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. 41 And if the hair has gone from the front part of his head, so that he has no hair there, still he is clean. 42 But if, on his head or on his brow, where he has no hair, there is a red and white place, it is the disease of the leper coming out on his head or on his brow. 43 Then if the priest sees that the growth of the disease has become red and white on his head or on his brow where there is no hair, like the mark in the skin of a leper; 44 He is a leper and unclean; the priest is to say that he is most certainly unclean: the disease is in his head. 45 And the leper who has the disease on him is to go about with signs of grief, with his hair loose and his mouth covered, crying, Unclean, unclean. 46 While the disease is on him, he will be unclean. He is unclean: let him keep by himself, living outside the tent-circle.

47 And any clothing of wool or of linen in which is the mark of the disease; 48 If it is in the threads of the linen or of the wool, or in leather, or in anything made of skin; 49 If there are red or green marks on the clothing, or on the leather, or in the threads of the cloth, or in anything made of skin, it is the leper's disease: let the priest see it. 50 And after it has been seen by the priest, the thing which is so marked is to be shut up for seven days:

Matthew Henry's Commentary on Leviticus 13:26-50

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.

Commentary on Leviticus 13:45-46

(Read Leviticus 13:45-46)

When the priest had pronounced the leper unclean, it put a stop to his business in the world, cut him off from his friends and relations, and ruined all the comfort he could have in the world. He must humble himself under the mighty hand of God, not insisting upon his cleanness, when the priest had pronounced him unclean, but accepting the punishment. Thus must we take to ourselves the shame that belongs to us, and with broken hearts call ourselves "Unclean, unclean;" heart unclean, life unclean; unclean by original corruption, unclean by actual transgression; unclean, therefore deserving to be for ever shut out from communion with God, and all hope of happiness in him; unclean, therefore undone, if infinite mercy do not interpose. The leper must warn others to take heed of coming near him. He must then be shut out of the camp, and afterward, when they came to Canaan, be shut out of the city, town, or village where he lived, and dwell with none but those that were lepers like himself. This typified the purity which ought to be in the gospel church.

Commentary on Leviticus 13:47-59

(Read Leviticus 13:47-59)

The garment suspected to be tainted with leprosy was not to be burned immediately. If, upon search, it was found that there was a leprous spot, it must be burned, or at least that part of it. If it proved to be free, it must be washed, and then might be used. This also sets forth the great evil there is in sin. It not only defiles the sinner's conscience, but it brings a stain upon all he has and all that he does. And those who make their clothes servants to their pride and lust, may see them thereby tainted with leprosy. But the robes of righteousness never fret, nor are moth-eaten.
