Leviticus 16:26-28

26The person who sent the goat away must wash his clothes and his body. He can return to the camp.

27Aaron had killed a bull and a goat. He took their blood into the Most Holy Place to make atonement. Someone must carry their dead bodies outside the camp. He must burn them. That man must burn the skin, the meat and the inside parts.

28The man who burnt the animals must wash his clothes and his body. Then he can return to the camp.
