Leviticus 13:25-27

Revised Standard Version

²⁵ the priest shall examine it, and if the hair in the spot has turned white and it appears deeper than the skin, then it is leprosy; it has broken out in the burn, and the priest shall pronounce him unclean; it is a leprous disease. ²⁶ But if the priest examines it, and the hair in the spot is not white and it is no deeper than the skin, but is dim, the priest shall shut him up seven days, ²⁷ and the priest shall examine him the seventh day; if it is spreading in the skin, then the priest shall pronounce him unclean; it is a leprous disease.
