Daniel 2:40-43

“And there will be a fourth kingdom, strong and hard as iron. It will shatter all things in its way. Like iron that breaks everything to pieces, it will crush and break all the other kingdoms. “The feet and toes you saw, partly of iron and partly of clay, represent a divided kingdom that will retain some of the iron’s strength, just as you saw the iron and the clay mixed together. That its feet and toes were partly iron and partly clay means that this kingdom will be both strong and fragile. And just as you saw the iron and the clay mingled together, so the people of this kingdom will seek to be united, but they will not bond any more than iron will permanently bond with clay.
