The authors of the Books of Kings criticized him for following the ways of his father. During his reign the Moabites revolted from under his authority (2 Kings 3:5-7). He united with Jehoshaphat in an attempt to revive maritime trade by the Red Sea, which proved a failure (2 Chronicles 20:35-37). His messengers, sent to consult the god of Ekron regarding his recovery from the effects of a fall from the roof-gallery of his palace, were met on the way by Elijah, who sent them back to tell the king that he would never rise from his bed (1 Kings 22:51; 2 Kings 1:18).
Guided by his idolatrous mother Athaliah, his reign was disastrous (2 Kings 8:24-29; 9:29). He joined his uncle Jehoram, king of Israel, in an expedition against Hazael, king of Damascus; but was wounded at the pass of Gur when attempting to escape, and had strength only to reach Megiddo, where he died (2 Kings 9:22-28). He is said to have reigned only one year.
Ahaziah, son of Jehoram, is mentioned in the Dan Stele, found in 1993 and 1994 during archeological excavations of the site of Laish.
