'Miry' in the Bible

And he brought me up out of the pit of destruction, out of the miry clay, and set my feet upon a rock; he hath established my goings:

And whereas thou sawest the feet and toes, part of potter's clay, and part of iron, the kingdom shall be divided; but there shall be in it of the strength of the iron, forasmuch as thou sawest the iron mixed with miry clay.

And whereas thou sawest the iron mixed with miry clay, they shall mingle themselves with the seed of men; but they shall not cleave one to another, even as iron doth not mingle with clay.
