2 Chronicles 21:5-9

5Jehoram was thirty-two years old when he began to reign; and he reigned eight years in Jerusalem.

6And 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 Jehovah.

7But Jehovah would not destroy the house of David, because of the covenant that he had made with David, and as he had promised to give to him always a lamp, and to his sons.

8In his days Edom revolted from under the hand of Judah, and they set a king over themselves.

9And Jehoram went over with his captains, and all the chariots with him; and he rose up by night, and smote the Edomites who had surrounded him, and the captains of the chariots.
