Leviticus 13:27

24 Or if there [is any] flesh, in the skin of which [there is] a hot burning, and the live [flesh] that burneth hath a white bright spot, somewhat reddish or white;

25 Then the priest shall look upon it: and behold, [if] the hair in the bright spot [is] turned white, and it [is in] sight deeper than the skin: it [is] a leprosy broken out of the burning: wherefore the priest shall pronounce him unclean: it [is] the plague of leprosy.

26 But if the priest shall look on it, and behold, [there is] no white hair in the bright spot, and it [is] no lower than the [other] skin, but [is] somewhat dark; then the priest shall shut him up seven days:

27 And the priest shall look upon him the seventh day: [and] if it [is] spread much in the skin, then the priest shall pronounce him unclean: it [is] the plague of leprosy,

28 And if the bright spot shall stay in its place, [and] not spread in the skin, but [be] somewhat dark; it [is] a rising of the burning, and the priest shall pronounce him clean: for it [is] an inflammation of the burning.

29 If a man or woman shall have a plague upon the head or the beard;

30 Then the priest shall see the plague: and behold, if it [is] in sight deeper than the skin, [and there is] in it a yellow thin hair; then the priest shall pronounce him unclean: it [is] a dry scall, [even] a leprosy upon the head or beard.
