Leviticus 16:18-21 New American Standard Bible (NASB)

18. Then he shall go out to the altar that is before the Lord and make atonement for it, and shall take some of the blood of the bull and of the blood of the goat and put it on the horns of the altar on all sides.

19. With his finger he shall sprinkle some of the blood on it seven times and cleanse it, and from the impurities of the sons of Israel consecrate it.

20. "When he finishes atoning for the holy place and the tent of meeting and the altar, he shall offer the live goat.

21. Then Aaron shall lay both of his hands on the head of the live goat, and confess over it all the iniquities 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 and send it away into the wilderness by the hand of a man who stands in readiness.
