17 The watchman on the tower of Jezreel saw Jehu and his company approaching, so he shouted to Joram, "I see a company of troops coming!" "Send out a rider to ask if they are coming in peace," King Joram ordered. 18 So a horseman went out to meet Jehu and said, "The king wants to know if you are coming in peace." Jehu replied, "What do you know about peace? Fall in behind me!" The watchman called out to the king, "The messenger has met them, but he's not returning." 19 So the king sent out a second horseman. He rode up to them and said, "The king wants to know if you come in peace." Again Jehu answered, "What do you know about peace? Fall in behind me!" 20 The watchman exclaimed, "The messenger has met them, but he isn't returning either! It must be Jehu son of Nimshi, for he's driving like a madman."

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.
