'Clay' in the Bible

The words of Yahweh are flawless words, as silver refined in a clay furnace, purified seven times.

I grind them as fine windblown dust; I beat them underfoot like clay in the streets.

My strength is dried up like baked clay;my tongue sticks to the roof of my mouth.You put me into the dust of death.

He brought me up also out of an horrible pit, out of the miry clay, and set my feet upon a rock, and established my goings.

Before your clay pots are placed on a fire of burning thorns whether green or ablaze wrath will sweep them away like a storm.

For he knows what we are made of; he realizes we are made of clay.
