Israel's next 3 kings after Jehoshaphat; Jehoram, Ahaziah and Joash can all literally trace their failures as kings to being in alliance with the kings of Israel, and the one who laid the foundation, though he was a good king, was Jehoshaphat. Alliances matter, the company you keep matters, they can literally be the difference between success and failure. Lastly, the priest, Jehoiada, a lot to learn from his selflessness. His reward in the end was great, he was buried as a king with the other kings of Judah.
