Scapegoat

But the goat chosen by lot as the scapegoat shall be presented alive before the LORD to make atonement by sending it into the wilderness as the scapegoat.

After Aaron casts lots for the two goats, one for the LORD and the other for the scapegoat,

The man who released the goat as the scapegoat must wash his clothes and bathe himself with water; afterward he may reenter the camp.
