Leviticus 16:32-34

32The leader of the priests is a chosen son of Aaron. And he must make atonement. He will put on the special linen clothes that are holy. He will bring the people's offerings.

33He will make atonement for the Most Holy Place. He will make atonement for the Tent of Meeting. He will make atonement for the altar. He will make atonement for the priests and for all the people.

34He will make atonement for all the Israelites' sins once every year. This rule is for now and for all time.’ The people did everything in the way that the Lord had commanded Moses.
