NET

40 Then there will be a fourth kingdom, one strong like iron. Just like iron breaks in pieces and shatters everything, and as iron breaks in pieces all these metals, so it will break in pieces and crush the others.

Darby

40 And the fourth kingdom shall be strong as iron: forasmuch as iron breaketh in pieces and subdueth everything, and as iron that breaketh all these, so shall it break in pieces and bruise.

KJV

40 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.
