Because of the signs it was given power to perform on behalf of the first beast, it deceived the inhabitants of the earth. It ordered them to set up an image in honor of the beast who was wounded by the sword and yet lived.
The second beast was given power to give breath to the image of the first beast, so that the image could speak and cause all who refused to worship the image to be killed.
It also forced all people, great and small, rich and poor, free and slave, to receive a mark on their right hands or on their foreheads,
so that they could not buy or sell unless they had the mark, which is the name of the beast or the number of its name.
This calls for wisdom. Let the person who has insight calculate the number of the beast, for it is the number of a man. That number is 666.
