Daniel 2:33–41
its legs were iron, and its feet were part iron and part clay. / As you watched, a stone was cut out, but not by human hands. It struck the statue on its feet of iron and clay, and crushed them. / Then the iron, clay, bronze, silver, and gold were shattered and became like chaff on the threshing floor in summer. The wind carried them away, and not a trace of them could be found. But the stone that had struck the statue became a great mountain and filled the whole earth.
