18 "If there is in the skin of one's body a boil and it heals, 19 and in the place of the boil there comes a white swelling or a reddish-white spot, then it shall be shown to the priest. 20 And the priest shall look, and if it appears deeper than the skin and its hair has turned white, then the priest shall pronounce him unclean. It is a case of leprous disease that has broken out in the boil. 21 But if the priest examines it and there is no white hair in it and it is not deeper than the skin, but has faded, then the priest shall shut him up seven days. 22 And if it spreads in the skin, then the priest shall pronounce him unclean; it is a disease. 23 But if the spot remains in one place and does not spread, it is the scar of the boil, and the priest shall pronounce him clean. 24 "Or, when the body has a burn on its skin and the raw flesh of the burn becomes a spot, reddish-white or white, 25 the priest shall examine it, and if the hair in the spot has turned white and it appears deeper than the skin, then it is a leprous disease. It has broken out in the burn, and the priest shall pronounce him unclean; it is a case of leprous disease. 26 But if the priest examines it and there is no white hair in the spot and it is no deeper than the skin, but has faded, the priest shall shut him up seven days, 27 and the priest shall examine him the seventh day. If it is spreading in the skin, then the priest shall pronounce him unclean; it is a case of leprous disease. 28 But if the spot remains in one place and does not spread in the skin, but has faded, it is a swelling from the burn, and the priest shall pronounce him clean, for it is the scar of the burn. 29 "When a man or woman has a disease on the head or the beard, 30 the priest shall examine the disease. And if it appears deeper than the skin, and the hair in it is yellow and thin, then the priest shall pronounce him unclean. It is an itch, a leprous disease of the head or the beard. 31 And if the priest examines the itching disease and it appears no deeper than the skin and there is no black hair in it, then the priest shall shut up the person with the itching disease for seven days, 32 and on the seventh day the priest shall examine the disease. If the itch has not spread, and there is in it no yellow hair, and the itch appears to be no deeper than the skin, 33 then he shall shave himself, but the itch he shall not shave; and the priest shall shut up the person with the itching disease for another seven days. 34 And on the seventh day the priest shall examine the itch, and if the itch has not spread in the skin and it appears to be no deeper than the skin, then the priest shall pronounce him clean. And he shall wash his clothes and be clean. 35 But if the itch spreads in the skin after his cleansing, 36 then the priest shall examine him, and if the itch has spread in the skin, the priest need not seek for the yellow hair; he is unclean. 37 But if in his eyes the itch is unchanged and black hair has grown in it, the itch is healed and he is clean, and the priest shall pronounce him clean.
38 "When a man or a woman has spots on the skin of the body, white spots, 39 the priest shall look, and if the spots on the skin of the body are of a dull white, it is leukoderma that has broken out in the skin; he is clean. 40 "If a man's hair falls out from his head, he is bald; he is clean. 41 And if a man's hair falls out from his forehead, he has baldness of the forehead; he is clean. 42 But if there is on the bald head or the bald forehead a reddish-white diseased area, it is a leprous disease breaking out on his bald head or his bald forehead. 43 Then the priest shall examine him, and if the diseased swelling is reddish-white on his bald head or on his bald forehead, like the appearance of leprous disease in the skin of the body, 44 he is a leprous man, he is unclean. The priest must pronounce him unclean; his disease is on his head.
Matthew Henry's Commentary on Leviticus 13:18-44
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.
