Revelation 13:15-17

New Revised Standard Version Catholic Edition

¹⁵ and it was allowed to give breath^[a] to the image of the beast so that the image of the beast could even speak and cause those who would not worship the image of the beast to be killed. ¹⁶ Also it causes all, both small and great, both rich and poor, both free and slave, to be marked on the right hand or the forehead, ¹⁷ so that no one can buy or sell who does not have the mark, that is, the name of the beast or the number of its name.
