2 Chronicles 20:31-37

That about sums up Jehoshaphat’s reign over Judah. He was thirty-five years old when he became king and ruled as king in Jerusalem for twenty-five years. His mother was Azubah daughter of Shilhi. He continued the kind of life characteristic of his father Asa—no detours, no dead-ends—pleasing GOD with his life. But he failed to get rid of the neighborhood sex-and-religion shrines—people continued to pray and worship at these idolatrous god shops. The rest of Jehoshaphat’s life, from start to finish, is written in the memoirs of Jehu son of Hanani, which are included in the Royal Annals of Israel’s Kings. Late in life Jehoshaphat formed a trading syndicate with Ahaziah king of Israel—which was very wrong of him to do. He went in as partner with him to build ocean-going ships at Ezion Geber to trade with Tarshish. Eliezer son of Dodavahu of Mareshah preached against Jehoshaphat’s venture: “Because you joined forces with Ahaziah, GOD has shipwrecked your work.” The ships were smashed and nothing ever came of the trade partnership.
