Leviticus 16:17-24

When he goes in to make atonement in the holy place, no one shall be in the tent of meeting until he comes out, that he may make atonement for himself and for his household and for all the assembly of Israel. 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. 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. “When he finishes atoning for the holy place and the tent of meeting and the altar, he shall offer the live goat. 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. The goat shall bear on itself all their iniquities to a solitary land; and he shall release the goat in the wilderness. “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, and shall leave them there. He shall bathe his body with water in a holy place and put on his clothes, and come forth and offer his burnt offering and the burnt offering of the people and make atonement for himself and for the people.
