2 Kings 8:17-22

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

18He followed in the footsteps of the kings of Israel, just as Ahab’s dynasty had done, for he married Ahab’s daughter. He did evil in the sight of the Lord.

19But the Lord was unwilling to destroy Judah. He preserved Judah for the sake of his servant David to whom he had promised a perpetual dynasty.

20During his reign Edom freed themselves from Judah’s control and set up their own king.

21Joram crossed over to Zair with all his chariots. The Edomites, who had surrounded him, attacked at night and defeated him and his chariot officers. The Israelite army retreated to their homeland.

22So Edom has remained free from Judah’s control to this very day. At that same time Libnah also rebelled.
