The feet and toes you saw were a combination of iron and baked clay, showing that this kingdom will be divided. Like iron mixed with clay, it will have some of the strength of iron.
Following that kingdom, there will be a fourth one, as strong as iron. That kingdom will smash and crush all previous empires, just as iron smashes and crushes everything it strikes.
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.
Then I saw a beast rising up out of the sea. It had seven heads and ten horns, with ten crowns on its horns. And written on each head were names that blasphemed God.
The ten horns of the beast are ten kings who have not yet risen to power. They will be appointed to their kingdoms for one brief moment to reign with the beast.
