Daniel 2:40

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.

Daniel 2:40 Meaning and Commentary

Daniel 2:40

And the fourth kingdom shall be strong as iron
This is not the kingdom of the Lagidae and Seleucidae, the successors of Alexander, as some have thought; for these are designed by the thighs in the third kingdom; and, besides, the kingdom of Christ was to arise in the time of this fourth kingdom, which it did not in that; nor the kingdom of Gog, or the empire of the Turks, as Saadiah, Aben Ezra, and Jarchi; but the Roman empire, which is compared to iron for its strength, firmness, and duration in itself; and for its power over other nations; and also for its cruelty to the Jews above all others, in utterly destroying their city, temple, and nation: forasmuch as iron breaketh in pieces and subdueth all things;
so this kingdom has subdued and conquered all others; not the Jews only, but the Persians, Egyptians, Syrians, Africans, French, Germans, yea, all the world: and as iron that breaketh,
or "even as iron breaketh all these", shall it break in pieces, and bruise;
all nations and kingdoms; hence Rome has been called the mistress of the world, and its empire in Scripture is called the whole world, ( Luke 2:1 ) ( Revelation 17:18 ) .

Daniel 2:40 In-Context

38 Wherever the sons of men or beasts of the field or birds of the air dwell, He has given them into your hand and has made you ruler over them all. You are that head of gold.

39 But after you, there will arise another kingdom, inferior to yours. Next, a third kingdom, one of bronze, will rule the whole earth.

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.

41 And just as you saw that the feet and toes were made partly of fired clay and partly of iron, so this will be a divided kingdom, yet some of the strength of iron will be in it—just as you saw the iron mixed with clay.

42 And as the toes of the feet were partly iron and partly clay, so this kingdom will be partly strong and partly brittle.
