1 Kings 22:41-44

41And Jehoshaphat the son of Asa began to reign over Judah in the fourth year of Ahab king of Israel.

42Jehoshaphat was thirty-five years old when he began to reign; and he reigned twenty-five years in Jerusalem; and his mother's name was Azubah, the daughter of Shilhi.

43And he walked in all the way of Asa his father; he turned not aside from it, doing what was right in the sight of Jehovah. Only, the high places were not removed: the people offered and burned incense still on the high places.

44And Jehoshaphat was at peace with the king of Israel.
