7 Then in my vision that night, I saw a fourth beast-terrifying, dreadful, and very strong. It devoured and crushed its victims with huge iron teeth and trampled their remains beneath its feet. It was different from any of the other beasts, and it had ten horns. 8 As I was looking at the horns, suddenly another small horn appeared among them. Three of the first horns were torn out by the roots to make room for it. This little horn had eyes like human eyes and a mouth that was boasting arrogantly.

Commentary on Daniel 7:1-8
(Read Daniel 7:1-8)
This vision contains the same prophetic representations with Nebuchadnezzar's dream. The great sea agitated by the winds, represented the earth and the dwellers on it troubled by ambitious princes and conquerors. The four beasts signified the same four empires, as the four parts of Nebuchadnezzar's image. Mighty conquerors are but instruments of God's vengeance on a guilty world. The savage beast represents the hateful features of their characters. But the dominion given to each has a limit; their wrath shall be made to praise the Lord, and the remainder of it he will restrain.
