24 "Or if the body receives a burn on its skin by fire, and the raw flesh of the burn becomes a bright spot, reddish-white or white, 25 then the priest shall examine it; and indeed if the hair of the bright spot has turned white, and it appears deeper than the skin, it is leprosy broken out in the burn. Therefore the priest shall pronounce him unclean. It is a leprous sore. 26 But if the priest examines it, and indeed there are no white hairs in the bright spot, and it is not deeper than the skin, but has faded, then the priest shall isolate him seven days. 27 And the priest shall examine him on the seventh day. If it has at all spread over the skin, then the priest shall pronounce him unclean. It is a leprous sore. 28 But if the bright spot stays in one place, and has not spread on the skin, but has faded, it is a swelling from the burn. The priest shall pronounce him clean, for it is the scar from 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.
