1 Kings 22:41-43

41Jehoshaphat son of Asa began to rule over Judah in the fourth year of King Ahab’s reign in Israel.

42Jehoshaphat 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.

43Jehoshaphat was a good king, following the example 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 still offered sacrifices and burned incense there.
