Leviticus 13: Summary and Commentary

Verse 1

13:1–14:57 Concerning the regulations pertaining to infections, the principle of normal and abnormal comes into play (see “Clean, Unclean, and Holy” Theme Note). Whether in a person, clothing, or a building, infections are not normal: They indicate disease and death, the antitheses of wholeness, and were therefore declared unclean.

13:1-46 a serious skin disease (Hebrew tsara‘at): The Hebrew word is much broader than the severely disfiguring Hansen’s disease (see study note on 13:2). This larger range included symptoms such as an open sore (13:10), a boil (13:18), a burn (13:24), a sore on the head or chin (13:29), shiny white patches (13:38), or abnormal baldness (13:40). A general test was whether or not the abnormality was spreading (13:5-8). If so, a quarantine was ordered for as long as the disorder persisted (13:46). Not just people, but clothing (13:47-59) and even buildings (14:33-53) could contract such infections.

Verse 2

13:2 Skin disorders that were potentially contagious, such as swelling or a rash or discolored skin, required precautions to arrest their spread. Until a disorder was healed, the person was deemed unclean. The diseases described in this section may range from something as simple as an allergic rash, ringworm, or eczema to something as serious as gangrene. In Old Testament times, skin conditions were diagnosed by observation. The priests not only had a religious function, but they also served as physicians. • one of his sons: These priestly functions were to apply to future generations of priests as well.

Verse 3

13:3 more than skin-deep: This indicates that either the infection had eaten away the skin or the infection was visible beneath the skin. The white hair, together with the depression in the skin, indicated a skin disease that could spread (13:21-23). This made the person unclean (13:8).

Verse 4

13:4-5 The purpose of a quarantine was primarily diagnostic. It gave the priest an opportunity to examine the patient’s symptoms over a period of time.

Verse 8

13:8 If the rash had spread, then the priest declared the person unclean and the isolation became long-term.

Verse 10

13:10 The presence of an open sore was the crucial factor, because it indicated infection.

Verse 12

13:12-13 The completely white skin might refer simply to a loss of pigment (see also 13:3), whereas raw flesh (13:10, 14) indicated infection and ceremonial uncleanness.

Verse 24

13:24-25 The priest was to inspect the burned area to see if the wound had become infected (see 13:9-17). • hair . . . turned white: See 13:18-23.

Verse 30

13:30 The scabby sore suggested a fungal infection in the scalp or beard, hidden by hair. The symptoms included loss of hair and crusty skin.

Verse 38

13:38-39 If a skin rash showed pus or inflammation (13:42), it was probably an infection. If it only showed as a whitened area, it was probably vitiligo (leucoderma). With this harmless disorder, patches of skin lose their pigmentation.

Verse 42

13:42 A reddish white sore perhaps indicated pus and inflammation.

Verse 45

13:45 Tearing one’s clothing, letting one’s hair go uncombed, and covering the mouth were common ways of expressing mourning (10:6). • The cry of Unclean! Unclean! denoted social unacceptability as much as a health threat. It warned others that the individual’s skin disorder could be contagious and that holy things should not touch the unclean person.

Verse 46

13:46 The Tabernacle containing the Ark was in the center of the camp so that God could be considered as being in the camp (Deut 23:14). As long as an individual’s skin disorder persisted, he or she was to stay in isolation . . . outside the camp. This ensured that the infection would not spread to others and that the uncleanness would not come in contact with holy things. Even Miriam, sister of Moses and Aaron, had to spend seven days outside the camp (Num 12:15). This area was not exclusive to those suffering from skin disorders. The uneaten sin offering was taken there and burned (Lev 4:21). Criminals were executed there (24:14, 23), and corpses were carried there to avoid contaminating the area where the people lived (10:4-5). Even bodily functions were attended to outside the camp (Deut 23:12-14).

Verse 47

13:47-59 The rainy season in Israel, when the weather is humid and cool, extends from mid-October through March. Mildew flourishes during this time, and the spores can trigger serious allergic reactions, posing a health problem. The regulations for mildew in clothing were similar to those for infections in people. If the mildew showed signs of spreading, it was serious. If it could be stopped or washed or cut out, a garment could be saved. This process was also similar to the treatment of rot and mold in buildings (14:33-53).

