2 Chronicles 17:7
Also in the third year of his reign he sent to his princes, even to Ben-hail, and to Obadiah, and to Zechariah, and to Nethaneel, and to Michaiah, to teach in the cities of Judah. Also in the third year of his reign he sent to his princes, even to Ben-hail, and to Obadiah, and to Zechariah, and to Nethaneel, and to Michaiah, to teach in the cities of Judah.
In the third year of his reign Jehoshaphat sent his princes — Ben-hail, Obadiah, Zechariah, Nethaneel, and Michaiah — to teach in the cities of Judah. The princes did not go alone, for Levites accompanied them carrying the book of the law of the Lord, and from that book they taught the people throughout all the cities of Judah. The sending was a decided measure to correct wrongdoing and to prevent the influence of error and mistakes from being felt, rather than conniving at sin from natural affection for relatives and friends.
Instruction in God's law was arranged to guard the people against apostasy and rebellion, to keep them safe and loyal to God and to one another as loyal subjects living by its requirements. That teaching brought a religious revival throughout the kingdom, as the people earnestly sought to understand God's requirements and to put away sin and lessen transgression. Jehoshaphat's obedient course brought God's favor and prosperity to his rule, and the fear of the Lord fell upon the surrounding kingdoms so that they made no war against him.
The verse shows that those entrusted with responsibility should faithfully uphold righteous principles. It is the work God expects from His people living at the close of this earth's history, with determined effort to walk in the fear of the Lord and to live lives that will convince unbelievers of the power of the grace of Christ.
