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 leprous disease on the skin of his body, he shall be brought to Aaron the priest or to one of his sons the priests. 3 The priest shall examine the disease 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 leprous disease; after the priest has examined him he shall pronounce him ceremonially 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 confine the diseased person for seven days. 5 The priest shall examine him on the seventh day, and if he sees that the disease is checked and the disease has not spread in the skin, then the priest shall confine him seven days more. 6 The priest shall examine him again on the seventh day, and if the disease has abated and the disease has not spread in the skin, 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 The priest shall make an examination, and if the eruption has spread in the skin, the priest shall pronounce him unclean; it is a leprous disease. 9 When a person contracts a leprous disease, he shall be brought to the priest. 10 The priest shall make an examination, and if there is a white swelling in the skin that has turned the hair white, and there is quick raw flesh in the swelling, 11 it is a chronic leprous disease in the skin of his body. The priest shall pronounce him unclean; he shall not confine him, for he is unclean. 12 But if the disease breaks out in the skin, so that it covers all the skin of the diseased person from head to foot, so far as the priest can see,

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?
