Leviticus 16:10, 21, 22

But the goat chosen by lot as the scapegoat shall be presented alive before the LORD to be used for making atonement by sending it into the wilderness as a scapegoat.

He is to lay both hands on the head of the live goat and confess over it all the wickedness and rebellion of the Israelites—all their sins—and put them on the goat’s head. He shall send the goat away into the wilderness in the care of someone appointed for the task.

The goat will carry on itself all their sins to a remote place; and the man shall release it in the wilderness.
