Revelation 13:11, 14, 16-17

Then I saw another beast come up out of the earth. He had two horns like those of a lamb, but he spoke with the voice of a dragon.

And with all the miracles he was allowed to perform on behalf of the first beast, he deceived all the people who belong to this world. He ordered the people to make a great statue of the first beast, who was fatally wounded and then came back to life.

He required everyone—small and great, rich and poor, free and slave—to be given a mark on the right hand or on the forehead. And no one could buy or sell anything without that mark, which was either the name of the beast or the number representing his name.
