We have here,

I.Provisos that neither a freckled skin nor a bald head should be mistaken for a leprosy, Lev 13:38-41. Every deformity must not forthwith be made a ceremonial defilement. Elisha was jeered for his bald head (Kg2 2:23); but it was the children of Bethel, that knew not the judgments of their God, who turned it to his reproach.

II.A particular brand set upon the leprosy if at any time it did appear in a bald head: The plague is in his head, he is utterly unclean, Lev 13:44. If the leprosy of sin have seized the head, if the judgment be corrupted, and wicked principles which countenance and support wicked practices, be embraced, it is an utter uncleanness, from which few are ever cleansed. Soundness in the faith keeps the leprosy from the head, and saves conscience from being shipwrecked.

III.Directions what must be done with the convicted leper. When the priest, upon mature deliberation, had solemnly pronounced him unclean,

1.He must pronounce himself so, Lev 13:45. He must put himself into the posture of a mourner and cry, Unclean, unclean. The leprosy was not itself a sin, but it was a sad token of God's displeasure and a sore affliction to him that was under it. It was a reproach to his name, put a full stop to his business in the world, cut him off from conversation with his friends and relations, condemned him to banishment till he was cleansed, shut him out from the sanctuary, and was, in effect, the ruin of all the comfort he could have in this world. Heman, it would seem, either was a leper or alludes to the melancholy condition of a leper, Psa 88:8, etc. He must therefore, (1.) Humble himself under the mighty hand of God, not insisting upon his cleanness when the priest had pronounced him unclean, but justifying God and accepting the punishment of his iniquity. He must signify this by rending his clothes, uncovering his head, and covering his upper lip, all tokens of shame and confusion of face, and very significant of that self-loathing and self-abasement which should fill the hearts of penitents, the language of which is self-judging. Thus must we take to ourselves the shame that belongs to us, and with broken hearts call ourselves by our own name, Unclean, unclean - heart unclean, life unclean, unclean by original corruption, unclean by actual transgression - unclean, and therefore worthy to be for ever excluded from communion with God, and all hope of happiness in him. We are all as an unclean thing (Isa 64:6) - unclean, and therefore undone, if infinite mercy do not interpose. (2.) He must give warning to others to take heed of coming near him. Wherever he went, he must cry to those he saw at a distance, "I am unclean, unclean, take heed of touching me." Not that the leprosy was catching, but by the touch of a leper ceremonial uncleanness was contracted. Every one therefore was concerned to avoid it; and the leper himself must give notice of the danger. And this was all that the law could do, in that it was weak through the flesh; it taught the leper to cry, Unclean, unclean, but the gospel has put another cry into the lepers' mouths, Luk 17:12, Luk 17:13, where we find ten lepers crying with a loud voice, Jesus, Master, have mercy on us. The law only shows us our disease; the gospel shows us our help in Christ.

2.He must then be shut out of the camp, and afterwards, when they came to Canaan, out of the city, town, or village, where he lived, and dwell alone (Lev 13:46), associating with none but those that were lepers like himself. When king Uzziah became a leper, he was banished from his palace, and dwelt in a separate house, Ch2 26:21. And see Kg2 7:3. This typified the purity which ought to be preserved in the gospel church, by the solemn and authoritative exclusion of scandalous sinners, that hate to be reformed, from the communion of the faithful. Put away from among yourselves that wicked person, Co1 5:13.

His clothes shall be rent, etc. - The leprous person is required to be as one that mourned for the dead, or for some great and public calamity. He was to have his clothes rent in token of extreme sorrow; his head was to be made bare, the ordinary bonnet or turban being omitted; and he was to have a covering upon his upper lip, his jaws being tied up With a linen cloth, after the same manner in which the Jews bind up the dead, which custom is still observed among the Jews in Barbary on funeral occasions: a custom which, from Eze 24:17, we learn had prevailed very anciently among the Jews in Palestine. He was also to cry, Unclean, unclean, in order to prevent any person from coming near him, lest the contagion might be thus communicated and diffused through society; and hence the Targumist render it, Be not ye made unclean! Be not ye made unclean! A caution to others not to come near him.

The garments also, that the plague of leprosy is in,.... Whether this sort of leprosy proceeded from natural causes, or was extraordinary and miraculous, and came immediately from the hand of God, and was peculiar to the Jews, and unknown to other nations, is a matter of question; the latter is generally asserted by the Hebrew writers, as Maimonides (e), Abraham Seba (f), and others (g); but others are of opinion, and Abarbinel among the Jews, that it might be by the contact or touch of a leprous person. Indeed it must be owned, as a learned man (h) observes, that the shirts and clothes of a leper must be equally infectious, and more so than any other communication with him; and the purulent matter which adheres thereunto must needs infect; such who put on their clothes; for it may be observed, that it will get between the threads of garments, and stick like glue, and fill them up, and by the acrimony of it corrode the texture itself; so that experience shows that it is very difficult to wash such a garment without a rupture, and the stains are not easily got out: and it must be allowed that garments may be scented by diseases, and become infectious, and carry a disease from place to place, as the plague oftentimes is carried in wool, cotton, silk, or any bale goods; but whether all this amounts to the case before us is still a question. Some indeed have endeavoured to account for it by observing, that wool ill scoured, stuffs kept too long, and some particular tapestries, are subject to worms and moths which eat them, and from hence think it credible, that the leprosy in clothes, and in skins here mentioned, was caused by this sort of vermin; to which, stuffs and works, wrought in wool in hot countries, and in times when arts and manufactures were not carried to the height of perfection as now, might probably be more exposed (i); but this seems not to agree with this leprosy of Moses, which lay not in the garment being eaten, but in the colour and spread of it:

whether it be a woollen garment or a linen garment: and, according to the Misnic doctors (k), only wool and linen were defiled by leprosy; Aben Ezra indeed says, that the reason why no mention is made of silk and cotton is because the Scripture speaks of what was found (then in use), as in Exo 23:5; wherefore, according to him, woollen and linen are put for all other garments; though, he adds, or it may be the leprosy does not happen to anything but wool and linen; however, it is allowed, as Ben Gersom observes, that when the greatest part of the cloth is made of wool or linen, it was defiled by it: the Jewish canon is, if the greatest part is of camels hair, it is not defiled; but if the greatest part is of sheep, it is; and if half to half (or equal) it is defiled; and so flax, and hemp mixed together (l); the same rule is to be observed concerning them.

the leper in whom the plague is, his clothes shall be rent, &c.--The person who was declared affected with the leprosy forthwith exhibited all the tokens of suffering from a heavy calamity. Rending garments and uncovering the head were common signs of mourning. As to "the putting a covering upon the upper lip," that means either wearing a moustache, as the Hebrews used to shave the upper lip [CALMET], or simply keeping a hand over it. All these external marks of grief were intended to proclaim, in addition to his own exclamation "Unclean!" that the person was a leper, whose company every one must shun.