13:47 mildew: The word refers here to a variety of molds or mildews that infected cloth or leather.

Verse 1

I. Concerning the plague of leprosy we may observe in general, 1. That it was rather an uncleanness than a disease; or, at least, so the law considered it, and therefore employed not the physicians but the priests about it. Christ is said to cleanse lepers, not to cure them. We do not read of any that died of the leprosy, but it rather buried them alive, by rendering them unfit for conversation with any but such as were infected like themselves. Yet there is a tradition that Pharaoh, who sought to kill Moses, was the first that ever was struck with this disease, and that he died of it. It is said to have begun first in Egypt, whence it spread into Syria. It was very well known to Moses, when he put his own hand into his bosom and took it out leprous. 2. That it was a plague inflicted immediately by the hand of God, and came not from natural causes, as other diseases; and therefore must be managed according to a divine law. Miriam's leprosy, and Gehazi's, and king Uzziah's, were all the punishments of particular sins: and, if generally it was so, no marvel there was so much care taken to distinguish it from a common distemper, that none might be looked upon as lying under this extraordinary token of divine displeasure but those that really were so. 3. That it is a plague not now known in the world; what is commonly called the leprosy is of a quite different nature. This seems to have been reserved as a particular scourge for the sinners of those times and places. The Jews retained the idolatrous customs they had learnt in Egypt, and therefore God justly caused this with some others of the diseases of Egypt to follow them. Yet we read of Naaman the Syrian, who was a leper, Kg2 5:1. 4. That there were other breakings-out in the body which did very much resemble the leprosy, but were not it, which might make a man sore and loathsome and yet not ceremonially unclean. Justly are our bodies called vile bodies, which have in them the seeds of so many diseases, by which the lives of so many are made bitter to them. 5. That the judgment of it was referred to the priests. Lepers were looked upon as stigmatized by the justice of God, and therefore it was left to his servants the priests, who might be presumed to know his mark best, to pronounce who were lepers and who were not. All the Jews say, "Any priest, though disabled by a blemish to attend the sanctuary, might be a judge of the leprosy, provided the blemish were not in his eye. And he might" (they say) "take a common person to assist him in the search, but the priest only must pronounce the judgment." 6. That it was a figure of the moral pollution of men's minds by sin, which is the leprosy of the soul, defiling to the conscience, and from which Christ alone can cleanse us; for herein the power of his grace infinitely transcends that of the legal priesthood, that the priest could only convict the leper (for by the law is the knowledge of sin), but Christ can cure the leper, he can take away sin. Lord, if thou wilt, thou canst make me clean, which was more than the priests could do, Mat 8:2. Some think that the leprosy signified, not so much sin in general as a state of sin, by which men are separated from God (their spot not being the spot of God's children), and scandalous sin, for which men are to be shut out from the communion of the faithful. It is a work of great importance, but of great difficulty, to judge of our spiritual state: we have all cause to suspect ourselves, being conscious to ourselves of sores and spots, but whether clean or unclean is the question. A man might have a scab (Lev 13:6) and yet be clean: the best have their infirmities; but, as there were certain marks by which to know that it was a leprosy, so there are characters of such as are in the gall of bitterness, and the work of ministers is to declare the judgment of leprosy and to assist those that suspect themselves in the trial of their spiritual state, remitting or retaining sin. And hence the keys of the kingdom of heaven are said to be given to them, because they are to separate between the precious and the vile, and to judge who are fit as clean to partake of the holy things and who as unclean must be debarred from them.

