Daniel 2:40

And the fourth kingdom - Represented in the image by the legs of iron, and the feet “part of iron, and part of clay,” Daniel 2:33. The first question which arises here is, what kingdom is referred to by this? In regard to this, there have been two leading opinions: one, that it refers to the Roman empire; the other, that it refers to the kingdoms or dynasties that immediately succeeded the reign of Alexander the Great; embracing the kingdoms of the Seleucidae and Lagidae, Syria, and Egypt - in the language of Prof. Stuart, who adopts this opinion, “that the legs and feet were symbols of that intermingled and confused empire which sprung up under the Grecian chiefs who finally succeeded him,” (Alexander the Great). - “Com. on Daniel,” p. 173. For the reasoning by which this opinion is supported, see Prof. Stuart, pp. 173-193. The common opinion has been, that the reference is to the Roman empire, and in support of this opinion the following conditions may be suggested:

(1) The obvious design of the image was to symbolize the succession of great monarchies, which would precede the setting up of the kingdom of the Redeemer, and which would have an important agency in preparing the world for that. The Roman empire was in itself too important, and performed too important an agency in preparing the world for that, to be omitted in such an enumeration.

(2) The kingdom here referred to was to be in existence at the time symbolized by the cutting of the stone out of the mountain, for, during the continuance of that kingdom, or under it, “the God of heaven was to set up a kingdom which should never be destroyed,” Daniel 2:44. But the kingdoms of the Seleucidae and the Lagidae - the “intermingled and confused empires that sprang up” after Alexander the Great - had ceased before that time, being superseded by the Roman.

(3) Unless the Roman power be represented, the symmetry of the image is destroyed, for it would make what was, in fact, one kingdom represented by two different metals - brass and iron. We have seen above that the Babylonian empire was represented appropriately by gold; the Medo-Persian by silver; and the Macedonian by brass. We have seen also, that in fact the empire founded by Alexander, and continued through his successors in Syria and Egypt, was in fact one kingdom, so spoken of by the ancients, and being in fact a “Greek” dynasty. If the appellation of “brass” belonged to that kingdom as a Greek kingdom, there is an obvious incongruity, and a departure from the method of interpreting the other portions of the image, in applying the term “iron” to any portion of that kingdom.

(4) By the application of the term “iron,” it is evidently implied that the kingdom thus referred to would be distinguished for “strength” - strength greater than its predecessors - as iron surpasses brass, and silver, and gold, in that quality. But this was not true of the confused reigns that immediately followed Alexander. They were unitedly weaker than the Babylonian and the Medo-Persian, and weaker than the empire of Alexander. out of which they arose. Compare Daniel 8:21. It was true, however, of the Roman power, that it was so much superior to all its predecessors in power, that it might well be represented by iron in comparison with brass, silver, and gold.

(5) The fourth monarchy represented in Nebuchadnezzars dream is evidently the same which is represented by the fourth beast in Daniel 7:7, Daniel 7:23, Daniel 7:25. But it will appear, from the exposition of that chapter, that the reference there is to the Roman empire. See the note at these passages. There can be no well-founded objection to this view on the ground that this kingdom was not properly a “succession” of the kingdom of Alexander, and did not occupy precisely the same territory. The same was true of each of the other kingdoms - the Medo-Persian and Macedonian. Yet while they were not, in the usual sense of the term, in the “successions,” they did, in fact, follow one after the other; and with such accessions as were derived from conquest, and from the hereditary dominions of the conquerors, they did occupy the same territory. The design seems to have been to give a representation of a series of great monarchies, which would be, in an important sense, universal monarchies, and which should follow each other before the advent of the Saviour. The Roman, in addition to what it possessed in the West, actually occupied in the East substantially the same territory as the Babylonian, the Medo-Persian, and the Macedonian, and, like them, it had all the claims which any ancient sovereignty had to the title of a universal monarchy; indeed no kingdom has ever existed to which this title could with more justice be applied.

Shall be strong as iron - It is scarcely necessary to observe that this description is applicable to the Roman power. In nothing was it more remarkable than its “strength;” for that irresistible power before which all other nations were perfectly weak. This characteristic of the Roman power is thus noticed by Mr. Gibbon: “The arms of the Republic, sometimes vanquished in battle, always victorious in war, advanced with rapid steps to the Euphrates, the Danube, the Rhine, and the ocean; and the images of gold, or silver, or brass, that might serve to represent the nations and their kings, were successively broken by the “iron” monarchy of Rome.” - “Dec. and Fall,” p. 642, Lond. ed. 1830, as quoted by Prof. Bush.

Forasmuch as iron breaketh in pieces and subdueth all things - Iron is the metal which is used, and always has been used, for the purpose here suggested. In the form of hammers, sledges, and cannon-balls, and, in general, in reference to the accomplishment of any purpose, by beating or battering, this has been found to be the most valuable of the metals. It is heavy, is capable of being easily wrought into desired shapes; is abundant; is susceptible of being made hard so as not to be itself bruised, and has therefore, all the properties which could be desired for purposes like this.

And as iron that breaketh all these - That is, all these things; to wit, everything. Nothing is able to stand before it; there is nothing which it cannot reduce to powder. There is some repetition here, but it is for the sake of emphasis.

Shall it break in pieces and bruise - Nothing could better characterize the Roman power than this. Everything was crushed before it. The nations which they conquered ceased to be kingdoms, and were reduced to provinces, and as kingdoms they were blotted out from the list of nations. This has been well described by Mr. Irving: “The Roman empire did beat down the constitution and establishment of all other kingdoms; abolishing their independence, and bringing them into the most entire subjection; humbling the pride, subjecting the will, using the property, and trampling upon the power and dignity of all other states. For by this was the Roman dominion distinguished from all the rest, that it was the work of almost as many centuries as those were of years; the fruit of a thousand battles in which million of men were slain. It made room for itself, as doth a battering-ram, by continual successive blows; and it ceased not to beat and bruise all nations, so long as they continued to offer any resistance.” - “Discourse on Daniel’s Visions,” p. 180.
