Leviticus 16:30

27And the bullock of the sin-offering and the goat of the sin-offering, whose blood has been brought in to make atonement in the holy place, [one] brings out to the outside of the camp, and they have burned their skins, and their flesh, and their dung with fire;

28and he who is burning them washes his garments, and has bathed his flesh with water, and afterward he comes into the camp.

29And it has been for a continuous statute to you, in the seventh month, on the tenth of the month, you humble yourselves, and do no work—the native and the sojourner who is sojourning in your midst;

30for on this day he makes atonement for you, to cleanse you; you are clean from all your sins before YHWH;

31it [is] a Sabbath of rest for you, and you have humbled yourselves—a continuous statute.

32And the priest whom he anoints, and whose hand he consecrates to act as priest instead of his father, has made atonement, and has put on the linen garments, the holy garments;

33and he has made atonement [for] the holy sanctuary; and [for] the Tent of Meeting, even [for] the altar he makes atonement; indeed, he makes atonement for the priests and for all the people of the assembly.
