Daniel 2:40
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.
Berean Standard Bible
And the fourth kingdom shall be strong as iron: forasmuch as iron breaketh in pieces and subdueth all things: and as iron that breaketh all these, shall it break in pieces and bruise.
The fourth kingdom will be strong as iron, because iron breaks in pieces and subdues all things; and as iron that crushes all these, it will break in pieces and crush.
