"The second beast was permitted to give life to the image of the first beast, so that the image of the beast could even speak and cause all who would not worship the image of the beast to be killed. He also causes all—the small and the great, the rich and the poor, the free and the slave—to receive a mark on their right hand or upon their forehead. And so no one can buy or sell unless he has the mark—either the name of the beast or the number of his name,"

(Revelation 13:15-17).
