17 In Jezreel, the sentinel standing on the tower spied the company of Jehu arriving, and said, "I see a company." Joram said, "Take a horseman; send him to meet them, and let him say, "Is it peace?' " 18 So the horseman went to meet him; he said, "Thus says the king, "Is it peace?' " Jehu responded, "What have you to do with peace? Fall in behind me." The sentinel reported, saying, "The messenger reached them, but he is not coming back." 19 Then he sent out a second horseman, who came to them and said, "Thus says the king, "Is it peace?' " Jehu answered, "What have you to do with peace? Fall in behind me." 20 Again the sentinel reported, "He reached them, but he is not coming back. It looks like the driving of Jehu son of Nimshi; for he drives like a maniac."

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.