II. Several rules are here laid down by which the judgment of the priest must be governed. 1. If the sore was but skin-deep, it was to be hoped it was not the leprosy, Lev 13:4. But, if it was deeper than the skin, the man must be pronounced unclean, Lev 13:3. The infirmities that consist with grace do not sink deep into the soul, but the mind still serves the law of God, and the inward man delights in it, Rom 7:22, Rom 7:25. But if the matter be really worse than it shows, and the inwards be infected, the case is dangerous. 2. If the sore be at a stay, and do not spread, it is no leprosy, Lev 13:4, Lev 13:5. But if it spread much abroad, and continue to do so after several inspections, the case is bad, Lev 13:7, Lev 13:8. If men do not grow worse, but a stop be put to the course of their sins and their corruptions be checked, it is to be hoped they will grow better; but if sin get ground, and they become worse every day, they are going downhill. 3. If there was proud raw flesh in the rising, the priest needed not to wait any longer, it was certainly a leprosy, Lev 13:10, Lev 13:11. Nor is there any surer indication of the badness of a man's spiritual state than the heart's rising in self-conceit, confidence in the flesh, and resistance of the reproofs of the word and strivings of the Spirit. 4. If the eruption, whatever it was, covered all the skin from head to foot, it was no leprosy (Lev 13:12, Lev 13:13); for it was an evidence that the vitals were sound and strong, and nature hereby helped itself, throwing out what was burdensome and pernicious. There is hope in the small-pox when they come out well: so if men freely confess their sins, and hide them not, there is no danger comparable to theirs that cover their sins. Some gather this from it, that there is more hope of the profane than of hypocrites. The publicans and harlots went into the kingdom of heaven before scribes and Pharisees. In one respect, the sudden breakings-out of passion, though bad enough, are not so dangerous as malice concealed. Others gather this, that, if we judge ourselves, we shall not be judged; if we see and own that there is no health in us, no soundness in our flesh, by reason of sin, we shall find grace in the eyes of the Lord. 5. The priest must take time in making his judgment, and not give it rashly. If the matter looked suspicious, he must shut up the patient seven days, and then seven days more, that his judgment might be according to truth. This teaches all, both ministers and people, not to be hasty in their censures, nor to judge any thing before the time. If some men's sins go before unto judgment, the sins of others follow after, and so men's good works; therefore let nothing be done suddenly, Ti1 5:22, Ti1 5:24, Ti1 5:25. 6. If the person suspected was found to be clean, yet he must wash his clothes (Lev 13:6), because he had been under the suspicion, and there had been in him that which gave ground for the suspicion. Even the prisoner that is acquitted must go down on his knees. We have need to be washed in the blood of Christ from our spots, though they be not leprosy-spots; for who can say, I am pure from sin? though there are those who through grace are innocent from the great transgression.

Verse 18

The priest is here instructed what judgment to make if there was any appearance of a leprosy, either, 1. In an old ulcer, or bile, that has been healed, Lev 13:18, etc. When old sores, that seemed to be cured, break out again, it is to be feared there is a leprosy in them; such is the danger of those who, having escaped the pollutions of the world, are again entangled therein and overcome. Or, 2. In a burn by accident, for this seems to be meant, Lev 13:24, etc. The burning of strife and contention often proves the occasion of the rising up and breaking out of that corruption which witnesses to men's faces that they are unclean. 3. In a scall-head. And in this commonly the judgment turned upon a very small matter. If the hair in the scall was black, it was a sign of soundness; if yellow, it was an indication of a leprosy, Lev 13:30-37. The other rules in these cases are the same with those mentioned before. In reading of these several sorts of ailments, it will be good for us, 1. To lament the calamitous state of human life, which lies exposed to so many grievances. What troops of diseases are we beset with on every side! and they all entered by sin. 2. To give thanks to God if he has never afflicted us with any of these sores: if the constitution is healthful, and the body lively and easy, we are bound to glorify God with our bodies.

Verse 38

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.

