'By the Sword' in the Bible

And ye shall chase your enemies, and they shall fall before you by the sword.

And five of you shall chase an hundred, and an hundred of you shall put ten thousand to flight: and your enemies shall fall before you by the sword.

"As for the remnants among you, I'll bring despair in their hearts in the land of their enemies so that even the sound of a blown leaf will chase them and they flee as though pursued by the sword and fall when no one is pursuing.
