Daniel 2:43

And whereas thou sawest iron mixed with miry clay, they, the rulers and the various ruling elements making up the fourth kingdom, shall mingle themselves with the seed of men, making an effort to establish harmony; but they shall not cleave one to another, in a firmly coherent mass, even as iron is not mixed with clay, namely, in a solid and permanent union.

The world-power in its totality appears as a colossal human form: Babylon, the head of gold; Medo-Persia, the breast and the two arms of silver; the Greco-Macedonian Empire, as the belly and the two thighs of brass; and Rome, with its various branches and dependent kingdoms, as the legs of iron and the feet of iron and clay. "Those kingdoms only are mentioned which stand in some relation to the Lord's people. "
