Leviticus 14:8-9 - The Seven Days Of Purification
8 "And he that is cleansed shall wash his clothes and shave off all his hair, and wash himself in water, and then he is clean. And after that he shall come into the host, but shall tarry without his tent seven days. 9 When the seventh day is come, he shall shave off all his hair both upon his head and his beard and on his brows: and even all the hair that is on him, shall be shaven off. And he shall wash his clothes and his flesh in water, and then he shall be clean.
