17 Now the watchman was standing on the tower in Jezreel, and he spied the company of Jehu as he came, and said, "I see a company." Joram said, "Take a horseman, and send to meet them, and let him say, 'Is it peace?'"

A watchman on the tower - These watchmen, fixed on elevated places and generally within hearing of each other, served as a kind of telegraphs, to communicate intelligence through the whole country. But, in some cases, it appears that the intelligence was conveyed by a horseman to the next stage, as in the case before us. At this time, when the armies were at Ramoth-gilead, they were, no doubt, doubly watchful to observe the state of the country, and to notice every movement. See on 2-Samuel 13:34 (note).
And there stood a watchman on the tower of Jezreel,.... Who could see afar off when an enemy was coming, and his business was to give notice of it; and especially he was now on his watch tower, because the king was there, and this was necessary for his safety:
and he spied the company of Jehu as he came, and said, I see a company; a troop of soldiers, though he did not know who they were, and to whom they belonged, whether they were Syrians or Israelites; which was reported to the king:
and Joram said, take an horseman, and send to meet them, and let him say, is it peace? he might fear some ill had befallen his army at Ramothgilead, and the Syrians had got the advantage of them; or they had made an irruption into his country, and were coming to attack him at Jezreel; or there was an insurrection among his own people.
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].
