2 Chronicles 17:1-6

And Jehoshaphat his son reigned in his stead, and strengthened himself against Israel. And he placed forces 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 taken. And Jehovah was with Jehoshaphat, because he walked in the first ways of his father David, and sought not unto the Baalim, but sought to the God of his father, and walked in his commandments, and not after the doings of Israel. Therefore Jehovah established the kingdom in his hand; and all Judah brought to Jehoshaphat tribute; and he had riches and honor in abundance. And his heart was lifted up in the ways of Jehovah: and furthermore he took away the high places and the Asherim out of Judah.
