'Clay' in the Bible

its legs of iron, its feet partly of iron and partly of clay [pottery].

As you were looking, a stone was cut out without [human] hands, and it struck the statue on its feet of iron and clay and crushed them.

Then the iron, the clay, the bronze, the silver, and the gold were crushed together and became like the chaff from the summer threshing floors; and the wind carried them away so that not a trace of them could be found. And the stone that struck the statue became a great mountain and filled the whole earth.

And as you saw the feet and toes, partly of potter’s clay and partly of iron, it will be a divided kingdom; but there will be in it some of the durability and strength of iron, just as you saw the iron mixed with common clay.

As the [ten] toes of the feet were partly of iron and partly of clay, so some of the kingdom will be strong, and another part of it will be brittle.

And as you saw the iron mixed with common clay, so they will combine with one another in the seed of men; but they will not merge [for such diverse things or ideologies cannot unite], even as iron does not mix with clay.

Just as you saw that a stone was cut out of the mountain without hands and that it crushed the iron, the bronze, the clay, the silver and the gold, the great God has revealed to the king what will take place in the future; so the dream is true and its interpretation is trustworthy.”
