131 And the Lord spoke to Moses and Aaron, saying: 2 "When a man has on the skin of his body a swelling, a scab, or a bright spot, and it becomes on the skin of his body like a leprous sore, then he shall be brought to Aaron the priest or to one of his sons the priests. 3 The priest shall examine the sore on the skin of the body; and if the hair on the sore has turned white, and the sore appears to be deeper than the skin of his body, it is a leprous sore. Then the priest shall examine him, and pronounce him unclean. 4 But if the bright spot is white on the skin of his body, and does not appear to be deeper than the skin, and its hair has not turned white, then the priest shall isolate the one who has the sore seven days. 5 And the priest shall examine him on the seventh day; and indeed if the sore appears to be as it was, and the sore has not spread on the skin, then the priest shall isolate him another seven days. 6 Then the priest shall examine him again on the seventh day; and indeed if the sore has faded, and the sore has not spread on the skin, then the priest shall pronounce him clean; it is only a scab, and he shall wash his clothes and be clean. 7 But if the scab should at all spread over the skin, after he has been seen by the priest for his cleansing, he shall be seen by the priest again. 8 And if the priest sees that the scab has indeed spread on the skin, then the priest shall pronounce him unclean. It is leprosy. 9 "When the leprous sore is on a person, then he shall be brought to the priest. 10 And the priest shall examine him; and indeed if the swelling on the skin is white, and it has turned the hair white, and there is a spot of raw flesh in the swelling, 11 it is an old leprosy on the skin of his body. The priest shall pronounce him unclean, and shall not isolate him, for he is unclean. 12 "And if leprosy breaks out all over the skin, and the leprosy covers all the skin of the one who has the sore, from his head to his foot, wherever the priest looks, 13 then the priest shall consider; and indeed if the leprosy has covered all his body, he shall pronounce him clean who has the sore. It has all turned white. He is clean. 14 But when raw flesh appears on him, he shall be unclean. 15 And the priest shall examine the raw flesh and pronounce him to be unclean; for the raw flesh is unclean. It is leprosy. 16 Or if the raw flesh changes and turns white again, he shall come to the priest. 17 And the priest shall examine him; and indeed if the sore has turned white, then the priest shall pronounce him clean who has the sore. He is clean.

Commentary on Leviticus 13:1-17
(Read Leviticus 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?
