Daniel 2:32, 35
The head of the statue was pure gold, its chest and arms were silver, its belly and thighs were bronze, / 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.
