18 "When a person has a boil and it heals 19 and in place of the boil there is white swelling or a reddish-white shiny spot, the person must present himself to the priest 20 for an examination. If it looks like it has penetrated the skin and the hair in it has turned white, the priest will pronounce him unclean. It is a serious skin disease that has broken out in the boil. 21 But if the examination shows that there is no white hair in it and it is only skin deep and has faded, the priest will put him in quarantine for seven days. 22 If it then spreads over the skin, the priest will diagnose him as unclean. It is infectious. 23 But if the shiny spot has not changed and hasn't spread, it's only a scar from the boil. The priest will pronounce him clean. 24 "When a person has a burn on his skin and the raw flesh turns into a reddish-white or white shiny spot, 25 the priest is to examine it. If the hair has turned white in the shiny spot and it looks like it's more than skin deep, a serious skin disease has erupted in the area of the burn. The priest will pronounce him unclean; it is a serious skin disease and infectious. 26 But if on examination there is no white hair in the shiny spot and it doesn't look to be more than skin deep but has faded, the priest will put him in quarantine for seven days. 27 On the seventh day the priest will reexamine him. If by then it has spread over the skin, the priest will diagnose him as unclean; it is a serious skin disease and infectious. 28 If by that time the shiny spot has stayed the same and has not spread but has faded, it is only a swelling from the burn. The priest will pronounce him clean; it's only a scar from the burn. 29 "If a man or woman develops a sore on the head or chin, 30 the priest will offer a diagnosis. If it looks as if it is under the skin and the hair in it is yellow and thin, he will pronounce the person ritually unclean. It is an itch, an infectious skin disease. 31 But if when he examines the itch, he finds it is only skin deep and there is no black hair in it, he will put the person in quarantine for seven days. 32 On the seventh day he will reexamine the sore; if the itch has not spread, there is no yellow hair in it, and it looks as if the itch is only skin deep, 33 the person must shave, except for the itch; the priest will send him back to quarantine for another seven days. 34 If the itch has not spread, and looks to be only skin deep, the priest will pronounce him clean. The person can go home and wash his clothes; he is clean. 35 But if the itch spreads after being pronounced clean, 36 the priest must reexamine it; if the itch has spread in the skin, he doesn't have to look any farther, for yellow hair, for instance; he is unclean. 37 But if he sees that the itch is unchanged and black hair has begun to grow in it, the itch is healed. The person is clean and the priest will pronounce him clean.

38 "When a man or woman gets shiny or white shiny spots on the skin, 39 the priest is to make an examination; if the shiny spots are dull white, it is only a rash that has broken out: The person is clean. 40 "When a man loses his hair and goes bald, he is clean. 41 If he loses his hair from his forehead, he is bald and he is clean. 42 But if he has a reddish-white sore on scalp or forehead, it means a serious skin disease is breaking out. 43 The priest is to examine it; if the swollen sore on his scalp or forehead is reddish-white like the appearance of the sore of a serious skin disease, 44 he has a serious skin disease and is unclean. The priest has to pronounce him unclean because of the sore on his head.

Matthew Henry's Commentary on Leviticus 13:18-44

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.
