Leviticus 14:8-9

8And 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. 9And it shall be on the seventh day, that he shall shave all his hair off his head and his beard and his eyebrows, even all his hair he shall shave off: and he shall wash his clothes, and he shall bathe his flesh in water, and he shall be clean.
