Leviticus 13:27

24 `Or when flesh hath in its skin a fiery burning, and the quickening of the burning, the bright white spot, hath been very red or white,

25 and the priest hath seen it, and lo, the hair hath turned white in the bright spot, and its appearance is deeper than the skin; leprosy it is, in the burning it hath broken out, and the priest hath pronounced him unclean; it is a plague of leprosy.

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

27 and the priest hath seen him on the seventh day, if it spread greatly in the skin, then the priest hath pronounced him unclean; a plague of leprosy it is.

28 `And if the bright spot stay in its place, it hath not spread in the skin, and is become weak; a rising of the burning it is, and the priest hath pronounced him clean; for it is inflammation of the burning.

29 `And when a man (or a woman) hath in him a plague in the head or in the beard,

30 then hath the priest seen the plague, and lo, its appearance is deeper than the skin, and in it a thin shining hair, and the priest hath pronounced him unclean; it is a scall--it is a leprosy of the head or of the beard.
