131 The Lord spoke to Moses and Aaron, saying, 2 "When a person has on the skin of his body a swelling or an eruption or a spot, and it turns into a case of leprous[1] disease on the skin of his body, then he shall be brought to Aaron the priest or to one of his sons the priests, 3 and the priest shall examine the diseased area on the skin of his body. And if the hair in the diseased area has turned white and the disease appears to be deeper than the skin of his body, it is a case of leprous disease. When the priest has examined him, he shall pronounce him unclean. 4 But if the spot is white in the skin of his body and appears no deeper than the skin, and the hair in it has not turned white, the priest shall shut up the diseased person for seven days. 5 And the priest shall examine him on the seventh day, and if in his eyes the disease is checked and the disease has not spread in the skin, then the priest shall shut him up for another seven days. 6 And the priest shall examine him again on the seventh day, and if the diseased area has faded and the disease has not spread in the skin, then the priest shall pronounce him clean; it is only an eruption. And he shall wash his clothes and be clean. 7 But if the eruption spreads in the skin, after he has shown himself to the priest for his cleansing, he shall appear again before the priest. 8 And the priest shall look, and if the eruption has spread in the skin, then the priest shall pronounce him unclean; it is a leprous disease. 9 "When a man is afflicted with a leprous disease, he shall be brought to the priest, 10 and the priest shall look. And if there is a white swelling in the skin that has turned the hair white, and there is raw flesh in the swelling, 11 it is a chronic leprous disease in the skin of his body, and the priest shall pronounce him unclean. He shall not shut him up, for he is unclean. 12 And if the leprous disease breaks out in the skin, so that the leprous disease covers all the skin of the diseased person from head to foot, so far as the priest can see, 13 then the priest shall look, and if the leprous disease has covered all his body, he shall pronounce him clean of the disease; it has all turned white, and 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 unclean. Raw flesh is unclean, for it is a leprous disease. 16 But if the raw flesh recovers and turns white again, then he shall come to the priest, 17 and the priest shall examine him, and if the disease has turned white, then the priest shall pronounce the diseased person clean; 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?
