'With The Sword' in the Bible

So repent, or else I will come to you quickly and make war upon them with the sword that is in my mouth.

Whoever is destined for captivity will go into captivity; whoever kills with the sword must be killed with the sword. On this fact rests the endurance and fidelity of God's people.

The rest were killed with the sword that came out of the mouth of him who sat on the horse, and all the birds gorged themselves upon their bodies.
