King Jehoshaphat of Judah had people taught the law of YHVH

 7Then in the third year of his [Jehoshaphat] reign he sent his officials, Ben-hail, Obadiah, Zechariah, Nethanel and Micaiah, to teach in the cities of Judah; 8and with them the Levites, Shemaiah, Nethaniah, Zebadiah, Asahel, Shemiramoth, Jehonathan, Adonijah, Tobijah and Tobadonijah, the Levites; and with them Elishama and Jehoram, the priests. 9They taught in Judah, having the book of the law of YHVH with them; and they went throughout all the cities of Judah and taught among the people.

10Now the dread of YHVH was on all the kingdoms of the lands which were around Judah, so that they did not make war against Jehoshaphat. 11Some of the Philistines brought gifts and silver as tribute to Jehoshaphat; the Arabians also brought him flocks, 7,700 rams and 7,700 male goats. 12So Jehoshaphat grew greater and greater, and he built fortresses and store cities in Judah. 13He had large supplies in the cities of Judah, and warriors, valiant men, in Jerusalem. 14This was their muster according to their fathers’ households: of Judah, commanders of thousands, Adnah was the commander, and with him 300,000 valiant warriors; 15and next to him was Johanan the commander, and with him 280,000; 16and next to him Amasiah the son of Zichri, who volunteered for YHVH, and with him 200,000 valiant warriors; 17and of Benjamin, Eliada a valiant warrior, and with him 200,000 armed with bow and shield; 18and next to him Jehozabad, and with him 180,000 equipped for war. 19These are they who served the king, apart from those whom the king put in the fortified cities through all Judah.
