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.
“When anyone has a swelling or a rash or a shiny spot on their skin that may be a defiling skin disease, they must be brought to Aaron the priest or to one of his sons who is a priest.
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.
On the seventh day the priest is to examine them again, and if the sore has faded and has not spread in the skin, the priest shall pronounce them clean; it is only a rash. They must wash their clothes, and they will be clean.
