Leviticus 13:18-23

18“If a boil on the skin has healed

19and in its place there is a white sore or a pink area, it must be shown to the priest.

20The priest will examine it. If it looks deeper than the rest of the skin and its hair has turned white, the priest must declare the person unclean. An infectious skin disease has developed in the boil.

21But if the priest examines the affected area and the hair in it is not white or 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.

22If the area has spread, the priest must declare him unclean. It is a skin disease.

23But if the irritated area has not spread, it is a scar caused by the boil. The priest must declare him clean.
