Revelation 13:2, 7, 15-17

And the beast which I saw was like a leopard, and his feet were like those of a bear, and his mouth like the mouth of a lion. And the dragon gave him his power and his throne and great authority.

It was also given to him to make war with the saints and to overcome them, and authority over every tribe and people and tongue and nation was given to him.

And it was given to him to give breath to the image of the beast, so that the image of the beast would even speak and cause as many as do not worship the image of the beast to be killed. 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.
