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.
“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.
But if the priest examines it and there is no white hair in the spot and if it is not more than skin deep and has faded, then the priest is to isolate them for seven days.
If, however, the spot is unchanged and has not spread in the skin but has faded, it is a swelling from the burn, and the priest shall pronounce them clean; it is only a scar from the burn.
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.
