13:18-44 The priest is told what judgment to make, if there were any appearance of a leprosy in old sores; and such is the danger of those who having escaped the pollutions of the world are again entangled therein. Or, in a burn by accident, ver. 24. The burning of strife and contention often occasions the rising and breaking out of that corruption, which proves that men are unclean. Human life lies exposed to many grievances. With what troops of diseases are we beset on every side; and thy all entered by sin! If the constitution be healthy, and the body lively and easy, we are bound to glorify God with our bodies. Particular note was taken of the leprosy, if in the head. If the leprosy of sin has seized the head; if the judgment be corrupted, and wicked principles, which support wicked practices, are embraced, it is utter uncleanness, from which few are cleansed. Soundness in the faith keeps leprosy from the head.
But if the priest look on it,.... Upon a person in a like case as first described, having had a boil, and that healed, and afterwards a white swelling, or a bright spot in the place of it:
and, behold, there be no white hairs therein; not two hairs turned white, as Gersom interprets it:
and if it be not lower than the skin; the bright spot not lower than the skin; not having got into the flesh, only skin deep: the Targum of Jonathan is, not lower in whiteness than the skin; for the bright spot is described as white, and so the rising or swelling, Leviticus 13:19,
but be somewhat dark; or rather "contracted"; to which spreading is opposed in the next verse; See Gill on Leviticus 13:6,
then the priest shall shut him up seven days; to wait and see whether it will spread or not: a boil and burning, the Jews say, make a man unclean in one week, and by two signs, the white hair, and the spreading; by the white hair, both at the beginning and at the end of the week after dismission, and by spreading at the end of the week after it (q).
