And whereas thou sawest the feet and toes, part of potters' clay, and part of iron, the kingdom shall be {x} divided; but there shall be in it of the strength of the iron, forasmuch as thou sawest the iron mixed with miry clay.

(x) They will have civil wars, and continual discords among themselves.

Wesley's Notes

2:41 Divided - Partly strong, and partly weak; the Roman kingdom was divided, partly by their civil wars, partly when conquered provinces and kingdoms cast off the Roman yoke, and set up king's of their own, and so the empire was divided into ten kingdoms or toes.

Scofield Reference Notes

[1] but there shall be

From the "head of gold" (Dan 2:38) to the "iron" of the "fourth kingdom" (Rome) there is deterioration in fineness, but increase of strength (Dan 2:40). Then comes the deterioration of the "fourth kingdom" in that very quality, strength.

(1) Deterioration by division: The kingdom is divided into two, the legs (Eastern and Western empires), and these are again divided into kingdoms, the number of which when the Stone smites the image will be ten toes, Dan 2:42; cf. Dan 7:23,24.

(2) Deterioration by admixture; the iron of the Roman imperium mixed with the clay of the popular will, fickle and easily moulded. This is precisely what has come to pass in the constitutional monarchies which, the Republic of France and the despotism of Turkey, cover the sphere of ancient Roman rule.

Jamieson-Fausset-Brown Bible Commentary

41-43. feet . toes . part . clay . iron-explained presently, "the kingdom shall be partly strong, partly broken" (rather, "brittle," as earthenware); and Da 2:43, "they shall mingle . with the seed of men," that is, there will be power (in its deteriorated form, iron) mixed up with that which is wholly of man, and therefore brittle; power in the hands of the people having no internal stability, though something is left of the strength of the iron [Tregelles]. Newton, who understands the Roman empire to be parted into the ten kingdoms already (whereas Tregelles makes them future), explains the "clay" mixture as the blending of barbarous nations with Rome by intermarriages and alliances, in which there was no stable amalgamation, though the ten kingdoms retained much of Rome's strength. The "mingling with the seed of men" (Da 2:44) seems to refer to Ge 6:2, where the marriages of the seed of godly Seth with the daughters of ungodly Cain are described in similar words. The reference, therefore, seems to be to the blending of the Christianized Roman empire with the pagan nations, a deterioration being the result. Efforts have been often made to reunite the parts into one great empire, as by Charlemagne and Napoleon, but in vain. Christ alone shall effect that.

Matthew Henry's Concise Commentary

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.
