'Bow' in the Bible

Their arrows are sharp, and every bow is bent: the feet of their horses are like rock, and their wheels are like a rushing storm.

For they are in flight from the sharp sword, and the bent bow, and from the trouble of war.

Who sent out from the east one who is right wherever he goes? he gives the nations into his hands, and makes him ruler over kings; he gives them as the dust to his sword, as dry stems before the wind to his bow.
