Clarke's Bible Commentary - 2 Kings 9:24
Verse 24. Drew a bow with his full strength] The marginal reading is correct: He filled his hand with a bow. That is, "He immediately took up his bow, set his arrow, and let fly." This is the only meaning of the passage. Between his arms] That is, between his shoulders; for he was now turned, and was flying from Jehu.
John Gill's Bible Commentary
Ver. 24. And Jehu drew a bow with his full strength , etc.] To give the arrow all the force he could; and smote Jehoram between his arms ; that is, between his shoulders, his back being turned to him, and the chariot an open one: and the arrow went out at his heart : quite through him: and he sunk down in his chariot ; and died immediately.
Matthew Henry Commentary
Verses 16-29 - Jehu was a man of eager spirit. The wisdom of God is seen in the choic of those employed in his work. But it is not for any man's reputatio 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 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 persiste in; but when it is repented of and forsaken, there is peace. Joram die 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 an misery by it.
