man who is in readiness.

22The goat will carry all their iniquities by itself into a solitary land and he is to leave the goat in the wilderness.
