Jehoram, the fifth king of Judah, was the eldest son and successor of Jehoshaphat. Jehoram was thirty two years old when he ascended the throne and he reigned for eight years. He began his reign in bloody fashion, slaying all his brothers so that there would be no challenge to his authority, perhaps prompted in his act by his wife Athaliah, daughter of Ahab, King of Israel.
He walked in 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 . Nevertheless, for the sake of his servant David, the LORD was not willing to destroy Judah. He had promised to maintain a lamp for David and his descendants forever.
(2 Kings 8:18-19)
Jehoram sank into gross idolatry, totally undoing the good work of his predecessors, and bring on the wrath of God. The Edomites revolted; the Philistines, Arabians and Ethiopians invaded the land carrying with them much treasure, along with Jehoram's wives and children (except Ahaziah); and he himself was struck with a disease of the bowels, which eventually led to his bowels being removed. He had been warned about this by the prophet Elijah.
Jehoram died wretchedly, in great pain, and was refused a place in the sepulcher of the kings. He was succeeded by his son Ahaziah.
