131 The Lord said to Moses and Aaron, 2 "When a man has on the skin of his body a swelling or an eruption or a spot, and it turns into a leprous disease on the skin of his body, then he shall be brought to Aaron the priest or to one of his sons the priests, 3 and the priest shall examine the diseased spot on the skin of his body; and if the hair in the diseased spot has turned white and the disease appears to be deeper than the skin of his body, it is a leprous disease; when the priest has examined him he shall pronounce him unclean. 4 But if the spot is white in the skin of his body, and appears no deeper than the skin, and the hair in it has not turned white, the priest shall shut up the diseased person for seven days; 5 and the priest shall examine him on the seventh day, and if in his eyes the disease is checked and the disease has not spread in the skin, then the priest shall shut him up seven days more; 6 and the priest shall examine him again on the seventh day, and if the diseased spot is dim and the disease has not spread in the skin, then the priest shall pronounce him clean; it is only an eruption; and he shall wash his clothes, and be clean. 7 But if the eruption spreads in the skin, after he has shown himself to the priest for his cleansing, he shall appear again before the priest; 8 and the priest shall make an examination, and if the eruption has spread in the skin, then the priest shall pronounce him unclean; it is leprosy. 9 "When a man is afflicted with leprosy, he shall be brought to the priest; 10 and the priest shall make an examination, and if there is a white swelling in the skin, which has turned the hair white, and there is quick raw flesh in the swelling, 11 it is a chronic leprosy in the skin of his body, and the priest shall pronounce him unclean; he shall not shut him up, for he is unclean. 12 And if the leprosy breaks out in the skin, so that the leprosy covers all the skin of the diseased person from head to foot, so far as the priest can see, 13 then the priest shall make an examination, and if the leprosy has covered all his body, he shall pronounce him clean of the disease; it has all turned white, and he is clean. 14 But when raw flesh appears on him, he shall be unclean. 15 And the priest shall examine the raw flesh, and pronounce him unclean; raw flesh is unclean, for it is leprosy. 16 But if the raw flesh turns again and is changed to white, then he shall come to the priest, 17 and the priest shall examine him, and if the disease has turned white, then the priest shall pronounce the diseased person clean; he is clean.
18 "And when there is in the skin of one's body a boil that has healed, 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 make an examination, and if it appears deeper than the skin and its hair has turned white, then the priest shall pronounce him unclean; it is the disease of leprosy, it has broken out in the boil. 21 But if the priest examines it, and the hair on it is not white and it is not deeper than the skin, but is dim, 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 diseased. 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 leprosy; it has broken out in the burn, and the priest shall pronounce him unclean; it 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 is dim, 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 leprous disease. 28 But if the spot remains in one place and does not spread in the skin, but is dim, 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 leprosy 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; and 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 seven days more; 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 checked, and black hair has grown in it, the itch is healed, 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 make an examination, and if the spots on the skin of the body are of a dull white, it is tetter that has broken out in the skin; he is clean. 40 "If a man's hair has fallen from his head, he is bald but he is clean.

(Read Leviticus 13:1-17)
The plague of leprosy was an uncleanness, rather than a disease. Christ is said to cleanse lepers, not to cure them. Common as the leprosy was among the Hebrews, during and after their residence in Egypt, we have no reason to believe that it was known among them before. Their distressed state and employment in that land must have rendered them liable to disease. But it was a plague often inflicted immediately by the hand of God. Miriam's leprosy, and Gehazi's, and king Uzziah's, were punishments of particular sins; no marvel there was care taken to distinguish it from a common distemper. The judgment of it was referred to the priests. And it was a figure of the moral pollutions of men's minds by sin, which is the leprosy of the soul, defiling to the conscience, and from which Christ alone can cleanse. The priest could only convict the leper, (by the law is the knowledge of sin,) but Christ can cure the sinner, he can take away sin. It is a work of great importance, but of great difficulty, to judge of our spiritual state. We all have cause to suspect ourselves, being conscious of sores and spots; but whether clean or unclean is the question. As there were certain marks by which to know it was leprosy, so there are marks of such as are in the gall of bitterness. The priest must take time in making his judgment. This teaches all, both ministers and people, not to be hasty in censures, nor to judge anything before the time. If some men's sins go before unto judgment, the sins of others follow after, and so do men's good works. If the person suspected were found to be clean, yet he must wash his clothes, because there had been ground for the suspicion. We have need to be washed in the blood of Christ from our spots, though not leprosy spots; for who can say, I am pure from sin?
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.
