'Great Things' in the Bible

While 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.

and the meaning of the ten horns (kings) that were on its head and the other horn which came up later, and before which three of the horns fell, specifically, that horn which had eyes and a mouth that boasted great things and which looked larger than the others.
