The efforts of the king in behalf of God and His law found no echo with the great majority of the people. Though the king was successful in preventing the worship of idols in public, his subjects knew how to deceive him. Josiah sent out his pious sympathizers to inspect the houses of the people, and he was satisfied with their report, that they had found no idols, not suspecting that the recreant people has fastened half an image on each wing of the doors, so that the inmates faced their household idols as they closed the door upon Josiah's inspectors.
