131 And the Lord said to Moses and Aaron, 2 If a man has on his skin a growth or a mark or a white place, and it becomes the disease of a leper, let him be taken to Aaron the priest, or to one of the priests, his sons; 3 And if, when the priest sees the mark on his skin, the hair on the place is turned white and the mark seems to go deeper than the skin, it is the mark of a leper: and the priest, after looking at him, will say that he is unclean. 4 But if the mark on his skin is white, and does not seem to go deeper than the skin, and the hair on it is not turned white, then the priest will keep him shut up for seven days; 5 And the priest is to see him on the seventh day; and if, in his opinion, the place on his skin has not become worse and is not increased in size, then the priest will keep him shut up for seven days more: 6 And the priest is to see him again on the seventh day; and if the mark is less bright and is not increased on his skin, then let the priest say that he is clean: it is only a skin-mark, and after his clothing has been washed he will be clean. 7 But if the size of the mark on his skin is increased after he has been seen by the priest, let him go to the priest again: 8 And if, after looking at him, he sees that the mark is increased in his skin, let the priest say that he is unclean; he is a leper. 9 When the disease of a leper is seen on a man, let him be taken to the priest; 10 And if the priest sees that there is a white growth on the skin, and the hair is turned white, and there is diseased flesh in the growth, 11 It is an old disease in the skin of his flesh, and the priest will say that he is unclean; he will not have to be shut up, for he is clearly unclean. 12 And if the disease comes out all over his skin, from his head to his feet, as far as the priest is able to see, 13 And if the priest sees that all his flesh is covered with the leper's disease, the priest will say that he is clean: it is all turned white, he is clean. 14 But whenever diseased flesh is seen on him, he will be unclean. 15 And when the priest sees the diseased flesh he will say that he is unclean; the diseased flesh is unclean, he is a leper. 16 Or if the diseased flesh is turned again and changed to white then he is to come to the priest, 17 And the priest will see him: and if the place is turned white, then the priest will say that he is free from the disease.
18 And if a bad place has come out on the skin and is well again, 19 And on the same place there is a white growth of a bright mark, red and white, then let the priest see it; 20 And after looking at it, if it seems to go deeper than the skin, and the hair on it is turned white, then the priest will say that the man is unclean: it is the leper's disease, it has come out in the bad place. 21 But if, after looking at it, he sees that there are no white hairs on it, and it is not deeper than the skin, and it is not very bright, then let the priest keep him shut up for seven days: 22 And if it is increasing on the skin, the priest will say that he is unclean: it is a disease. 23 But if the bright mark keeps in the same place and gets no greater, it is the mark of the old wound, and the priest will say that he is clean. 24 Or if there is a burn on the skin of the flesh, and if the diseased flesh in the burn becomes a bright place, red and white or white, 25 The priest is to see it: and if the hair on the bright place is turned white and it seems to go deeper than the skin, he is a leper: it has come out in the burn, and the priest will say that he is unclean: it is the leper's disease. 26 But if, after looking at it, the priest sees that there is no white hair on the bright place, and it is not deeper than the skin, and is not very bright, then let the priest keep him shut up for seven days: 27 And the priest is to see him again on the seventh day; if it is increased in the skin, then the priest will say that he is unclean: it is the leper's disease. 28 And if the bright place keeps the same size and gets no greater on the skin, but is less bright, it is the effect of the burn, and the priest will say that he is clean: it is the mark of the burn. 29 And when a man or a woman has a disease on the head, or in the hair of the chin, 30 Then the priest is to see the diseased place: and if it seems to go deeper than the skin, and if there is thin yellow hair in it, then the priest will say that he is unclean: he has the mark of the leper's disease on his head or in the hair of his chin. 31 And after looking at the diseased place, if it does not seem to go deeper than the skin, and there is no black hair in it, then the priest will have him shut up for seven days: 32 And on the seventh day the priest will see the place: and if it is not increased, and there is no yellow hair in it, and it does not seem to go deeper than the skin, 33 Then his hair is to be cut off, but not on the diseased place, and he is to be shut up for seven days more: 34 And on the seventh day the priest will see the place: and if it is not increased, and does not seem to go deeper than the skin, the priest will say that he is clean: and after his clothing has been washed he will be clean. 35 But if the disease in his skin becomes worse after he has been made clean, 36 Then the priest is to see him: and if the mark is increased, the priest, without looking for the yellow hair, will say that he is unclean. 37 But if, in his opinion, the growth is stopped, and black hair has come up on it, the disease has gone; he is clean and the priest will say that he is clean.
38 And if a man or a woman has bright marks on the skin of their flesh, that is, bright white marks, 39 Then the priest is to see them: and if the white marks on their skin are not very bright, it is a skin disease which has come out on the skin; he is clean. 40 And if a man's hair has come out and he has no hair, still 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.
