Leviticus 13:25-27

New Century Version

²⁵ the priest must look at it. If the white spot seems deeper than the skin and the hair at that spot has become white, it is a harmful skin disease. The disease has broken out in the burn, and the priest must announce that the person is unclean. It is a harmful skin disease. 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.
