Lv 16:29-34

The Fast. 29^l This shall be an everlasting statute for you: on the tenth day of the seventh month every one of you, whether a native or a resident alien, shall humble yourselves^* and shall do no work. 30For on this day atonement is made for you to make you clean; of all your sins you will be cleansed before the LORD. 31It shall be a sabbath of complete rest for you, on which you must humble yourselves—an everlasting statute.

32This atonement is to be made by the priest who has been anointed and ordained to the priesthood in succession to his father. He shall wear the linen garments, the sacred vestments, 33and purge the most sacred part of the sanctuary, as well as the tent of meeting, and the altar. He shall also make atonement for the priests and all the people of the assembly. 34This, then, shall be an everlasting statute for you: once a year atonement shall be made on behalf of the Israelites for all their sins. And Moses did as the LORD had commanded him.
