Leviticus 16:19-22

With his finger he shall sprinkle some of the blood on the altar of burnt offering seven times and cleanse it and consecrate it from the uncleanness of the Israelites. “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]
