Leviticus 14:8-9

81The one to be cleansed shall then wash his clothes and shave off all his hair and bathe in water and 2be clean. Now afterward, he may enter the camp, but he 3shall stay outside his tent for seven days. 9It will be on the seventh day that he shall shave off all his hair: he shall shave his head and his beard and his eyebrows, even all his hair. He shall then wash his clothes and bathe his 4body in water and 5be clean.
