'By the Sword' in the Bible

They were stoned, they were sawed in two, they died by the sword, they wandered about in sheepskins, in goatskins, destitute, afflicted, and mistreated.

And I looked, and there was a pale green horse. The horseman on it was named Death, and Hades was following after him. Authority was given to them over a fourth of the earth, to kill by the sword, by famine, by plague, and by the wild animals of the earth.