Verse 47

This is the law concerning the plague of leprosy in a garment, whether linen or woollen. A leprosy in a garment, with discernible indications of it, the colour changed by it, the garment fretted, the nap worn off, and this in some one particular part of the garment, and increasing when it was shut up, and not to be got out by washing is a thing which to us now is altogether unaccountable. The learned confess that it was a sign and a miracle in Israel, an extraordinary punishment inflicted by the divine power, as a token of great displeasure against a person or family. 1. The process was much the same with that concerning a leprous person. The garment suspected to be tainted was not to be burnt immediately, though, it may be, there would have been no great loss of it; for in no case must sentence be given merely upon a surmise, but it must be shown to the priest. If, upon search, it was found that there was a leprous spot (the Jews say no bigger than a bean), it must be burnt, or at least that part of the garment in which the spot was, Lev 13:52, Lev 13:57. If the cause of the suspicion was gone, it must be washed, and then might be used, Lev 13:58. 2. The signification also was much the same, to intimate the great malignity there is in sin: it not only defiles the sinner's conscience, but it brings a stain upon all his employments and enjoyments, all he has and all he does. To those that are defiled and unbelieving is nothing pure, Tit 1:15. And we are taught hereby to hate even the garments spotted with the flesh, Jde 1:23. Those that make their clothes servants to their pride and lust may see them thereby tainted with a leprosy, and doomed to the fire, Isa 3:18-24. But the ornament of the hidden man of the heart is incorruptible, Pe1 3:4. The robes of righteousness never fret nor are moth-eaten.

Verse 3

the priest shall look on the plague in the skin of the flesh, &c.—The leprosy, as covering the person with a white, scaly scurf, has always been accounted an offensive blemish rather than a serious malady in the East, unless when it assumed its less common and malignant forms. When a Hebrew priest, after a careful inspection, discovered under the cutaneous blemish the distinctive signs of contagious leprosy, the person was immediately pronounced unclean, and is supposed to have been sent out of the camp to a lazaretto provided for that purpose. If the symptoms appeared to be doubtful, he ordered the person to be kept in domestic confinement for seven days, when he was subjected to a second examination; and if during the previous week the eruption had subsided or appeared to be harmless, he was instantly discharged. But if the eruption continued unabated and still doubtful, he was put under surveillance another week; at the end of which the character of the disorder never failed to manifest itself, and he was either doomed to perpetual exclusion from society or allowed to go at large. A person who had thus been detained on suspicion, when at length set at liberty, was obliged to "wash his clothes," as having been tainted by ceremonial pollution; and the purification through which he was required to go was, in the spirit of the Mosaic dispensation, symbolical of that inward purity it was instituted to promote.

Verse 7

But if the scab spread much abroad in the skin—Those doubtful cases, when they assumed a malignant character, appeared in one of two forms, apparently according to the particular constitution of the skin or of the habit generally. The one was "somewhat dark" [Lev 13:6] —that is, the obscure or dusky leprosy, in which the natural color of the hair (which in Egypt and Palestine is black) is not changed, as is repeatedly said in the sacred code, nor is there any depression in the dusky spot, while the patches, instead of keeping stationary to their first size, are perpetually enlarging their boundary. The patient laboring under this form was pronounced unclean by the Hebrew priest or physician, and hereby sentenced to a separation from his family and friends—a decisive proof of its being contagious.

Verse 9

if the rising be white—This BRIGHT WHITE leprosy is the most malignant and inveterate of all the varieties the disease exhibits, and it was marked by the following distinctive signs: A glossy white and spreading scale, upon an elevated base, the elevation depressed in the middle, but without a change of color; the black hair on the patches participating in the whiteness, and the scaly patches themselves perpetually enlarging their boundary. Several of these characteristics, taken separately, belong to other blemishes of the skin as well; so that none of them was to be taken alone, and it was only when the whole of them concurred that the Jewish priest, in his capacity of physician, was to pronounce the disease a malignant leprosy. If it spread over the entire frame without producing any ulceration, it lost its contagious power by degrees; or, in other words, it ran through its course and exhausted itself. In that case, there being no longer any fear of further evil, either to the individual himself or to the community, the patient was declared clean by the priest, while the dry scales were yet upon him, and restored to society. If, on the contrary, the patches ulcerated and quick or fungous flesh sprang up in them, the purulent matter of which, if brought into contact with the skin of other persons, would be taken into the constitution by means of absorbent vessels, the priest was at once to pronounce it an inveterate leprosy. A temporary confinement was them declared to be totally unnecessary, and he was regarded as unclean for life [DR. GOOD]. Other skin affections, which had a tendency to terminate in leprosy, though they were not decided symptoms when alone, were: "a boil" (Lev 13:18-23); "a hot burning,"—that is, a fiery inflammation or carbuncle (Lev 13:24-28); and "a dry scall" (Lev 13:29-37), when the leprosy was distinguished by being deeper than the skin and the hair became thin and yellow.

