'By the Sword' in the Bible

then put the inhabitants of the town to death by the sword. Devote everything in it to divine destruction even its livestock by the sword.

The Lord your God will deliver it over to you and you must kill every single male by the sword.

Outside they will be cut off by the sword, and in the inner rooms by fear; death will take the young man and the virgin, the baby at the breast and the grey-haired man.
