On the seventh day the priest is to examine that person, and if it is spreading in the skin, the priest shall pronounce them unclean; it is a defiling skin disease.
the priest is to examine the sore, and if it appears to be more than skin deep and the hair in it is yellow and thin, the priest shall pronounce them unclean; it is a defiling skin disease on the head or chin.
On 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.
But if the rash does spread in their skin after they have shown themselves to the priest to be pronounced clean, they must appear before the priest again.
