15 Moreover the altar that was at Bethel, and the high place which Jeroboam the son of Nebat, who made Israel sin, had made, both that altar and the high place he broke down; and he burned the high place and crushed it to powder, and burned the wooden image.
Matthew Henry's Commentary on 2 Kings 23:15
Commentary on 2 Kings 23:15-24
(Read 2 Kings 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.
