Numbers 12:10

From the tabernacle — Not from the whole tabernacle, but from that part, whither it was come, to that part which was directly over the mercy — seat, where it constantly abode. Leprous — She, and not Aaron, either because she was chief in the transgression or because God would not have his worship interrupted or dishonoured, which it must have been if Aaron had been leprous. White — This kind of leprosy was the most virulent and incurable of all. It is true, when the leprosy began in a particular part, and thence spread itself over all the flesh by degrees, and at last made it all white, that was an evidence of the cure of the leprosy, Leviticus 13:12. But it was otherwise when one was suddenly smitten with this universal whiteness.
