Revelation 13:15-17

Riverside(i) 15 Power was granted to it to give breath to the image of the Beast, so that the image of the Beast spoke and it caused all who did not worship the image of the Beast to be put to death. 16 It causes all, small and great, rich and poor, freemen and slaves, to have a mark put on their right hands or on their foreheads, 17 so that no one can buy or sell unless he has the mark — the name of the Beast or the number of his name.
