'Sword' in the Bible

He held seven stars in his right hand, and a sharp double-edged sword extended out of his mouth. His face shone like the sun shining at full strength.

"To the angel of the church in Pergamum write the following: "This is the solemn pronouncement of the one who has the sharp double-edged sword:

Therefore, repent! If not, I will come against you quickly and make war against those people with the sword of my mouth.

And another horse, fiery red, came out, and the one who rode it was granted permission to take peace from the earth, so that people would butcher one another, and he was given a huge sword.

So I looked and here came a pale green horse! The name of the one who rode it was Death, and Hades followed right behind. They were given authority over a fourth of the earth, to kill its population with the sword, famine, and disease, and by the wild animals of the earth.

If anyone is meant for captivity, into captivity he will go. If anyone is to be killed by the sword, then by the sword he must be killed. This requires steadfast endurance and faith from the saints.

and, by the signs he was permitted to perform on behalf of the beast, he deceived those who live on the earth. He told those who live on the earth to make an image to the beast who had been wounded by the sword, but still lived.

From his mouth extends a sharp sword, so that with it he can strike the nations. He will rule them with an iron rod, and he stomps the winepress of the furious wrath of God, the All-Powerful.

The others were killed by the sword that extended from the mouth of the one who rode the horse, and all the birds gorged themselves with their flesh.
