The short and bitter reign of Ahazya son of Ahav is characterized by sin and failure. He surpasses the evil of his father by becoming personally involved in idol worship. As a leader, his partnership with Yehoshafat fails, and Moav rebels from under Israelite control. He falls ill and dies with no son to take the throne from him. The narrative is described through the sending of messengers by Ahazya.
