Leviticus 13:32-34

32On the seventh day the priest is to examine the sore, and if it has not spread and there is no yellow hair in it and it does not appear to be more than skin deep,

33then the man or woman must shave themselves, except for the affected area, and the priest is to keep them isolated another seven days.

34On the seventh day the priest is to examine the sore, and if it has not spread in the skin and appears to be no more than skin deep, the priest shall pronounce them clean. They must wash their clothes, and they will be clean.
