Daniel 2:43
King James Version (1769 Blayney revision, with Apocrypha) · Berean Standard Bible
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 (note: Cald. this with this), even as iron is not mixed with clay.
As you saw the iron mixed with clay, so the peoples will mix with one another but will not hold together any more than iron mixes with clay.
