Leviticus 16:20-22

20“When Aaron has finished making atonement for the Most Holy Place, the tent of meeting and the altar, he shall bring forward the live goat.

21He 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.

22The goat will carry on itself all their sins to a remote place; and the man shall release it in the wilderness.
