Daniel 2:34-35

2:34 You were watching as a stone was cut out, but not by human hands. It struck the statue on its iron and clay feet, breaking them in pieces. 2:35 Then the iron, clay, bronze, silver, and gold were broken in pieces without distinction and became like chaff from the summer threshing floors that the wind carries away. Not a trace of them could be found. But the stone that struck the statue became a large mountain that filled the entire earth.

Daniel 2:40-45

2:40 Then there will be a fourth kingdom, one strong like iron. Just like iron breaks in pieces and shatters everything, and as iron breaks in pieces all of these metals, so it will break in pieces and crush the others. 2:41 In that you were seeing feet and toes partly of wet clay and partly of iron, so this will be a divided kingdom. Some of the strength of iron will be in it, for you saw iron mixed with wet clay. 2:42 In that the toes of the feet were partly of iron and partly of clay, the latter stages of this kingdom will be partly strong and partly fragile. 2:43 And in that you saw iron mixed with wet clay, so people will be mixed with one another without adhering to one another, just as iron does not mix with clay. 2:44 In the days of those kings the God of heaven will raise up an everlasting kingdom that will not be destroyed and a kingdom that will not be left to another people. It will break in pieces and bring about the demise of all these kingdoms. But it will stand forever. 2:45 You saw that a stone was cut from a mountain, but not by human hands; it smashed the iron, bronze, clay, silver, and gold into pieces. The great God has made known to the king what will occur in the future. The dream is certain, and its interpretation is reliable.”
