33the person is to shave himself but not shave the scaly area. Then the priest will quarantine the person who has the scaly outbreak for another seven days.

34The priest will examine the scaly outbreak on the seventh day, and if it has not spread on the skin and does not appear to be deeper than the skin, the priest is to pronounce the person clean. He is to wash his clothes, and he will be clean.
