'Clay' in the Bible

Ye turn things upside down! Shall the potter be esteemed as clay; that the thing made should say of him that made it, He made me not; or the thing formed say of him that formed it, He hath no understanding?

I have raised up one from the north, and he is come; from the rising of the sun one that calleth upon my name: and he shall come upon rulers as upon mortar, and as the potter treadeth clay.

Woe unto him that striveth with his Maker! a potsherd among the potsherds of the earth! Shall the clay say to him that fashioneth it, What makest thou? or thy work, He hath no hands?

But now, O Jehovah, thou art our Father; we are the clay, and thou our potter; and we all are the work of thy hand.
