Leviticus 16:24-28

MLV(i) 24 And he will bathe his flesh in water in a holy place and put on his garments and come out and offer his burnt offering and the burnt offering of the people and make atonement for himself and for the people. 25 And he will burn upon the altar the fat of the sin offering. 26 And he who lets the goat go for the scapegoat will wash his clothes and bathe his flesh in water and afterward he will come into the camp.
27 And the bullock of the sin offering and the goat of the sin offering, whose blood was brought in to make atonement in the holy place, will be carried forth outside the camp and they will burn in the fire their skins and their flesh and their manure. 28 And he who burns them will wash his clothes and bathe his flesh in water and afterward he will come into the camp.
