Leviticus 13:19-21

New Century Version

¹⁹ If in the place where the boil was, there is a white swelling or a bright red spot, this place on the skin must be shown to the priest. ²⁰ And the priest must look at it. If the spot seems deeper than the skin and the hair on it has become white, the priest must announce that the person is unclean. The spot is a harmful skin disease that has broken out from inside the boil. ²¹ But if the priest looks at the spot and there are no white hairs in it and the spot is not deeper than the skin and it has faded, the priest must separate the person from other people for seven days.
