Psalms 89:43

Thou hast also turned the edge of his sword - The arms and military prowess of thy people are no longer of any use to them; Thou art against them, and therefore they are fallen. In what a perilous and hopeless situation must that soldier be who, while defending his life against his mortal foe, has his sword broken, or its edge turned; or, in modern warfare, whose gun misses fire! The Gauls, when invaded by the Romans, had no method of hardening iron; at every blow their swords bended, so that they were obliged, before they could strike again, to put them under their foot or over their knee, to straighten them; and in most cases, before this could be done, their better armed foe had taken away their life! The edge of their sword was turned, so that they could not stand in battle; and hence the Gauls were conquered by the Romans.

Thou hast also turned the edge of his sword - That is, Thou hast turned it away, so that when it is raised to strike, it does not descend on the object aimed at by the blow. The meaning is, that he had not been successful in battle, or had been defeated.

And hast not made him to stand in the battle - To stand firm; to hold his ground. He has been driven back; his forces have fled.
