Daniel 2:40-43

40Finally, there will be a fourth kingdom, strong as iron—for iron shatters and breaks everything—and just as iron smashes everything, so will it shatter and crush all the others.

41Just as you saw that the feet and toes were partly potter’s clay and partly iron, so this will be a divided kingdom. It will have some of the strength of the iron, for you saw the iron mixed with clay.

42As the toes of the feet were partly iron and partly clay, so this kingdom will be partly strong and partly brittle.

43Just as you saw iron mixed with clay, people will mix with one another, but they will not adhere to one another, just as iron does not mix with clay.
