14:8 “The one being cleansed must then wash his clothes, shave off all his hair, and bathe in water, and so be clean. Then afterward he may enter the camp, but he must live outside his tent seven days. 14:9 When the seventh day comes he must shave all his hair – his head, his beard, his eyebrows, all his hair – and he must wash his clothes, bathe his body in water, and so be clean.
