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. 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.

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.
