Leviticus 16:24-28

241He shall bathe his 2body with water in a holy place and put on 3his clothes, and come forth and offer his burnt offering and the burnt offering of the people and make atonement for himself and for the people. 25Then he shall offer up in smoke the fat of the sin offering on the altar. 26The one who released the goat as the 4scapegoat 5shall wash his clothes and bathe his 6body with water; then afterward he shall come into the camp. 27But the bull of the sin offering and the goat of the sin offering, 7whose blood was brought in to make atonement in the holy place, shall be taken outside the camp, and they shall burn their hides, their flesh, and their refuse in the fire. 28Then the 8one who burns them shall wash his clothes and bathe his body with water, then afterward he shall come into the camp.
