'Clay' in the Bible

How much less in them that dwell in houses of clay, whose foundation is in the dust, which are crushed before the moth?

Remember, I beseech thee, that thou hast made me as the clay; and wilt thou bring me into dust again?

Your remembrances are like unto ashes, your bodies to bodies of clay.

Though he heap up silver as the dust, and prepare raiment as the clay;

Behold, I am according to thy wish in God's stead: I also am formed out of the clay.

It is turned as clay to the seal; and they stand as a garment.
