2 Chronicles 20:31-34

Thus Jehoshaphat reigned over Judah. He was thirty-five years old when he began to reign, and he reigned twenty-five years in Jerusalem. His mother’s name was Azubah the daughter of Shilhi. He walked in the way of Asa his father and did not turn aside from it, doing what was right in the sight of the LORD. The high places, however, were not taken away; the people had not yet set their hearts upon the God of their fathers. Now the rest of the acts of Jehoshaphat, from first to last, are written in the chronicles of Jehu the son of Hanani, which are recorded in the Book of the Kings of Israel.
