2 Kings 8:17-22

17He was thirty-two years old when he became king, and he reigned eight years in Jerusalem.

18And he walked in the way of the kings of Israel, just as the house of Ahab had done, for the daughter of Ahab was his wife; and he did evil in the sight of the Lord.

19Yet the Lord would not destroy Judah, for the sake of His servant David, as He promised him to give a lamp to him and his sons forever.

20In his days Edom revolted against Judah’s authority, and made a king over themselves.

21So Joram went to Zair, and all his chariots with him. Then he rose by night and attacked the Edomites who had surrounded him and the captains of the chariots; and the troops fled to their tents.

22Thus Edom has been in revolt against Judah’s authority to this day. And Libnah revolted at that time.
