SEV Biblia, Chapter 13:12
Mas si brotare la lepra cundiendo por la piel, y la lepra cubriere toda la piel del llagado desde su cabeza hasta sus pies, a toda vista de ojos del sacerdote;
John Gill's Bible Commentary
Ver. 12. And if a leprosy break out abroad in the skin , etc.] Or, if flowering it flowers f441 ; the man that has it on him looks like a plant or tree covered with white flowers, being spread all over him in white swellings, bright spots or scabs, as it follows: and the leprosy cover all the skin of [him that hath] the plague, from his head even to his foot ; such an one as the leper was that came to Christ for healing, said to be full of leprosy, ( Luke 5:12); and such in a mystical sense is every sinner, whether sensible of it or not, even from the Crown of the head to the sole of the foot, full of the wounds, bruises, and putrefying sores of sin, ( Isaiah 1:6); wheresoever the priest looketh ; that is, he cannot look any where upon any part of him but he sees the signs of the leprosy on him; and from whence the Jewish writers gather, that a priest that inspects leprous persons ought to have a clear sight, and to have both his eyes, and that the inspection should not be made in a dark house.
Matthew Henry Commentary
Verses 1-17 - The plague of leprosy was an uncleanness, rather than a disease. Chris is said to cleanse lepers, not to cure them. Common as the leprosy wa 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 the 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 referre to the priests. And it was a figure of the moral pollutions of men' minds by sin, which is the leprosy of the soul, defiling to the conscience, and from which Christ alone can cleanse. The priest coul 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 grea importance, but of great difficulty, to judge of our spiritual state We all have cause to suspect ourselves, being conscious of sores an spots; but whether clean or unclean is the question. As there wer 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 i making his judgment. This teaches all, both ministers and people, no 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?
