2 Kings 8:16-20

Now in the fifth year of Joram the son of Ahab king of Israel, when Jehoshaphat was the king of Judah, Jehoram the son of Jehoshaphat king of Judah became king.

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

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

However, the Lord did not want to destroy Judah, for the sake of David His servant, since He had promised him to give him a lamp through his sons always.

In his days Edom broke away from the rule of Judah, and appointed a king over themselves.
