23:15-24 Josiah's zeal extended to the cities of Israel within his reach. He carefully preserved the sepulchre of that man of God, who came from Judah to foretell the throwing down of Jeroboam's altar. When they had cleared the country of the old leaven of idolatry, then they applied themselves to the keeping of the feast. There was not holden such a passover in any of the foregoing reigns. The revival of a long-neglected ordinance, filled them with holy joy; and God recompensed their zeal in destroying idolatry with uncommon tokens of his presence and favour. We have reason to think that during the remainder of Josiah's reign, religion flourished.
17. What title is that that I see?—The king's attention probably, had been arrested by a tombstone more conspicuous than the rest around it, bearing on an inscription the name of him that lay beneath; and this prompted his curiosity to make the inquiry.
the men of the city—not the Assyrian colonists—for they could know nothing about the ancient transactions of the place—but some of the old people who had been allowed to remain, and perhaps the tomb itself might not then have been discoverable, through the effects of time and neglect, had not some "Old Mortality" garnished the sepulcher of the righteous.
