23:20 The priests - By this relation it appears, that after the departure of the king of Assyria, divers of the Israelites who had retired to other parts, and kept themselves out of the conqueror's hands, returned together with their priests to their own land, and to their old trade, worshipping idols; to whom, peradventure, they ascribed this their deliverance from that judgment which Jehovah had brought upon them.

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.
