'Miry' in the Bible

He brought me up out of a horrible pit [of tumult and of destruction], out of the miry clay,And He set my feet upon a rock, steadying my footsteps and establishing my path.

And as you saw the feet and toes, partly of potter’s clay and partly of iron, it will be a divided kingdom; but there will be in it some of the durability and strength of iron, just as you saw the iron mixed with common clay.

And as you saw the iron mixed with common clay, so they will combine with one another in the seed of men; but they will not merge [for such diverse things or ideologies cannot unite], even as iron does not mix with clay.
