2 Kings 8:16-24

Now in the fifth year of Joram the son of Ahab king of Israel, Jehoshaphat being then the king of Judah, Jehoram the son of Jehoshaphat king of Judah became king. He was thirty-two years old when he became king, and he reigned eight years in Jerusalem. He walked in the way of the kings of Israel, just as the house of Ahab had done, for the daughter of Ahab became his wife; and he did evil in the sight of the LORD. However, the LORD was not willing to destroy Judah, for the sake of David His servant, since He had promised him to give a lamp to him through his sons always. In his days Edom revolted from under the hand of Judah, and made a king over themselves. Then Joram crossed over to Zair, and all his chariots with him. And he arose by night and struck the Edomites who had surrounded him and the captains of the chariots; but his army fled to their tents. So Edom revolted against Judah to this day. Then Libnah revolted at the same time. The rest of the acts of Joram and all that he did, are they not written in the Book of the Chronicles of the Kings of Judah? So Joram slept with his fathers and was buried with his fathers in the city of David; and Ahaziah his son became king in his place.
