Leviticus 16:20-26

“When he has finished atoning for the Holy Place and the Tent of Meeting and the altar, he shall present the live goat. Then Aaron shall lay both of his hands on the head of the live goat, and confess over it all the wickedness of the sons of Israel and all their transgressions in regard to all their sins; and he shall lay them on the head of the goat [the scapegoat, the sin-bearer], and send it away into the wilderness by the hand of a man who is prepared [for the task]. The goat shall carry on itself all their (the Israelites) wickedness, carrying them to a solitary (infertile) land; and he shall release the goat in the wilderness. [Ps 103:12; Is 53:11, 12; John 1:29] “Then Aaron shall come into the Tent of Meeting and take off the linen garments which he put on when he went into the Holy Place (Holy of Holies), and shall leave them there. He shall bathe his body with water in a holy place and put on his clothes, and come out and offer his burnt offering and that of the people, and make atonement for himself and for the people. And he shall offer up in smoke the fat of the sin offering on the altar. The man who released the goat as the [sin-bearing] scapegoat shall wash his clothes and bathe his body in water, and afterward he may come into the camp.
