And the stars of heaven shall fall, and the powers that are in heaven shall be shaken.

Jamieson-Fausset-Brown Bible Commentary

25. And the stars of heaven shall fall-"and upon the earth distress of nations, with perplexity; the sea and the waves roaring; men's hearts failing them for fear, and for looking after those things which are coming on the earth" (Lu 21:25, 26).

and the powers that are in heaven shall be shaken-Though the grandeur of this language carries the mind over the head of all periods but that of Christ's Second Coming, nearly every expression will be found used of the Lord's coming in terrible national judgments: as of Babylon (Isa 13:9-13); of Idumea (Isa 34:1, 2, 4, 8-10); of Egypt (Eze 32:7, 8); compare also Ps 18:7-15; Isa 24:1, 17-19; Joe 2:10, 11, &c. We cannot therefore consider the mere strength of this language a proof that it refers exclusively or primarily to the precursors of the final day, though of course in "that day" it will have its most awful fulfilment.

Matthew Henry's Concise Commentary

13:24-27 The disciples had confounded the destruction of Jerusalem and the end of the world. This mistake Christ set right, and showed that the day of Christ's coming, and the day of judgment, shall be after that tribulation. Here he foretells the final dissolution of the present frame and fabric of the world. Also, the visible appearance of the Lord Jesus coming in the clouds, and the gathering together of all the elect to him.

Matthew Henry's Whole Bible Commentary

Verses 24-27

These verses seem to point at Christ's second coming, to judge the world; the disciples, in their question, had confounded the destruction of Jerusalem and the end of the world (Mt. 24:3), which was built upon a mistake, as if the temple must needs stand as long as the world stands; this mistake Christ rectifies, and shows that the end of the world in those days, those other days you enquire about, the day of Christ's coming, and the day of judgment, shall be after that tribulation, and not coincident with it. Let those who live to see the Jewish nation destroyed, take heed of thinking that, because the Son of man doth not visibly come in the clouds then, he will never so come; no, he will come after that. And here he foretels,

1. The final dissolution of the present frame and fabric of the world; even of that part of it which seems least liable to change, the upper part, the pure and more refined part; The sun shall be darkened, and the moon shall no more give her light; for they shall be quite outshone by the glory of the Son of man, Isa. 24:23. The stars of heaven, that from the beginning had kept their place and regular motion, shall fall as leaves in autumn; and the powers that are in heaven, the heavenly bodies, the fixed stars, shall be shaken.

2. The visible appearance of the Lord Jesus, to whom the judgment of that day shall be committed (v. 26); Then shall they see the Son of man coming in the clouds. Probably he will come over that very place where he sat when he said this; for the clouds are in the lower region of the air. He shall come with great power and glory, such as will be suited to the errand on which he comes. Every eye shall then see him.

3. The gathering together of all the elect to him (v. 27); He shall send his angels, and gather together his elect to him, to meet him in the air, 1 Th. 4:17. They shall be fetched from one end of the world to the other, so that none shall be missing from that general assembly; they shall be fetched from the uttermost part of the earth, most remote from the places where Christ's tribunal shall be set, and shall be brought to the uttermost part of heaven; so sure, so swift, so easy, shall their conveyance be, that there shall none of them miscarry, though they were to be brought from the uttermost part of the earth one way, to the uttermost part of the heaven another way. A faithful Israelite shall be carried safely, though it were from the utmost border of the land of bondage to the utmost border of the land of promise.
