Then was the iron, the clay, the brass, the silver, and the gold broken to pieces together, and became like the chaff of the summer threshing-floor - The word rendered "together" (כצרה kachădâh) our translators would seem to have understood as referring to "time;" to its being done simultaneously. The more literal interpretation, however, is, "as one;" that is, "they were beaten small as one," referring to identity of condition. They were all reduced to one indiscriminate mass; to such a mass that the original materials could no longer be distinguished, and would all be blown away together. The literal meaning of the word (חד chad used and חדה chădâh) is, "one," or "first." Ezra 4:8, "wrote a letter;" Ezra 5:13, "in the first year of Cyrus;" Ezra 6:2, "a roll;" Daniel 2:9; "there is but one decree for you;" Daniel 3:19, "heat the furnace one seven times hotter," etc. United with the preposition (כ k) it means "as one," like the Hebrew כאחד ke'echâd) - Ecclesiastes 11:6; 2 Chronicles 5:13; Ezra 2:64; Ezra 3:9; Isaiah 65:25. The phrase "chaff of the summer threshing-floors" refers to the mode of winnowing grain in the East. This was done in the open air, usually on an elevated place, by throwing the grain, when thrashed, into the air with a shovel, and the wind thus drove away the chaff. Such chaff, therefore, naturally became an emblem of anything that was light, and that would be easily dissipated. See the notes at Isaiah 30:24; Matthew 3:12.

And the wind carried them away, that no place was found for them - They were entirely dissipated like chaff. As that seems to have no longer any place, but is carried we know not where, so the figure here would denote an entire annihilation of the power to which it refers.

And the stone that smote the image became a great mountain, and filled the whole earth - The vision which was before the mind of the king as here represented was, that the stone which was cut out of the mountain was at first small, and that while he contemplated it, it swelled to larger dimensions, until it became an immense mountain - a mountain that filled the whole land. It was this which, perhaps more than anything else, excited his wonder, that a stone, at first of so small dimensions, should of itself so increase as to surpass the size of the mountain from which it was cut, until it occupied every place in view. Everything about it was so remarkable and unusual, that it was no wonder that he could not explain it. We have now gone over a description of the literal vision as it appeared to the mind of the monarch. Had it been left here, it is clear that it would have been of difficult interpretation, and possibly the true explanation might never have been suggested. We have, however, an exposition by Daniel, which leaves no doubt as to its design, and which was intended to carry the mind forward into some of the most important and remarkable events of history. A portion of his statement has been fulfilled; a part remains still unaccomplished, and a careful exposition of his account of the meaning of the vision will lead our thoughts to some of the most important historical events which have occurred in introducing the Christian dispensation, and to events still more important in the statement of what is yet to come.

The stone - became a great mountain - There is the kingdom אבן eben, of the stone, and the kingdom of the mountain. See at the end at the chapter.

Then was the iron, the clay, the brass, the silver, and the gold, broken to pieces together,.... The feet, the basis of the image, being broken, the whole body of it fell, and with its own weight was broken to pieces; an emblem this of the utter dissolution of all the monarchies and kingdoms of the earth, signified by these several metals:

and became like the chaff of the summer threshing floors; which is exceeding small and light:

and the wind carried them away, that no place was found for them; for the several metals, and the monarchies signified by them, which were no more: the allusion is to the manner of winnowing corn in the eastern countries upon mountains, when the chaff was carried away by the wind, and seen no more:

and the stone that smote the image became a great mountain, and filled the earth; Christ's kingdom, from small beginnings, has increased, and will more and more, until the whole earth is subject to it: this began to have its accomplishment in the first times of the Gospel, especially when the Roman empire, as Pagan, was destroyed by Constantine, and the kingdom of Christ was set up in it; and it received a further accomplishment at the time of the Reformation, when Rome Papal had a deadly blow given it, and the Gospel of Christ was spread in several nations and kingdoms; but it will receive its full accomplishment when both the eastern and western antichrists shall be destroyed, and the kingdoms of this world shall become the Lord's and his Christ's, Revelation 11:15.

Then was the iron, the clay, the brass, the silver, and the gold, broken to pieces together, and became like the chaff of the summer threshingfloors; and the wind carried them away, that no place was found for them: and the stone that smote the image became a great mountain, and filled the whole earth.

Margin mountain

A mountain is one of the bibical symbols of a kingdom. See Scofield Note: "Isa 2:2".

35. broken . together-excluding a contemporaneous existence of the kingdom of the world and the kingdom of God (in its manifested, as distinguished from its spiritual, phase). The latter is not gradually to wear away the former, but to destroy it at once, and utterly (2Th 1:7-10; 2:8). However, the Hebrew may be translated, "in one discriminate mass."

chaff-image of the ungodly, as they shall be dealt with in the judgment (Ps 1:4, 5; Mt 3:12).

summer threshing-floors-Grain was winnowed in the East on an elevated space in the open air, by throwing the grain into the air with a shovel, so that the wind might clear away the chaff.

no place . found for them-(Re 20:11; compare Ps 37:10, 36; 103:16).

became . mountain-cut out of the mountain (Da 2:45) originally, it ends in becoming a mountain. So the kingdom of God, coming from heaven originally, ends in heaven being established on earth (Re 21:1-3).

filled . earth-(Isa 11:9; Hab 2:14). It is to do so in connection with Jerusalem as the mother Church (Ps 80:9; Isa 2:2, 3).

2:31-45 This image represented the kingdoms of the earth, that should successively rule the nations, and influence the affairs of the Jewish church. 1. The head of gold signified the Chaldean empire, then in being. 2. The breast and arms of silver signified the empire of the Medes and Persians. 3. The belly and thighs of brass signified the Grecian empire, founded by Alexander. 4. The legs and feet of iron signified the Roman empire. The Roman empire branched into ten kingdoms, as the toes of these feet. Some were weak as clay, others strong as iron. Endeavours have often been used to unite them, for strengthening the empire, but in vain. The stone cut out without hands, represented the kingdom of our Lord Jesus Christ, which should be set up in the kingdoms of the world, upon the ruins of Satan's kingdom in them. This was the Stone which the builders refused, because it was not cut out by their hands, but it is become the head stone of the corner. Of the increase of Christ's government and peace there shall be no end. The Lord shall reign, not only to the end of time, but when time and days shall be no more. As far as events have gone, the fulfilling this prophetic vision has been most exact and undeniable; future ages shall witness this Stone destroying the image, and filling the whole earth.
