And in the days of these kings shall the God of heaven set up a kingdom, which shall never be destroyed: and the kingdom shall not be left to other people, but it shall break in pieces and consume all these kingdoms, and it shall stand for ever.

Wesley's Notes

2:44 In the days of these kings - While the iron kingdom stood, for Christ was born in the reign of Augustus Caesar. And this kingdom is not bounded by any limits, as worldly empires are, but is truly universal. And it shall be for ever, never destroyed or given to others, as the rest were.

King James Translators' Notes

Scofield Reference Notes

[1] and in the days

The passage fixes authoritatively the time relative to other predicted events, when the kingdom of the heavens will be set up. It will be "in the days of those kings," i.e. the days of the ten kings (cf. Dan 7:24-27 symbolized by the toes of the image. That condition did not exist at the advent of Messiah, nor was it even possible until the dissolution of the Roman empire, and the rise of the present national world system. See "Kingdom (O.T.)" Gen 1:26 Zech 12:8 "Kingdom (N.T.)" Lk 1:31-33 1Cor 15:28, See Scofield Note: "Mt 3:2" note (defining "kingdom of heaven"). Verse 45 repeats the method by which the kingdom will be set up. (Cf) See Scofield Note: "Dan 2:31" Ps 2:5 2:6 Zech 14:1-8 14:9.

Jamieson-Fausset-Brown Bible Commentary

44. in the days of these kings-in the days of these kingdoms, that is, of the last of the four. So Christianity was set up when Rome had become mistress of Judea and the world (Lu 2:1, &c.) [Newton]. Rather, "in the days of these kings," answers to "upon his feet" (Da 2:34); that is, the ten toes (Da 2:42), or ten kings, the final state of the Roman empire. For "these kings" cannot mean the four successional monarchies, as they do not coexist as the holders of power; if the fourth had been meant, the singular, not the plural, would be used. The falling of the stone on the image must mean, destroying judgment on the fourth Gentile power, not gradual evangelization of it by grace; and the destroying judgment cannot be dealt by Christians, for they are taught to submit to the powers that be, so that it must be dealt by Christ Himself at His coming again. We live under the divisions of the Roman empire which began fourteen hundred years ago, and which at the time of His coming shall be definitely ten. All that had failed in the hand of man shall then pass away, and that which is kept in His own hand shall be introduced. Thus the second chapter is the alphabet of the subsequent prophetic statements in Daniel [Tregelles].

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.
