Leviticus 16:20-34

“When Aaron has finished purifying the Most Holy Place and the Tabernacle and the altar, he must present the live goat. He will lay both of his hands on the goat’s head and confess over it all the wickedness, rebellion, and sins of the people of Israel. In this way, he will transfer the people’s sins to the head of the goat. Then a man specially chosen for the task will drive the goat into the wilderness. As the goat goes into the wilderness, it will carry all the people’s sins upon itself into a desolate land. “When Aaron goes back into the Tabernacle, he must take off the linen garments he was wearing when he entered the Most Holy Place, and he must leave the garments there. Then he must bathe himself with water in a sacred place, put on his regular garments, and go out to sacrifice a burnt offering for himself and a burnt offering for the people. Through this process, he will purify himself and the people, making them right with the LORD. He must then burn all the fat of the sin offering on the altar. “The man chosen to drive the scapegoat into the wilderness of Azazel must wash his clothes and bathe himself in water. Then he may return to the camp. “The bull and the goat presented as sin offerings, whose blood Aaron takes into the Most Holy Place for the purification ceremony, will be carried outside the camp. The animals’ hides, internal organs, and dung are all to be burned. The man who burns them must wash his clothes and bathe himself in water before returning to the camp. “On the tenth day of the appointed month in early autumn, you must deny yourselves. Neither native-born Israelites nor foreigners living among you may do any kind of work. This is a permanent law for you. On that day offerings of purification will be made for you, and you will be purified in the LORD’s presence from all your sins. It will be a Sabbath day of complete rest for you, and you must deny yourselves. This is a permanent law for you. In future generations, the purification ceremony will be performed by the priest who has been anointed and ordained to serve as high priest in place of his ancestor Aaron. He will put on the holy linen garments and purify the Most Holy Place, the Tabernacle, the altar, the priests, and the entire congregation. This is a permanent law for you, to purify the people of Israel from their sins, making them right with the LORD once each year.” Moses followed all these instructions exactly as the LORD had commanded him.
