During Jehoram's reign, Edom revolted against Judah's rule and set up their own king.
Jehoram responded by taking his army of chariots to Zair. Edom surrounded him, but in the middle of the night he and his charioteers broke through the lines and hit Edom hard. But his infantry deserted him.
Edom continues in revolt against Judah right up to the present. Even little Libnah revolted at that time.
The rest of the life and times of Jehoram, the record of his rule, is written in The Chronicles of the Kings of Judah.
Jehoram died and was buried in the family grave in the City of David. His son Ahaziah succeeded him as king.
In the twelfth year of the reign of Joram son of Ahab king of Israel, Ahaziah son of Jehoram king of Judah began his reign.
Ahaziah was twenty-two years old when he became king; he ruled only a year in Jerusalem. His mother was Athaliah, granddaughter of Omri king of Israel.
He lived and ruled just like the Ahab family had done, continuing the same evil-in-God's-sight line of sin, related by both marriage and sin to the Ahab clan.
He joined Joram son of Ahab king of Israel in a war against Hazael king of Aram at Ramoth Gilead. The archers wounded Joram.
Joram pulled back to Jezreel to convalesce from the injuries he had received in the fight with Hazael. Ahaziah son of Jehoram king of Judah paid a visit to Joram son of Ahab on his sickbed in Jezreel.
