'By the Sword' in the Bible

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.

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.
