(4) If the bright spot be white.--But if upon inspection there merely appeared a white spot in the skin, and the above named two symptoms were absent, the case was not to be decided.

Then the priest shall shut up him that hath the plague.--The individual thus suspected was to be separated from the rest of the community for seven days, during which time it would be seen whether it actually developed itself into this disorder. According to the canons which obtained during the second Temple, if a bridegroom was seized with this distemper he could not be shut up during the nuptial week. It will be seen that the words "him that hath" are in italics, thus indicating that they are not in the text; but "plague" here, as we have seen in Leviticus 13:3, denotes plagued person.

Verses 4-8. - In case the symptoms are not decisive, then the priest shall shut up him that hath the plague seven days. The words thus translated would perhaps be better rendered, then the priest shall bind up the part affected for seven days. The priest is to delay his judgment for a week, and, if necessary, for a second week, during which period the patient is, according to the rendering, either to be confined to his house or, more probably, to have the spot bandaged. Whether the disease be or be not leprosy will probably have declared itself by the end of that time; and if the plague be somewhat dark on the fourteenth day, that is, if it has begun to lose its colour and to fade away, and has not spread in the skin, the priest is to decide that it is not real leprosy, and pronounce the man clean. He is still, however, to be kept under supervision, and if the spot is found to spread, he is to be pronounced unclean, as it is proved to be a leprosy.

13:1-17 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?If the bright spot be white in the skin of his flesh,.... The Targum of Jonathan is, white as chalk in the skin of his flesh; but other Jewish writers make the whiteness of the bright spot to be the greatest of all, like that of snow; See Gill on Leviticus 13:2,

and in sight be not deeper than the skin, and the hair thereof be not turned white; though it be a bright spot, and be very white, yet these two marks not appearing, it cannot be judged a leprosy, at most it is only suspicious: wherefore

then the priest, shall shut up him that hath the plague seven days; in whom the bright spot is, and of whom there is a suspicion of the plague of leprosy, but it is not certain; and therefore, in order to take time, and get further knowledge, the person was to be shut up from all company and conversation for the space of seven days; by which time it might be supposed, as Ben Gersom observes, that the case and state of the leprosy (if it was one) would be altered; and Aben Ezra remarks, that most diseases change or alter on the seventh day.
