Leviticus 14:8-9 - The Seven Days Of Purification
8 And he 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. And after that he may come into the camp, but live outside his tent seven days. 9 And on the seventh day he shall shave off all his hair from his head, his beard, and his eyebrows. He shall shave off all his hair, and then he shall wash his clothes and bathe his body in water, and he shall be clean.
