The method of discriminating between a leprous spot and the scar of a burn. If there be any flesh, in the skin whereof there is a hot burning. This rendering indicates that the authors of the Authorized Version thought a disease of the nature of a carbuncle to be meant; but it is better to take the words literally as they are translated in the margin, If there be any flesh, in the skin whereof there is a burning of fire; that is, a scar from a burn, The leprous spot and the scar are to be distinguished as in the previous case.
An old nicer or burn is a more likely place for a leprous spot to appear than any part of the body which is sound, just as in the moral sphere sin fixes on some old wound of the soul to burst out in.
