2 Chronicles 21:5-9

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

6He followed the ways of the kings of Israel, as the house of Ahab had done, for he married a daughter of Ahab. He did evil in the eyes of the Lord.

7Nevertheless, because of the covenant the Lord had made with David, the Lord was not willing to destroy the house of David. He had promised to maintain a lamp for him and his descendants forever.

8In the time of Jehoram, Edom rebelled against Judah and set up its own king.

9So Jehoram went there with his officers and all his chariots. The Edomites surrounded him and his chariot commanders, but he rose up and broke through by night.
