2 Chronicles 17:1-13

1Jehoshaphat his son then became king in his place, and made his position over Israel firm. 2He placed troops in all the fortified cities of Judah, and set garrisons in the land of Judah and in the cities of Ephraim which Asa his father had captured.
3The Lord was with Jehoshaphat because he [1] followed the example of his father David’s earlier days and did not seek the Baals, 4but sought the God of his father, [1] followed His commandments, and did not act as Israel did. 5So the Lord established the kingdom in his [1] control, and all Judah brought tribute to Jehoshaphat, and he had great riches and honor. 6[1] He took great pride in the ways of the Lord and again removed the high places and the Asherim from Judah.
7Then in the third year of his 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 the Lord with them; and they went throughout all the cities of Judah and taught among the people.
10Now the dread of the Lord 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.
