Leviticus 13:18

18 The flesh also, in which, even in the skin thereof, was a boil, and is healed, 19 And in the place of the boil there be a white rising, or a bright spot, white, and somewhat reddish, and it be showed to the priest; 20 And if, when the priest seeth it, behold, it be in sight lower than the skin, and the hair thereof be turned white; the priest shall pronounce him unclean: it is a plague of leprosy broken out of the boil. 21 But if the priest look on it, and, behold, there be no white hairs therein, and if it be not lower than the skin, but be somewhat dark; then the priest shall shut him up seven days: 22 And if it spread much abroad in the skin, then the priest shall pronounce him unclean: it is a plague. 23 But if the bright spot stay in his place, and spread not, it is a burning boil; and the priest shall pronounce him clean. 24 Or if there be any flesh, in the skin whereof there is a hot burning, and the quick flesh that burneth have a white bright spot, somewhat reddish, or white; 25 Then the priest shall look upon it: and, behold, if the hair in the bright spot be turned white, and it be in sight deeper than the skin; it is a leprosy broken out of the burning: wherefore 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 other skin, but be somewhat dark; then the priest shall shut him up seven days: 27 And the priest shall look upon him the seventh day: and if it be spread much 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 his place, and spread not in the skin, but it be somewhat dark; it is a rising of the burning, and the priest shall pronounce him clean: for it is an inflammation of the burning. 29 If a man or woman have a plague upon the head or the beard; 30 Then the priest shall see the plague: and, behold, if it be in sight deeper than the skin; and there be in it a yellow thin hair; then the priest shall pronounce him unclean: it is a dry scall, even a leprosy upon the head or beard. 31 And if the priest look on the plague of the scall, and, behold, it be not in sight deeper than the skin, and that there is 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 spread not, and there be in it no yellow hair, and the scall be not in sight deeper than the skin; 33 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, nor be in sight 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 much 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 yellow hair; he is unclean. 37 But if the scall be in his sight at a stay, and that there is black hair grown up therein; the scall is healed, he is clean: and the priest shall pronounce him clean. The priest is here instructed what judgment to make if there was any appearance of a leprosy, either, 1. In an old ulcer, or bile, that has been healed, v. 18 , &c. When old sores, that seemed to be cured, break out again, it is to be feared there is a leprosy in them; such is the danger of those who, having escaped the pollutions of the world, are again entangled therein and overcome. Or, 2. In a burn by accident, for this seems to be meant, v. 24 , &c. The burning of strife and contention often proves the occasion of the rising up and breaking out of that corruption which witnesses to men's faces that they are unclean. 3. In a scall-head. And in this commonly the judgment turned upon a very small matter. If the hair in the scall was black, it was a sign of soundness; if yellow, it was an indication of a leprosy, v. 30-37 . The other rules in these cases are the same with those mentioned before. In reading of these several sorts of ailments, it will be good for us, 1. To lament the calamitous state of human life, which lies exposed to so many grievances. What troops of diseases are we beset with on every side! and they all entered by sin. 2. To give thanks to God if he has never afflicted us with any of these sores: if the constitution is healthful, and the body lively and easy, we are bound to glorify God with our bodies.
