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 the daughter of Ahab was his wife: and he did evil in the sight of Yhwh. 19Yet Yhwh would not destroy Judah for David his servant’s sake, as he promised him to give him alway a light, and to his children.1

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