Then was the iron, the clay, the brass, the silver, and the gold, broken to pieces together, and became like the chaff of the summer threshingfloors; and the wind carried them away, that no place was found for them: and the stone that smote the image became a great mountain, and filled the whole earth.
Nebuchadnezzar worshipped images, so God sent him a dream of a great statue to show him what his idols truly were: mere dreams, creatures of fancy that cost treasure and labor but signified nothing. The King had shown kindness to this poor prophet, and now received a prophet's reward that no money could buy.
