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.
18 "If the body develops a boil in the skin, and it is healed, 19 and in the place of the boil there comes a white swelling or a bright spot, reddish-white, then it shall be shown to the priest; 20 and if, when the priest sees it, it indeed appears deeper than the skin, and its hair has turned white, the priest shall pronounce him unclean. It is a leprous sore which has broken out of the boil. 21 But if the priest examines it, and indeed there are no white hairs in it, and it is not deeper than the skin, but has faded, then the priest shall isolate him seven days; 22 and if it should at all spread over the skin, then the priest shall pronounce him unclean. It is a leprous sore. 23 But if the bright spot stays in one place, and has not spread, it is the scar of the boil; and the priest shall pronounce him clean. 24 "Or if the body receives a burn on its skin by fire, and the raw flesh of the burn becomes a bright spot, reddish-white or white, 25 then the priest shall examine it; and indeed if the hair of the bright spot has turned white, and it appears deeper than the skin, it is leprosy broken out in the burn. Therefore the priest shall pronounce him unclean. It is a leprous sore. 26 But if the priest examines it, and indeed there are no white hairs in the bright spot, and it is not deeper than the skin, but has faded, then the priest shall isolate him seven days. 27 And the priest shall examine him on the seventh day. If it has at all spread over the skin, then the priest shall pronounce him unclean. It is a leprous sore. 28 But if the bright spot stays in one place, and has not spread on the skin, but has faded, it is a swelling from the burn. The priest shall pronounce him clean, for it is the scar from the burn. 29 "If a man or woman has a sore on the head or the beard, 30 then the priest shall examine the sore; and indeed if it appears deeper than the skin, and there is in it thin yellow hair, then the priest shall pronounce him unclean. It is a scaly leprosy of the head or beard. 31 But if the priest examines the scaly sore, and indeed it does not appear deeper than the skin, and there is no black hair in it, then the priest shall isolate the one who has the scale seven days. 32 And on the seventh day the priest shall examine the sore; and indeed if the scale has not spread, and there is no yellow hair in it, and the scale does not appear deeper than the skin, 33 he shall shave himself, but the scale he shall not shave. And the priest shall isolate the one who has the scale another seven days. 34 On the seventh day the priest shall examine the scale; and indeed if the scale has not spread over the skin, and does not appear deeper than the skin, then the priest shall pronounce him clean. He shall wash his clothes and be clean. 35 But if the scale should at all spread over the skin after his cleansing, 36 then the priest shall examine him; and indeed if the scale has spread over the skin, the priest need not seek for yellow hair. He is unclean. 37 But if the scale appears to be at a standstill, and there is black hair grown up in it, the scale has healed. He is clean, and the priest shall pronounce him clean.
38 "If a man or a woman has bright spots on the skin of the body, specifically white bright spots, 39 then the priest shall look; and indeed if the bright spots on the skin of the body are dull white, it is a white spot that grows on the skin. He is clean. 40 As for the man whose hair has fallen from his head, he is bald, but 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?
Commentary on Leviticus 13:18-44
(Read Leviticus 13:18-44)
The priest is told what judgment to make, if there were any appearance of a leprosy in old sores; and such is the danger of those who having escaped the pollutions of the world are again entangled therein. Or, in a burn by accident, verse 24. The burning of strife and contention often occasions the rising and breaking out of that corruption, which proves that men are unclean. Human life lies exposed to many grievances. With what troops of diseases are we beset on every side; and thy all entered by sin! If the constitution be healthy, and the body lively and easy, we are bound to glorify God with our bodies. Particular note was taken of the leprosy, if in the head. If the leprosy of sin has seized the head; if the judgment be corrupted, and wicked principles, which support wicked practices, are embraced, it is utter uncleanness, from which few are cleansed. Soundness in the faith keeps leprosy from the head.
