2 Chronicles 17:9-12

And they taught in Judah, and had the book of the law of the LORD with them, and went about throughout all the cities of Judah, and taught the people. And the fear of the LORD fell upon all the kingdoms of the lands that were round about Judah, so that they made no war against Jehoshaphat. Also some of the Philistines brought Jehoshaphat presents, and tribute silver; and the Arabians brought him flocks, seven thousand and seven hundred rams, and seven thousand and seven hundred he goats. And Jehoshaphat waxed great exceedingly; and he built in Judah castles, and cities of store.
