Leviticus 16:20-22

20“When Aaron has finished purifying the Most Holy Place and the Tabernacle and the altar, he must present the live goat.

21He will lay both of his hands on the goat’s head and confess over it all the wickedness, rebellion, and sins of the people of Israel. In this way, he will transfer the people’s sins to the head of the goat. Then a man specially chosen for the task will drive the goat into the wilderness.

22As the goat goes into the wilderness, it will carry all the people’s sins upon itself into a desolate land.
