Leviticus 13:26-28

New Century Version

²⁶ But if the priest looks at the spot and there is no white hair in the bright spot, and the spot is no deeper than the skin and has faded, the priest must separate the person from other people for seven days. ²⁷ On the seventh day the priest must look at him again. If the spot has spread on the skin, the priest must announce that the person is unclean. It is a harmful skin disease. ²⁸ But if the bright spot has not spread on the skin but has faded, it is the swelling from the burn. The priest must announce that the person is clean, because the spot is only a scar from the burn.
