'By the Sword' in the Bible

Repent! But if not I will come to you quickly, and will fight with them by the sword of My mouth.

And I looked, and behold, a pale green horse, and the one seated on it {was named} Death, and Hades followed after him. And authority was granted to them over a fourth of the earth, to kill by the sword and by famine and by pestilence and by the wild beasts of the earth.

Let anyone who has an ear listen: ??10 Whoever is destined for captivity, to captivity he goes: whoever kills with the sword, by the sword must he be killed. This is what shows the patience and the faith of the saints.

If anyone [is going] into captivity, into captivity he goes. If anyone [is] to be killed by the sword, by the sword he [is] to be killed. Here is the patient endurance and the faith of the saints.

And those who are on the earth are turned from the true way by him through the signs which he was given power to do before the beast; giving orders to those who are on the earth to make an image to the beast, who was wounded by the sword, and came to life.

And the rest were killed by the sword of the one who is seated on the horse--the [sword] that comes out of his mouth--and all the birds gorged themselves on their flesh.
