Daniel 2:39-43

39But after you, there will arise another kingdom, inferior to yours.

Next, a third kingdom, one of bronze, will rule the whole earth.

40Finally, there will be a fourth kingdom as strong as iron; for iron shatters and crushes all things, and like iron that crushes all things, it will shatter and crush all the others. 41And just as you saw that the feet and toes were made partly of fired clay and partly of iron, so this will be a divided kingdom, yet some of the strength of iron will be in it—just as you saw the iron mixed with clay. 42And as the toes of the feet were partly iron and partly clay, so this kingdom will be partly strong and partly brittle. 43As you saw the iron mixed with clay, so the peoples1 will mix with one another but will not hold together any more than iron mixes with clay.
