'With The Sword' in the Bible

Repent; or else I will come to thee quickly, and will fight against them with the sword of my mouth.

He that leadeth into captivity shall go into captivity: he that killeth with the sword must be killed with the sword. Here is the patience and the faith of the saints.

And the remnant were slain with the sword of him that sat upon the horse, which sword proceedeth out of his mouth: and all the fowls were filled with their flesh.
