And there stood a watchman on the tower in Jezreel, and he spied the company of Jehu as he came, and said, I see a company. And Joram said, Take an horseman, and send to meet them, and let him say, Is it peace?

Jamieson-Fausset-Brown Bible Commentary

17-24. there stood a watchman on the tower of Jezreel-The Hebrew palaces, besides being situated on hills had usually towers attached to them, not only for the pleasure of a fine prospect, but as posts of useful observation. The ancient watchtower of Jezreel must have commanded a view of the whole region eastward, nearly down to the Jordan. Beth-shan stands on a rising ground about six or seven miles below it, in a narrow part of the plain; and when Jehu and his retinue reached that point between Gilboa and Beth-shan, they could be fully descried by the watchman on the tower. A report was made to Joram in his palace below. A messenger on horseback was quickly despatched down into the plain to meet the ambiguous host and to question the object of their approach. "Is it peace?" We may safely assume that this messenger would meet Jehu at the distance of three miles or more. On the report made of his being detained and turned into the rear of the still advancing troops, a second messenger was in like manner despatched, who would naturally meet Jehu at the distance of a mile or a mile and a half down on the plain. He also being turned into the rear, the watchman now distinctly perceived "the driving to be like the driving of Jehu, the son of Nimshi; for he driveth furiously." The alarmed monarch, awakened to a sense of his impending danger, quickly summoned his forces to meet the crisis. Accompanied by Ahaziah, king of Judah, the two sovereigns ascended their chariots to make a feeble resistance to the impetuous onset of Jehu, who quickly from the plain ascended the steep northern sides of the site on which Jezreel stood, and the conflicting parties met "in the portion of Naboth the Jezreelite," where Joram was quickly despatched by an arrow from the strong arm of Jehu. We were impressed with the obvious accuracy of the sacred historian; the localities and distances being such as seem naturally to be required by the incidents related, affording just time for the transactions to have occurred in the order in which they are recorded [Howe].

Matthew Henry's Concise Commentary

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, Isa 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.
