Parallel
Daniel 2:40
Brenton's English Septuagint · Berean Standard Bible
and a fourth kingdom, which shall be strong as iron: as iron beats to powder and subdues all things, so shall it beat to powder and subdue.
Finally, there will be a fourth kingdom as strong as iron; for iron shatters and crushes all things, and like iron that crushes all things, it will shatter and crush all the others.
