18 And when the flesh hath in the skin thereof a boil, and it is healed, 19 and in the place of the boil there is a white rising, or a bright spot, reddish-white, then is shall be showed to the priest; 20 and the priest shall look; and, behold, if the appearance thereof be lower than the skin, and the hair thereof be turned white, then the priest shall pronounce him unclean: it is the plague of leprosy, it hath broken out in the boil. 21 But if the priest look on it, and, behold, there be no white hairs therein, and it be not lower than the skin, but be dim; then the priest shall shut him up seven days: 22 And if it spread abroad in the skin, then the priest shall pronounce him unclean: it is a plague. 23 But if the bright spot stay in its place, and be not spread, it is the scar of the boil; and the priest shall pronounce him clean. 24 Or when the flesh hath in the skin thereof a burning by fire, and the quick [flesh] of the burning become a bright spot, reddish-white, or white; 25 then the priest shall look upon it; and, behold, if the hair in the bright spot be turned white, and the appearance thereof be deeper than the skin; it is leprosy, it hath broken out in the burning: and the priest shall pronounce him unclean: it is the plague of leprosy. 26 But if the priest look on it, and, behold, there be no white hair in the bright spot, and it be no lower than the skin, but be dim; then the priest shall shut him up seven days: 27 and the priest shall look upon him the seventh day: if it spread abroad in the skin, then the priest shall pronounce him unclean: it is the plague of leprosy. 28 And if the bright spot stay in its place, and be not spread in the skin, but be dim; it is the rising of the burning, and the priest shall pronounce him clean: for it is the scar of the burning. 29 And when a man or woman hath a plague upon the head or upon the beard, 30 then the priest shall look on the plague; and, behold, if the appearance thereof be deeper than the skin, and there be in it yellow thin hair, then the priest shall pronounce him unclean: it is a scall, it is leprosy of the head or of the beard. 31 And if the priest look on the plague of the scall, and, behold, the appearance thereof be not deeper than the skin, and there be no black hair in it, then the priest shall shut up [him that hath] the plague of the scall seven days: 32 And in the seventh day the priest shall look on the plague; and, behold, if the scall be not spread, and there be in it no yellow hair, and the appearance of the scall be not deeper than the skin, 33 then he shall be shaven, but the scall shall he not shave; and the priest shall shut up [him that hath] the scall seven days more: 34 and in the seventh day the priest shall look on the scall; and, behold, if the scall be not spread in the skin, and the appearance thereof be not deeper than the skin; then the priest shall pronounce him clean: and he shall wash his clothes, and be clean. 35 But if the scall spread abroad in the skin after his cleansing, 36 then the priest shall look on him; and, behold, if the scall be spread in the skin, the priest shall not seek for the yellow hair; he is unclean. 37 But if in his eyes the scall be at a stay, and black hair be grown up therein; the scall is healed, he is clean: and the priest shall pronounce him clean.
38 And when a man or a woman hath in the skin of the flesh bright spots, even white bright spots; 39 then the priest shall look; and, behold, if the bright spots in the skin of their flesh be of a dull white, it is a tetter, it hath broken out in the skin; he is clean. 40 And if a man's hair be fallen off his head, he is bald; [yet] is he clean. 41 And if his hair be fallen off from the front part of his head, he is forehead bald; [yet] is he clean. 42 But if there be in the bald head, or the bald forehead, a reddish-white plague; it is leprosy breaking out in his bald head, or his bald forehead. 43 Then the priest shall look upon him; and, behold, if the rising of the plague be reddish-white in his bald head, or in his bald forehead, as the appearance of leprosy in the skin of the flesh; 44 he is a leprous man, he is unclean: the priest shall surely pronounce him unclean; his plague is in 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.
