Leviticus 13:25-27

New American Standard Bible

²⁵ then the priest shall look at it. And if the hair in the bright spot has ^(A)turned white and it appears to be deeper than the skin, it is leprosy; it has broken out in the burn. Therefore, the priest shall pronounce him unclean; it is an infection of leprosy. ²⁶ But if the priest looks at it, and indeed, there is no white hair in the bright spot and it is no deeper than the skin, but is dim, then the priest shall ^[a]isolate him for seven days; ²⁷ and the priest shall look at him on the seventh day. If it spreads farther in the skin, then the priest shall pronounce him unclean; it is an infection of leprosy.
