'Clay' in the Bible

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

Thou wast looking till that a stone hath been cut out without hands, and it hath smitten the image on its feet, that are of iron and of clay, and it hath broken them small;

then broken small together have been the iron, the clay, the brass, the silver, and the gold, and they have been as chaff from the summer threshing-floor, and carried them away hath the wind, and no place hath been found for them: and the stone that smote the image hath become a great mountain, and hath filled all the land.

As to that which thou hast seen: the feet and toes, part of them potter's clay, and part of them iron, the kingdom is divided: and some of the standing of the iron is to be in it, because that thou hast seen the iron mixed with miry clay.

As to the toes of the feet, part of them iron, and part of them clay: some part of the kingdom is strong, and some part of it is brittle.

Because thou hast seen iron mixed with miry clay, they are mixing themselves with the seed of men: and they are not adhering one with another, even as iron is not mixed with clay.

Because that thou hast seen that out of the mountain cut hath been a stone without hands, and it hath beaten small the iron, the brass, the clay, the silver, and the gold; the great God hath made known to the king that which is to be after this; and the dream is true, and its interpretation stedfast.
