2 Kings 8:20-22

In his days Edom revolted from under the hand of Judah, and made a king over themselves. Then 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. So Edom revolted from under the hand of Judah unto this day. Then did Libnah revolt at the same time.
