'Signs' in the Bible

And he does great signs, even making fire come down from heaven on the earth before the eyes of men.

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.

For they are evil spirits, working signs; who go out even to the kings of all the earth, to get them together to the war of the great day of God, the Ruler of all.

And the beast was taken, and with him the false prophet who did the signs before him, by which they were turned from the true way who had the mark of the beast, and who gave worship to his image: these two were put living into the sea of ever-burning fire.
