“If anyone has a sore, a rash, or an irritated area on his skin that turns into an infectious skin disease, he must be taken to the priest Aaron or to one of his sons who are also priests.
But if the priest examines it and the hair in it is not white and the affected area is not deeper than the rest of the skin but has faded, the priest must put him in isolation for seven days.
If the irritated area does not spread but has faded, it is only a sore caused by the burn. The priest must declare him clean, because it is a scar caused by the burn.
