He teacheth my hands to war, so that a bow of steel is broken by mine arms. He teacheth my hands to war - The success which I have had in my military exercises I owe to the Divine help. How few of the conquerors of mankind can say so! And how few among those who call themselves Christian warriors dare to say so! War is as contrary to the spirit of Christianity as murder. Nothing can justify Christian nations in shedding each other's blood! All men should live in peace; all men might live in peace; and the nation that is first to break it is under a heavy curse.
A bow of steel is broken by mine arms - All the versions render this: "Thou hast made my arm like a brazen bow." A bow of steel is out of the question. In the days of David it is not likely that the method of making steel was known. The method of making brass out of copper was known at a very early period of the world; and the ancients had the art of hardening it, so as to work it into the most efficient swords. From his own account David was swift, courageous, and strong.
