'With The Sword' in the Bible

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

If any man is for captivity, into captivity he goeth: if any man shall kill with the sword, with the sword must he be killed. Here is the patience and the faith of the saints.

and the rest were killed with the sword of him that sat upon the horse, even the sword which came forth out of his mouth: and all the birds were filled with their flesh.
