'Sword' in the Bible

In His right hand He held seven stars, and out of His mouth came a sharp two-edged sword; and His face was like the sun shining in its strength.

“And to the angel of the church in Pergamum write:The One who has the sharp two-edged sword says this:

Therefore repent; or else I am coming to you quickly, and I will make war against them with the sword of My mouth.

And another, a red horse, went out; and to him who sat on it, it was granted to take peace from the earth, and that men would slay one another; and a great sword was given to him.

I looked, and behold, an ashen horse; and he who sat on it had the name Death; and Hades was following with him. Authority was given to them over a fourth of the earth, to kill with sword and with famine and with pestilence and by the wild beasts of the earth.

If anyone is destined for captivity, to captivity he goes; if anyone kills with the sword, with the sword he must be killed. Here is the perseverance and the faith of the saints.

And he deceives those who dwell on the earth because of the signs which it was given him to perform in the presence of the beast, telling those who dwell on the earth to make an image to the beast who *had the wound of the sword and has come to life.

From His mouth comes a sharp sword, so that with it He may strike down the nations, and He will rule them with a rod of iron; and He treads the wine press of the fierce wrath of God, the Almighty.

And the rest were killed with the sword which came from the mouth of Him who sat on the horse, and all the birds were filled with their flesh.
