Leviticus 16:10, 21-22

The other goat, the scapegoat chosen by lot to be sent away, will be kept alive, standing before the LORD. When it is sent away to Azazel in the wilderness, the people will be purified and made right with the LORD.

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