Leviticus 16:24–34

²⁴He is to bathe himself with water in a holy place and put on his own clothes. Then he must go out and sacrifice his burnt offering and the people’s burnt offering to make atonement for himself and for the people. ²⁵He is also to burn the fat of the sin offering on the altar.

²⁶The man who released the goat as the scapegoat must wash his clothes and bathe himself with water; afterward he may reenter the camp.

²⁷The bull for the sin offering and the goat for the sin offering, whose blood was brought into the Most Holy Place to make atonement, must be taken outside the camp; and their hides, flesh, and dung must be burned up. ²⁸The one who burns them must wash his clothes and bathe himself with water, and afterward he may reenter the camp.

²⁹This is to be a permanent statute for you: On the tenth day of the seventh month, you shall humble yourselves^e and not do any work — whether the native or the foreigner who resides among you — ³⁰because on this day atonement will be made for you to cleanse you, and you will be clean from all your sins before the LORD. ³¹It is a Sabbath of complete rest for you, that you may humble yourselves; it is a permanent statute.

³²The priest who is anointed and ordained to succeed his father as high priest shall make atonement. He will put on the sacred linen garments ³³and make atonement for the Most Holy Place,^f the Tent of Meeting, and the altar, and for the priests and all the people of the assembly. ³⁴This is to be a permanent statute for you, to make atonement once a year for the Israelites because of all their sins.”

And all this was done as the LORD had commanded Moses.
