2 Chronicles 21:5-10

5Jehoram was thirty-two years of age when he became king, and he reigned eight years in Jerusalem.

6He walked in the way of the kings of Israel, just as the house of Ahab had done (for he married the daughter of Ahab), and he did what was evil in the sight of the Lord.

7Yet the Lord would not destroy the house of David because of the covenant which He had made with David, and because He had promised to give a lamp to him and to his sons forever.

8In the days of Jehoram Edom revolted against the rule of Judah and set up a king over themselves.

9Then Jehoram crossed over [the Jordan River] with his commanders and all his chariots, and rose up by night and struck down the Edomites who were surrounding him and the commanders of the chariots.

10So Edom revolted against the rule of Judah to this day. Then Libnah revolted at the same time against Jehoram’s rule, because he had abandoned (turned away from) the Lord God of his fathers.
