And the fourth kingdom shall be strong as iron, forasmuch as iron breaketh in pieces and subdueth all things; and as iron that crusheth all these, shall it break in pieces and crush.
King James Version (KJV):
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.
