Revelation 13:15-18

WNT(i) 15 And power was granted him to give breath to the statue of the Wild Beast, so that the statue of the Wild Beast could even speak and cause all who refuse to worship it to be put to death. 16 And he causes all, small and great, rich and poor, free men and slaves, to have stamped upon them a mark on their right hands or on their foreheads, 17 in order that no one should be allowed to buy or sell unless he had the mark--either the name of the Wild Beast or the number which his name represents. 18 Here is scope for ingenuity. Let people of shrewd intelligence calculate the number of the Wild Beast; for it indicates a certain man, and his number is 666.
