Leviticus 13:20-21

13:20 The priest will then examine it, and if it appears to be deeper than the skin and its hair has turned white, then the priest is to pronounce the person unclean. It is a diseased infection that has broken out in the boil. 13:21 If, however, the priest examines it, and there is no white hair in it, it is not deeper than the skin, and it has faded, then the priest is to quarantine him for seven days.

Leviticus 13:26

13:26 If, however, the priest examines it and there is no white hair in the bright spot, it is not deeper than the skin, and it has faded, then the priest is to quarantine him for seven days.

Leviticus 13:36-37

13:36 then the priest is to examine it, and if the scall has spread on the skin the priest is not to search further for reddish yellow hair. The person is unclean. 13:37 If, as far as the priest can see, the scall has stayed the same and black hair has sprouted in it, the scall has been healed; the person is clean. So the priest is to pronounce him clean.
