Leviticus 16:26-28

ISV(i) 26 The one who sent away the male goat as a scapegoat is to wash his clothes and bathe his body with water. After doing so, he may enter the camp.
27 “The bull for the sin offering and the male goat for the sin offering, whose blood was brought into the sacred place, are to be taken outside the camp. Their skin, meat, and offal are to be incinerated. 28 The one who burns them is to wash his clothes and bathe his body with water. After doing so, he may enter the camp.”
