2 Chronicles 20:31-34

So Jehoshaphat ruled over the land of Judah. He was thirty-five years old when he became king, and he reigned in Jerusalem twenty-five years. His mother was Azubah, the daughter of Shilhi. Jehoshaphat was a good king, following the ways of his father, Asa. He did what was pleasing in the LORD’s sight. During his reign, however, he failed to remove all the pagan shrines, and the people never fully committed themselves to follow the God of their ancestors. The rest of the events of Jehoshaphat’s reign, from beginning to end, are recorded in The Record of Jehu Son of Hanani, which is included in The Book of the Kings of Israel.
