Leviticus 14:8-9 - The Seven Days Of Purification
8 And he that is to be cleansed shall wash his clothes, and shave off all his hair, and wash himself in water, that he may be clean: and after that he shall come into the camp, and shall tarry abroad out of his tent seven days. 9 But it shall be on the seventh day, that he shall shave all his hair off his head, and his beard, and his eye-brows, even all his hair he shall shave off; and he shall wash his clothes, also he shall wash his flesh in water, and he shall be clean.
