Leviticus 13:21-23

Young's Literal Translation

²¹ `And if the priest see it, and lo, there is no white hair in it, and it is not lower than the skin, and is become weak, then hath the priest shut him up seven days;

²² and if it spread greatly in the skin, then hath the priest pronounced him unclean, it [is] a plague;

²³ and if in its place the bright spot stay -- it hath not spread -- it [is] an inflammation of the ulcer; and the priest hath pronounced him clean.
