27 Ahaziah king of Judah saw what was going on and made his escape on the road toward Beth Haggan. Jehu chased him, yelling out, "Get him, too!" Jehu's troops shot and wounded him in his chariot on the hill up to Gur, near Ibleam. He was able to make it as far as Megiddo; there he died. 28 His aides drove on to Jerusalem. They buried him in the family plot in the City of David. 29 In the eleventh year of the reign of Joram son of Ahab, Ahaziah had become king of Judah.

Commentary on 2 Kings 9:16-29
(Read 2 Kings 9:16-29)
Jehu was a man of eager spirit. The wisdom of God is seen in the choice of those employed in his work. But it is not for any man's reputation to be known by his fury. He that has rule over his own spirit, is better than the mighty. Joram met Jehu in the portion of Naboth. The circumstances of events are sometimes ordered by Divine Providence to make the punishment answer to the sin, as face answers to face in a glass. The way of sin can never be the way of peace, Isaiah 57:21. What peace can sinners have with God? No peace so long as sin is persisted in; but when it is repented of and forsaken, there is peace. Joram died as a criminal, under the sentence of the law. Ahaziah was joined with the house of Ahab. He was one of them; he had made himself so by sin. It is dangerous to join evil-doers; we shall be entangled in guilt and misery by it.
