Revelation 13:11, 14, 16-17

Then I saw another beast coming up out of the earth; and he had two horns like a lamb and he spoke as a dragon.

And he deceives those who dwell on the earth because of the signs which it was given him to perform in the presence of the beast, telling those who dwell on the earth to make an image to the beast who *had the wound of the sword and has come to life.

And he causes all, the small and the great, and the rich and the poor, and the free men and the slaves, to be given a mark on their right hand or on their forehead, and he provides that no one will be able to buy or to sell, except the one who has the mark, either the name of the beast or the number of his name.
