You saw the feet and toes made from iron and baked clay, and this indicates it will be a divided kingdom. It will have some of the strength of iron but mixed with clay.
Then in my vision that I had that night a fourth beast appeared. It was terrifying, frightening, and extremely powerful, with great iron teeth. It tore apart and ate up its victims, and then trampled on what was left. This beast was different from those that came before it, and it had ten horns.
And the dragon stood on the sea shore. Then I saw a beast rising out of the sea. He had ten horns and seven heads, with ten small crowns on his horns, and had blasphemous names on his heads.
The ten horns that you saw are ten kings who have not begun to reign yet. However, they will be given authority to reign as kings together with the beast for one hour.
