King Joram of Israel had been badly wounded in the battle at Ramoth, trying to defend it against King Hazael and the Syrian army. Joram was now recovering in Jezreel, and King Ahaziah of Judah was there, visiting him. Meanwhile, Jehu was in Ramoth, making plans to kill Joram. He said to his officers, "If you want me to be king, then don't let anyone leave this town. They might go to Jezreel and tell Joram." Then Jehu got in his chariot and rode to Jezreel.
Joash was severely wounded during the battle, and as soon as the Syrians left Judah, two of his officials, Zabad and Jehozabad, decided to revenge the death of Zechariah. They plotted and killed Joash while he was in bed, recovering from his wounds. Joash was buried in Jerusalem, but not in the royal tombs.
