word signifying to strike down or scourge, is applied to leprosy as a scourge of God, and in the case of men it always denotes the white leprosy, which the Arabs call baras. נגע, a stroke (lit., “stroke of leprosy”), is applied not only to the spot attacked by the leprosy, the leprous mole (Lev 13:3, Lev 13:29-32, Lev 13:42, etc.), but to the persons and even to things affected with leprosy (Lev 13:4, Lev 13:12, Lev 13:13, Lev 13:31, Lev 13:50, Lev 13:55).
Verse 3
A person so diseased was to be pronounced unclean, (a) if the hair of his head had turned white on the mole, i.e., if the dark hair which distinguished the Israelites had become white; and (b) if the appearance of the mole was deeper than the skin of the flesh, i.e., if the spot, where the mole was, appeared depressed in comparison with the rest of the skin. In that case it was leprosy. These signs are recognised by modern observers (e.g., Hensler); and among the Arabs leprosy is regarded as curable if the hair remains black upon the white spots, but incurable if it becomes whitish in colour.
verses 4-6
But if the bright spot was white upon the skin, and its appearance was not deeper than the skin, and the place therefore was not sunken, nor the hair turned white, the priest was to shut up the leper, i.e., preclude him from intercourse with other men, for seven days, and on the seventh day examine him again. If he then found that the mole still stood, i.e., remained unaltered, “in his eyes,” or in his view, that it had not spread any further, he was to shut him up for seven days more. And if, on further examination upon the seventh day, he found that the mole had become paler, had lost its brilliant whiteness, and had not spread, he was to declare him clean, for it was a scurf, i.e., a mere skin eruption, and not true leprosy. The person who had been pronounced clean, however, was to wash his clothes, to change himself from even the appearance of leprosy, and then to be clean.
verses 7-8
But if the scurf had spread upon the skin “after his (first) appearance before the priest with reference to his cleansing,” i.e., to be examined concerning his purification; and if the priest notice this on his second appearance, he was to declare him unclean, for in that case it was leprosy.
verses 9-17
The second case (Lev 13:9-17): if the leprosy broke out without previous eruptions.
verses 9-11
Lev 13:9-11 “If a mole of leprosy is in a man, and the priest to whom he is brought sees that there is a white rising in the skin, and this has turned the hair white, and there is raw (proud) flesh upon the elevation, it is an old
