'Signs' in the Bible

He also performs great signs, even causing fire to come down from heaven to earth in front of people.

He deceives those who live on the earth because of the signs that he is permitted to perform on behalf of the beast, telling those who live on the earth to make an image of the beast who had the sword wound and yet lived.

For they are spirits of demons performing signs, who travel to the kings of the whole world to assemble them for the battle of the great day of God, the Almighty.

But the beast was taken prisoner, and along with him the false prophet, who had performed the signs in his presence. He deceived those who accepted the mark of the beast and those who worshiped his image with these signs. Both of them were thrown alive into the lake of fire that burns with sulfur.
