2 Kings 8:16-19

Jehoram King of Judah 16In the fifth year of Joram son of Ahab king of Israel, when Jehoshaphat was king of Judah, Jehoram son of Jehoshaphat began his reign as king of Judah. 17He was thirty-two years old when he became king, and he reigned in Jerusalem eight years. 18He followed the ways of the kings of Israel, as the house of Ahab had done, for he married a daughter of Ahab. He did evil in the eyes of the LORD .

19Nevertheless, for the sake of his servant David, the LORD was not willing to destroy Judah. He had promised to maintain a lamp for David and his descendants forever.
