Matthew 24:29 “Immediately after the tribulation of those days the sun will be darkened, and the moon will not give its light, and the stars will fall from heaven, and the powers of the heavens will be shaken. Then will appear in heaven the sign of the Son of Man, and then all the tribes of the earth will mourn, and they will see the Son of Man coming on the clouds of heaven with power and great glory. And he will send out his angels with a loud trumpet call, and they will gather his elect from the four winds, from one end of heaven to the other.
Isaiah 13:10 For the stars of the heavens and their constellations will not give their light; the sun will be dark at its rising, and the moon will not shed its light.
Jeremiah 4:23-28 I looked on the earth, and behold, it was without form and void; and to the heavens, and they had no light. I looked on the mountains, and behold, they were quaking, and all the hills moved to and fro. I looked, and behold, there was no man, and all the birds of the air had fled. I looked, and behold, the fruitful land was a desert, and all its cities were laid in ruins before the LORD, before his fierce anger. For thus says the LORD, “The whole land shall be a desolation; yet I will not make a full end. “For this the earth shall mourn, and the heavens above be dark; for I have spoken; I have purposed; I have not relented, nor will I turn back.”
Ezekiel 32:7-8 When I blot you out, I will cover the heavens and make their stars dark; I will cover the sun with a cloud, and the moon shall not give its light. All the bright lights of heaven will I make dark over you, and put darkness on your land, declares the Lord GOD.
Joel 2:10 The earth quakes before them; the heavens tremble. The sun and the moon are darkened, and the stars withdraw their shining.
Joel 2:30-31 “And I will show wonders in the heavens and on the earth, blood and fire and columns of smoke. The sun shall be turned to darkness, and the moon to blood, before the great and awesome day of the LORD comes.
Amos 5:20 Is not the day of the LORD darkness, and not light, and gloom with no brightness in it?
Zephaniah 1:14-15 The great day of the LORD is near, near and hastening fast; the sound of the day of the LORD is bitter; the mighty man cries aloud there. A day of wrath is that day, a day of distress and anguish, a day of ruin and devastation, a day of darkness and gloom, a day of clouds and thick darkness,
Acts 2:19-20 And I will show wonders in the heavens above and signs on the earth below, blood, and fire, and vapor of smoke; the sun shall be turned to darkness and the moon to blood, before the day of the Lord comes, the great and magnificent day.
Revelation 6:12-17 When he opened the sixth seal, I looked, and behold, there was a great earthquake, and the sun became black as sackcloth, the full moon became like blood, and the stars of the sky fell to the earth as the fig tree sheds its winter fruit when shaken by a gale. The sky vanished like a scroll that is being rolled up, and every mountain and island was removed from its place. Then the kings of the earth and the great ones and the generals and the rich and the powerful, and everyone, slave and free, hid themselves in the caves and among the rocks of the mountains, calling to the mountains and rocks, “Fall on us and hide us from the face of him who is seated on the throne, and from the wrath of the Lamb, for the great day of their wrath has come, and who can stand?”
Several prophetic passages describe the cosmic disturbances that will precede and surround the glorious return of Jesus. All these signs are figures of great and terrible calamities. The roaring of the waves of the sea denotes great tumult and affliction among the people. “Perplexity” means doubt, anxiety; not knowing what to do to escape. “Men’s hearts should fail them for fear,” or by reason of fear. Their fears would be so great as to take away their courage and strength. Barnes)
But I am more inclinable to interpret them of the last judgment, and to think that our Saviour is now passed to satisfy the disciples about their other question, concerning the end of the world; for although Christ’s coming may sometimes signify that remarkable act of his providence in the destruction of his enemies, yet the next verses speaking of his coming with great power and glory, and of his coming with his angels, and with the sound of a trumpet, and gathering his elect from the four winds, the phrases are so like the phrases by which the Scripture expresses Christ’s coming to the last judgment, and Christ speaking to his disciples asking of him as well about that as the destruction of Jerusalem, I should rather interpret this verse with reference to the last judgment, than the destruction of Jerusalem before spoken of, or at least that these signs should be understood common both to the one and the other, as divers of the other signs mentioned in this chapter are. Some think that the darkening of the sun and the moon here, the falling of the stars, and the shaking of the powers of heaven, are to be taken metaphorically, as signifying the great change there should be in the ecclesiastical and civil state of the Jews; and it is true that such kind of expressions do often in Scripture so signify. But without doubt the literal sense is not to be excluded, whether we understand the text of the destruction of Jerusalem, or of his coming to his last judgment; for as historians tell of great prodigies seen before the former, so the apostle confirms us that there will be such things seen before the day of judgment.

There is no valid reason why the physical phenomena mentioned in this verso are not to be taken literally, even if we see also in them a spiritual significance. It is only reasonable to expect that the end of this world should be accompanied by stupendous changes in the realm of nature. The sun was miraculously darkened when Jesus hung on the cross. What wonder if similar catastrophes signal his coming to judgment? (unknown)
Men of the world scheme and plan for generation upon generation here, but they plan not with reference to the overwhelming, approaching, and most certain event of Christ’s second coming, which shall do away every human scheme, and set aside for ever all that God forbids. Christ here shows the state of the old world when the deluge came. They were secure and careless; they knew not, until the flood came; and they believed not. Did we know aright that all earthly things must shortly pass away, we should not set our eyes and hearts so much upon them as we do. The evil day is not the further off for men’s putting it far from them. What words can more strongly describe the suddenness of our Saviour’s coming! Men will be at their respective businesses, and suddenly the Lord of glory will appear. Women will be in their house employments, but in that moment every other work will be laid aside, and every heart will turn inward and say, It is the Lord! Am I prepared to meet him? Can I stand before him? And what, in fact, is the day of judgment to the whole world, but the day of death to every one who is not prepared for the return of Jesus Christ? (Henry)
