Then the priest shall look upon it
And examine it, whether it has the marks and signs of a leprosy or not, such as follow: behold, [if] the hair in the bright spot be turned white;
which before was black, or of another colour from white, and is now, turned into the whiteness of chalk, as the Targum of Jonathan: and it [be in] sight deeper than the skin;
the same Targum is,
``and its sight or colour is deeper in being white like snow, more than the skin;''but this respects not the colour of it, as appearing to the sight, but the depth of the spot, going below the skin into the flesh, which, with the change of hair, are the two signs of leprosy, ( Leviticus 13:3 ) ; it [is] a leprosy broken out of the burning;
which sprung from thence, and what that had issued in: wherefore the priest shall pronounce him unclean;
a leper, and to be treated as such: it [is] the plague of leprosy;
being a plain case, according to the rules by which it was to be judged of.
