Parallel
Daniel 2:43
Brenton's English Septuagint · Berean Standard Bible
Whereas thou sawest the iron mixed with earthenware, they shall be mingled with the seed of men: but they shall not cleave together, as the iron does not mix itself with earthenware.
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.
