24 Or if there is a burn on the skin of the flesh, and if the diseased flesh in the burn becomes a bright place, red and white or white, 25 The priest is to see it: and if the hair on the bright place is turned white and it seems to go deeper than the skin, he is a leper: it has come out in the burn, and the priest will say that he is unclean: it is the leper's disease. 26 But if, after looking at it, the priest sees that there is no white hair on the bright place, and it is not deeper than the skin, and is not very bright, then let the priest keep him shut up for seven days: 27 And the priest is to see him again on the seventh day; if it is increased in the skin, then the priest will say that he is unclean: it is the leper's disease. 28 And if the bright place keeps the same size and gets no greater on the skin, but is less bright, it is the effect of the burn, and the priest will say that he is clean: it is the mark of the burn.
Matthew Henry's Commentary on Leviticus 13:24-28
Commentary on Leviticus 13:18-44
(Read Leviticus 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, verse 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.
