Daniel 2:40

40 And then there will be a fourth empire, as strong as iron, which shatters and breaks everything. And just as iron shatters everything, it will shatter and crush all the earlier empires.

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 He has made you ruler of all the inhabited earth and ruler over all the animals and birds. You are the head of gold.

39 After you there will be another empire, not as great as yours, and after that a third, an empire of bronze, which will rule the whole earth.

40 And then there will be a fourth empire, as strong as iron, which shatters and breaks everything. And just as iron shatters everything, it will shatter and crush all the earlier empires.

41 You also saw that the feet and the toes were partly clay and partly iron. This means that it will be a divided empire. It will have something of the strength of iron, because there was iron mixed with the clay.

42 The toes - partly iron and partly clay - mean that part of the empire will be strong and part of it weak.