Verse 38

If a man . . . or a woman have in the skin of their flesh bright spots—This modification of the leprosy is distinguished by a dull white color, and it is entirely a cutaneous disorder, never injuring the constitution. It is described as not penetrating below the skin of the flesh and as not rendering necessary an exclusion from society. It is evident, then, that this common form of leprosy is not contagious; otherwise Moses would have prescribed as strict a quarantine in this as in the other cases. And hereby we see the great superiority of the Mosaic law (which so accurately distinguished the characteristics of the leprosy and preserved to society the services of those who were laboring under the uncontagious forms of the disease) over the customs and regulations of Eastern countries in the present day, where all lepers are indiscriminately proscribed and are avoided as unfit for free intercourse with their fellow men.

Verse 40

bald . . . forehead bald—The falling off of the hair, when the baldness commences in the back part of the head, is another symptom which creates a suspicion of leprosy. But it was not of itself a decisive sign unless taken in connection with other tokens, such as a "sore of a reddish white color" [Lev 13:43]. The Hebrews as well as other Orientals were accustomed to distinguish between the forehead baldness, which might be natural, and that baldness which might be the consequence of disease.

Verse 45

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.

Verse 46

he shall dwell alone; without the camp—in a lazaretto by himself, or associated with other lepers (Kg2 7:3, Kg2 7:8).

Verse 47

The garment . . . that the . . . leprosy is in—It is well known that infectious diseases, such as scarlet fever, measles, the plague, are latently imbibed and carried by the clothes. But the language of this passage clearly indicates a disease to which clothes themselves were subject, and which was followed by effects on them analogous to those which malignant leprosy produces on the human body—for similar regulations were made for the rigid inspection of suspected garments by a priest as for the examination of a leprous person. It has long been conjectured and recently ascertained by the use of a lens, that the leprous condition of swine is produced by myriads of minute insects engendered in their skin; and regarding all leprosy as of the same nature, it is thought that this affords a sufficient reason for the injunction in the Mosaic law to destroy the clothes in which the disease, after careful observation, seemed to manifest itself. Clothes are sometimes seen contaminated by this disease in the West Indies and the southern parts of America [WHITLAW, Code of Health]; and it may be presumed that, as the Hebrews were living in the desert where they had not the convenience of frequent changes and washing, the clothes they wore and the skin mats on which they lay, would be apt to breed infectious vermin, which, being settled in the stuff, would imperceptibly gnaw it and leave stains similar to those described by Moses. It is well known that the wool of sheep dying of disease, if it had not been shorn from the animal while living, and also skins, if not thoroughly prepared by scouring, are liable to the effects described in this passage. The stains are described as of a greenish or reddish color, according, perhaps, to the color or nature of the ingredients used in preparing them; for acids convert blue vegetable colors into red and alkalis change then into green [BROWN]. It appears, then, that the leprosy, though sometimes inflicted as a miraculous judgment (Num 12:10; Kg2 5:27) was a natural disease, which is known in Eastern countries still; while the rules prescribed by the Hebrew legislator for distinguishing the true character and varieties of the disease and which are far superior to the method of treatment now followed in those regions, show the divine wisdom by which he was guided. Doubtless the origin of the disease is owing to some latent causes in nature; and perhaps a more extended acquaintance with the archÃ&brvbrology of Egypt and the natural history of the adjacent countries, may confirm the opinion that leprosy results from noxious insects or a putrid fermentation. But whatever the origin or cause of the disease, the laws enacted by divine authority regarding it, while they pointed in the first instance to sanitary ends, were at the same time intended, by stimulating to carefulness against ceremonial defilement, to foster a spirit of religious fear and inward purity.
