Daniel 7:7-8

7After this I kept looking in the night visions, and behold, [I saw] a fourth beast (the Roman Empire), terrible and extremely strong; and it had huge iron teeth. It devoured and crushed and trampled down what was left with its feet. It was different from all the beasts that came before it, and it had ten horns (ten kings).

8While I was considering the horns, behold, there came up among them another horn, a little one, and three of the first horns were pulled up by the roots before it; and behold, in this horn were eyes like the eyes of a man and a mouth boasting of great things.
