Levítico 14:8

8 "The person to be cleansed must wash their clothes, shave off all their hair and bathe with water; then they will be ceremonially clean. After this they may come into the camp, but they must stay outside their tent for seven days.

8 And he that is to be cleansed shall wash his clothes, and shave off all his hair, and bathe himself in water; and he shall be clean: and after that he shall come into the camp, but shall dwell outside his tent seven days.
