13 mIt performs great signs, even nmaking fire come down from heaven to earth in front of people, 14and by the signs that it is allowed to work in the presence of
Or on behalf of
the beast pit deceives those who dwell on earth, telling them to make an image for the beast qthat was wounded by the sword and yet lived.
15And it was allowed to give breath to the image of the beast, so that the image of the beast might even speak and might cause those who would not rworship the image of the beast sto be slain.
