'Means' in the Bible

I looked and a pale-colored horse appeared. Its rider's name was Death, and Hades came close behind him; and authority was given to them over the fourth part of the earth, to kill with the sword or with famine or pestilence or by means of the wild beasts of the earth.

For the power of the horses [to do harm] is in their mouths and in their tails; for their tails are like serpents and have heads, and it is with them that they do harm.

And they overcame and conquered him because of the blood of the Lamb and because of the word of their testimony, for they did not love their life and renounce their faith even when faced with death.

And deceiveth them that dwell on the earth by the means of those miracles which he had power to do in the sight of the beast; saying to them that dwell on the earth, that they should make an image to the beast, which had the wound by a sword, and did live.
