2 Kings 8:17-22

17Thirty and two years old was he when he began to reign; and he reigned eight years in Jerusalem. 18And he walked in the way of the kings of Israel, as did the house of Ahab: for he had the daughter of Ahab to wife; and he did that which was evil in the sight of Jehovah. 19Howbeit Jehovah would not destroy Judah, for David his servant’s sake, as he promised him to give unto him a lamp for his children alway.

20In his days Edom revolted from under the hand of Judah, and made a king over themselves. 21Then Joram passed over to Zair, and all his chariots with him: and he rose up by night, and smote the Edomites that compassed him about, and the captains of the chariots; and the people fled to their tents. 22So Edom revolted from under the hand of Judah unto this day. Then did Libnah revolt at the same time.
