Matthew 24:29 is repeated in Revelation chapter 6, with the Second Coming of Christ at the end of the chapter.
Why would the characters be hiding from the wrath of the Lamb unless the Lamb is present at that point in time? Five of these same characters are found in chapter 19.
Mat 24:29 Immediately after the tribulation of those days shall the sun be darkened, and the moon shall not give her light, and the stars shall fall from heaven, and the powers of the heavens shall be shaken:
Mat 24:30 And then shall appear the sign of the Son of man in heaven: and then shall all the tribes of the earth mourn, and they shall see the Son of man coming in the clouds of heaven with power and great glory.
Mat 24:31 And he shall send his angels with a great sound of a trumpet, and they shall gather together his elect from the four winds, from one end of heaven to the other.
Rev 6:12 And I beheld when he had opened the sixth seal, and, lo, there was a great earthquake; and the sun became black as sackcloth of hair, and the moon became as blood;
Rev 6:13 And the stars of heaven fell unto the earth, even as a fig tree casteth her untimely figs, when she is shaken of a mighty wind.
Rev 6:14 And the heaven departed as a scroll when it is rolled together; and every mountain and island were moved out of their places.
Rev 6:15 And the kings of the earth, and the great men, and the rich men, and the chief captains, and the mighty men, and every bondman, and every free man, hid themselves in the dens and in the rocks of the mountains;
Rev 6:16 And said to the mountains and rocks, Fall on us, and hide us from the face of him that sitteth on the throne, and from the wrath of the Lamb:
Rev 6:17 For the great day of his wrath is come; and who shall be able to stand?
.
I want to point out that the coming of the Lord in Matthew 24, Revelation 6, and Revelation 14, are very different from the coming in Revelation 19.
Revelation 6:12-13 echoes Matthew 24 almost perfectly, the same events preceeding represented by the horsemen, deception/false messiahs/white horse, wars and rumors of wars/red horse, famines/black horse, pestilences/pale horse, tribulations/fifth seal martyrs, cosmological signs/sixth seal signs. Revelation 6 is John's version of the Olivet discourse basically.
Compare how Jesus comes in Matthew 24, and Revelation 14, and Revelation 1 for that matter
Matthew 24:30
30 And then shall appear the sign of the Son of man in heaven: and then shall all the tribes of the earth mourn, and they shall see the Son of man coming in the clouds of heaven with power and great glory.
Revelation 14:14
14 And I looked, and behold a white cloud, and upon the cloud one sat like unto the Son of man, having on his head a golden crown, and in his hand a sharp sickle.
Revelation 1:7
7 Behold, he cometh with clouds; and every eye shall see him, and they also which pierced him: and all kindreds of the earth shall wail because of him. Even so, Amen.
Now you might think this is the same event as Revelation 19.. but in any of those does He come on a white horse as in Revelation 19? No.
In fact, in the Revelation 6 description, what is Jesus sitting on, I'll give you a hint, it's not a horse.
Revelation 6:15-16
15 And the kings of the earth, and the great men, and the rich men, and the chief captains, and the mighty men, and every bondman, and every free man, hid themselves in the dens and in the rocks of the mountains;
16 And said to the mountains and rocks, Fall on us, and hide us from the face of him that sitteth on the throne, and from the wrath of the Lamb:
so in this sixth seal coming that sounds like Matthew 24's coming when He comes in the clouds to gather His saints, He's not on a horse, He's on a throne. The Revelation 19 coming is very different, instead of coming in the clouds He comes all the way down to earth on a white horse.
It seems like 2 separate events. 1 brings the gathering of saints followed by the wrath of God, and 1 after the wrath of God, coming down WITH His saints to finish off the beast and false prophet and their armies.
We all know the Revelation 19 coming of our Lord his clothes are dipped in blood, and He's not here to resurrect or save anyone but as a conquering king that annihilates the wicked.
Isaiah 63:1-4
63 Who is this that cometh from Edom, with dyed garments from Bozrah? this that is glorious in his apparel, travelling in the greatness of his strength? I that speak in righteousness, mighty to save.
2 Wherefore art thou red in thine apparel, and thy garments like him that treadeth in the winefat?
3 I have trodden the winepress alone; and of the people there was none with me: for I will tread them in mine anger, and trample them in my fury; and their blood shall be sprinkled upon my garments, and I will stain all my raiment.
4 For the day of vengeance is in mine heart, and the year of my redeemed is come.
I take note of that year measurement of time when most people say the Day of the Lord is a single 24 hour day.
Revelation 9:5
5 And to them it was given that they should not kill them, but that they should be tormented five months: and their torment was as the torment of a scorpion, when he striketh a man.
I think that precludes the wrath of God being 1 24 hour day, but a year? That sounds likely, 1 single part of the wrath of God lasts 5 months.
anyway, kind of an aside since this is not specifically Daniel, though all that prophetic books and Olivet discourse I think are relevant to Daniel.
