8The one being cleansed must wash his clothes, shave off all his hair, and bathe with water; then he will be ceremonially clean. Afterward, he may enter the camp, but he must remain outside his tent for seven days.
9On the seventh day he must shave off all his hair — his head, his beard, his eyebrows, and the rest of his hair. He must wash his clothes and bathe himself with water, and he will be clean.
— Leviticus 14:8-9
