The next ceremonial uncleanness is that of the leprosy, concerning which the law was very large and particular; we have the discovery of it in this chapter, and the cleansing of the leper in the next. Scarcely any one thing in all the levitical law takes up so much room as this. I. Rules are here given by which the priest must judge whether the man had the leprosy or no, according as the symptom was that appeared. 1. If it was a swelling, a scab, or a bright spot, ver 1-17. 2. If it was a bile, ver 18-23. 3. If it was in inflammation, ver 24-28. 4. If it was in the head or beard, ver 29-37. 5. If it was a bright spot, ver 38, 39. 6. If it was in a bald head, ver 40-44. II. Direction is given how the leper must be disposed of, ver 45, 46. III. Concerning the leprosy in garments, ver 47, etc.
Verses 1-17 The plague of leprosy was an uncleanness, rather than a disease. Christ is said to cleanse lepers, not to cure them. Common as the leprosy was among the Hebrews, during and after their residence in Egypt, we have no reason to believe that it was known among them before. Their distressed state and employment in that land must have rendered them liable to disease. But it was a plague often inflicted immediately by the hand of God. Miriam's leprosy, and Gehazi's, and king Uzziah's, were punishments of particular sins; no marvel there was care taken to distinguish it from a common distemper. The judgment of it was referred to the priests. And it was a figure of the moral pollutions of men's minds by sin, which is the leprosy of the soul, defiling to the conscience, and from which Christ alone can cleanse. The priest could only convict the leper, (by the law is the knowledge of sin,) but Christ can cure the sinner, he can take away sin. It is a work of great importance, but of great difficulty, to judge of our spiritual state. We all have cause to suspect ourselves, being conscious of sores and spots; but whether clean or unclean is the question. As there were certain marks by which to know it was leprosy, so there are marks of such as are in the gall of bitterness. The priest must take time in making his judgment. This teaches all, both ministers and people, not to be hasty in censures, nor to judge anything before the time. If some men's sins go before unto judgment, the sins of others follow after, and so do men's good works. If the person suspected were found to be clean, yet he must wash his clothes, because there had been ground for the suspicion. We have need to be washed in the blood of Christ from our spots, though not leprosy spots; for who can say, I am pure from sin?
That it may be suspected to be the leprosy.
Colour, &c. Hebrew, “a tumour, abscess, or white spot,” which are three marks of leprosy. (Calmet) — Leprosy. The leprosy was a figure of sin: and the observances prescribed in this and the following chapter, intimate what ought spiritually to be done, in order to be delivered from so great an evil, or preserved from it. (Challoner) — The authority of the priests in the new law to bind or loose sins, was hereby prefigured. (St. Chrysostom, de Sacerd. 3.) (Worthington)
1 And the Lord spake unto Moses and Aaron, saying, 2 When a man shall have in the skin of his flesh a rising, a scab, or bright spot, and it be in the skin of his flesh like the plague of leprosy; then he shall be brought unto Aaron the priest, or unto one of his sons the priests: 3 And the priest shall look on the plague in the skin of the flesh: and when the hair in the plague is turned white, and the plague in sight be deeper than the skin of his flesh, it is a plague of leprosy: and the priest shall look on him, and pronounce him unclean. 4 If the bright spot be white in the skin of his flesh, and in sight be not deeper than the skin, and the hair thereof be not turned white; then the priest shall shut up him that hath the plague seven days: 5 And the priest shall look on him the seventh day: and, behold, if the plague in his sight be at a stay, and the plague spread not in the skin; then the priest shall shut him up seven days more: 6 And the priest shall look on him again the seventh day: and, behold, if the plague be somewhat dark, and the plague spread not in the skin, the priest shall pronounce him clean: it is but a scab: and he shall wash his clothes, and be clean. 7 But if the scab spread much abroad in the skin, after that he hath been seen of the priest for his cleansing, he shall be seen of the priest again: 8 And if the priest see that, behold, the scab spreadeth in the skin, then the priest shall pronounce him unclean: it is a leprosy. 9 When the plague of leprosy is in a man, then he shall be brought unto the priest; 10 And the priest shall see him: and, behold, if the rising be white in the skin, and it have turned the hair white, and there be quick raw flesh in the rising; 11 It is an old leprosy in the skin of his flesh, and the priest shall pronounce him unclean, and shall not shut him up: for he is unclean. 12 And if a leprosy break out abroad in the skin, and the leprosy cover all the skin of him that hath the plague from his head even to his foot, wheresoever the priest looketh; 13 Then the priest shall consider: and, behold, if the leprosy have covered all his flesh, he shall pronounce him clean that hath the plague: it is all turned white: he is clean. 14 But when raw flesh appeareth in him, he shall be unclean. 15 And the priest shall see the raw flesh, and pronounce him to be unclean: for the raw flesh is unclean: it is a leprosy. 16 Or if the raw flesh turn again, and be changed unto white, he shall come unto the priest; 17 And the priest shall see him: and, behold, if the plague be turned into white; then the priest shall pronounce him clean that hath the plague: he is clean.
Flesh. These two signs indicated the species of leprosy called volatile, or impetigo, (Menochius) resembling a scab, which did not penetrate the flesh or bones, as our leprosy or elephantiasis does. (Vales.; Chap. xix.) — Separated from society. Hebrew, “he shall contaminate him.” See ver. 11. (Haydock) — Some assert, that the physician was first to be consulted. But none but the priests could declare them unclean, or set them at liberty. After they had pronounced sentence, the lepers might apply for medicines to others.
Hebrew, shall pollute him. That is, shrunken in, and be lower than the rest of the skin.
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, v. 4. But, if it was deeper than the skin, the man must be pronounced unclean, v. 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, 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, v. 4, 5. But if it spread much abroad, and continue to do so after several inspections, the case is bad, v. 7, 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, v. 10, 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 (v. 12, 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, 1 Tim 5 22, 24, 25. 6. If the person suspected was found to be clean, yet he must wash his clothes (v. 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.
