Psalms 76:3

3.There he broke the arrows of the bow. We have here stated the particular way in which God was known in Judah. He was known by the wonderful proofs of his power, which he exhibited in preserving the city. Under these figures is described the destruction of the enemies of the chosen people. (268) They could not otherwise have been overthrown than by being despoiled of their armor and weapons of war. It is therefore said, that the arrows, the swords, and the shields, were broken, yea, all the implements of war; implying that these impious enemies of the Church were deprived of the power of doing harm. The fact indeed is, that they were wounded and slain, while their weapons remained uninjured; but this metonymy, by which what befell themselves is represented as happening to their implements of war, is not improper. Some translate the word רשפים, reshaphim, points of weapons! Properly, it should be renderedfires; (269) but it is more accurate to take it for arrows. Even birds are sometimes metaphorically so called, on account of their swiftness; and flying is attributed to arrows in Psalms 91:6
