26 But if on examination there is no white hair in the shiny spot and it doesn't look to be more than skin deep but has faded, the priest will put him in quarantine for seven days. 27 On the seventh day the priest will reexamine him. If by then it has spread over the skin, the priest will diagnose him as unclean; it is a serious skin disease and infectious. 28 If by that time the shiny spot has stayed the same and has not spread but has faded, it is only a swelling from the burn. The priest will pronounce him clean; it's only a scar from the burn. 29 "If a man or woman develops a sore on the head or chin, 30 the priest will offer a diagnosis. If it looks as if it is under the skin and the hair in it is yellow and thin, he will pronounce the person ritually unclean. It is an itch, an infectious skin disease. 31 But if when he examines the itch, he finds it is only skin deep and there is no black hair in it, he will put the person in quarantine for seven days. 32 On the seventh day he will reexamine the sore; if the itch has not spread, there is no yellow hair in it, and it looks as if the itch is only skin deep, 33 the person must shave, except for the itch; the priest will send him back to quarantine for another seven days. 34 If the itch has not spread, and looks to be only skin deep, the priest will pronounce him clean. The person can go home and wash his clothes; he is clean. 35 But if the itch spreads after being pronounced clean, 36 the priest must reexamine it; if the itch has spread in the skin, he doesn't have to look any farther, for yellow hair, for instance; he is unclean. 37 But if he sees that the itch is unchanged and black hair has begun to grow in it, the itch is healed. The person is clean and the priest will pronounce him clean.

38 "When a man or woman gets shiny or white shiny spots on the skin, 39 the priest is to make an examination; if the shiny spots are dull white, it is only a rash that has broken out: The person is clean. 40 "When a man loses his hair and goes bald, he is clean. 41 If he loses his hair from his forehead, he is bald and he is clean. 42 But if he has a reddish-white sore on scalp or forehead, it means a serious skin disease is breaking out. 43 The priest is to examine it; if the swollen sore on his scalp or forehead is reddish-white like the appearance of the sore of a serious skin disease, 44 he has a serious skin disease and is unclean. The priest has to pronounce him unclean because of the sore on his head. 45 "Any person with a serious skin disease must wear torn clothes, leave his hair loose and unbrushed, cover his upper lip, and cry out, 'Unclean! Unclean!' 46 As long as anyone has the sores, that one continues to be ritually unclean. That person must live alone; he or she must live outside the camp.

47 "If clothing - woolen or linen clothing, 48 woven or knitted cloth of linen or wool, leather or leatherwork - is infected with a patch of serious fungus 49 and if the spot in the clothing or the leather or the woven or the knitted material or anything made of leather is greenish or rusty, that is a sign of serious fungus. Show it to the priest. 50 The priest will examine the spot and then confiscate the material 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.
