Leviticus 16:29-34

29On the tenth day of the seventh month, Israel's people must not eat any food. This is a rule that you must obey for all time. The people who are travelling with them must not eat any food. None of them must do any work.

30This day will make them clean from all their sins. The Lord will see them as clean people. This will be the Day of Atonement.

31It is a day when you do not eat any food. It is a day of rest. This is a rule from God and you must do this every year.

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.
