24 Or, when the body has a burn on the skin and the raw flesh of the burn becomes a spot, reddish-white or white, 25 the priest shall examine it. If the hair in the spot has turned white and it appears deeper than the skin, it is a leprous disease; it has broken out in the burn, and the priest shall pronounce him unclean. This is a leprous disease. 26 But if the priest examines it and the hair in the spot is not white, and it is no deeper than the skin but has abated, the priest shall confine him seven days. 27 The priest shall examine him the seventh day; if it is spreading in the skin, the priest shall pronounce him unclean. This is a leprous disease. 28 But if the spot remains in one place and does not spread in the skin but has abated, it is a swelling from the burn, and the priest shall pronounce him clean; for it is the scar 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.
