'Clay' in the Bible

its legs of iron, its feet part of iron and part of clay.

Thou sawest till a stone was cut out without hands; and it smote the image upon its feet of iron and clay, and broke them to pieces.

Then was the iron, the clay, the brass, the silver, and the gold broken in pieces together, and they became like the chaff of the summer threshing-floors; and the wind carried them away, and no place was found for them. And the stone that smote the image became a great mountain, and filled the whole earth.

And whereas thou sawest the feet and toes, part of potter's clay, and part of iron, the kingdom shall be divided; but there shall be in it of the strength of the iron, forasmuch as thou sawest the iron mixed with miry clay.

And as the toes of the feet were part of iron and part of clay, the kingdom shall be partly strong and partly fragile.

And whereas thou sawest the iron mixed with miry clay, they shall mingle themselves with the seed of men; but they shall not cleave one to another, even as iron doth not mingle with clay.

Forasmuch as thou sawest that a stone was cut out of the mountain without hands, and that it broke in pieces the iron, the brass, the clay, the silver, and the gold, the great God hath made known to the king what shall come to pass hereafter. And the dream is certain, and the interpretation of it sure.
