Leviticus 14:8-9 - The Seven Days Of Purification
8 The one to be cleansed shall wash his clothes, shave off all his hair, and bathe in water; and he shall be clean. After that he may come into the camp, but he shall stay outside of his tent for seven days. 9 On the seventh day he shall shave off all his hair: he shall shave his head and his beard and his eyebrows, even all his hair [on his body]. Then he shall wash his clothes and bathe his body in water, and be clean.
