Leviticus 16:20-34

“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. The bull for the sin offering and the goat for the sin offering, whose blood was brought in to make atonement in the Holy Place (Holy of Holies), shall be taken outside the camp; their skins, their meat, and their waste shall be burned in the fire. [Heb 13:11-13] Then he who burns them shall wash his clothes and bathe his body with water, and afterward he may come into the camp. “This shall be a permanent statute for you: in the seventh month (nearly October) on the tenth day of the month you shall humble yourselves [by fasting] and not do any work, whether the native-born or the stranger who lives temporarily among you; for it is on this day that atonement shall be made for you, to cleanse you; you will be clean from all your sins before the LORD. [Heb 10:1, 2; 1 John 1:7, 9] It is a Sabbath of solemn rest for you, and you shall humble yourselves; it is a permanent statute. So the priest who is anointed and ordained to serve and minister as priest in his father’s place shall make atonement: he shall wear the holy linen garments, and make atonement for the Holy Sanctuary, and he shall make atonement for the Tent of Meeting, and for the altar [of burnt offering in the court]. He shall also make atonement for the priests and for all the people of the assembly. This shall be a permanent statute for you, so that atonement may be made for the children of Israel for all their sins once a year.” So he did just as the LORD had commanded Moses.
