Leviticus 14:8-9 - The Seven Days Of Purification
8 And he that is to be purified shall wash his clothes and shave off all his hair and wash himself with water, and he shall be clean; and after that he shall come into the camp and shall dwell outside of his tent seven days. 9 But it shall be that on the seventh day he shall shave all his hair off his head and his beard and his eyebrows; finally he shall shave off all his hair, and he shall wash his clothes; also he shall wash his flesh in water, and he shall be clean.
