'Miry' in the Bible

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.

Rescue me from the miry mud; don’t let me sink.Let me be rescued from those who hate meand from the deep waters.

May burning coals fall on them; may they be cast into fire, and into miry pits, never to rise again.

But the miry places thereof and the marishes thereof shall not be healed; they shall be given to salt.

And whereas thou sawest the feet and toes, part of potters' 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 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 is not mixed with clay.
