Lev 14:8-9

8The one who is to be cleansed shall wash his clothes, and shave off all his hair, and bathe himself in water, and he shall be clean. After that he shall come into the camp, but shall live outside his tent seven days.9On the seventh day he shall shave all his hair: of head, beard, eyebrows; he shall shave all his hair. Then he shall wash his clothes, and bathe his body in water, and he shall be clean.
