Leviticus 16:5-22

He shall take from the congregation of the Israelites [at their expense] two male goats as a sin offering and one ram as a burnt offering. Then Aaron shall present the bull as the sin offering for himself, and make atonement for himself and for his house. He shall take the two goats and present them before the LORD at the doorway of the Tent of Meeting. Aaron shall cast lots for the two goats—one lot for the LORD, the other lot for the scapegoat. Then Aaron shall bring the goat on which the LORD’S lot fell and offer it as a sin offering. But the goat on which the lot fell for the scapegoat shall be presented alive before the LORD to make atonement on it; it shall be sent into the wilderness as the scapegoat. “Aaron shall present the bull as the sin offering for himself and make atonement for himself and for his household (the other priests), and he shall kill the bull as the sin offering for himself. He shall take a censer full of burning coals from the [bronze] altar before the LORD, and two handfuls of finely ground sweet incense, and bring it inside the veil [into the Most Holy Place], and put the incense on the fire [in the censer] before the LORD, so that the cloud of the incense may cover the mercy seat that is on [the ark of] the Testimony, otherwise he will die. He shall take some of the bull’s blood and sprinkle it with his finger on the east side of the mercy seat; also in front of the mercy seat he shall sprinkle some of the blood with his finger seven times. “Then he shall kill the goat of the sin offering that is for [the sins of] the people and bring its blood within the veil [into the Most Holy Place] and do with its blood as he did with the blood of the bull, and sprinkle it on the mercy seat and in front of the mercy seat. [Heb 2:17] So he shall make atonement for the Holy Place (Holy of Holies) because of the uncleanness and transgressions of the Israelites, for all their sins. He shall also do this for the Tent of Meeting which is among them in the midst of their uncleanness (impurities). [Heb 9:22-24] There shall be no person in the Tent of Meeting when the high priest goes in to make atonement in the Holy Place [within the veil] until he comes out, so that he may make atonement for himself (his own sins) and for his household and for all the congregation of Israel. Then he shall go out to the altar [of burnt offering in the court] which is before the LORD and make atonement for it, and shall take some of the blood of the bull and 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 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]
