I see the beginning of birth pains in the time the (Two Witnesses) are raised to heaven, as the 3rd woe comes upon the earth, the final hours of earth's existence, near the battle of Armageddon, as the Nations are gathered to (The Day Of The Lord)

Isaiah 13:4-13KJV
4 The noise of a multitude in the mountains, like as of a great people; a tumultuous noise of the kingdoms of nations gathered together: the Lord of hosts mustereth the host of the battle.
5 They come from a far country, from the end of heaven, even the Lord, and the weapons of his indignation, to destroy the whole land.
6 Howl ye; for the day of the Lord is at hand; it shall come as a destruction from the Almighty.
7 Therefore shall all hands be faint, and every man's heart shall melt:
8 And
they shall be afraid: pangs and sorrows shall take hold of them; they shall be in pain as a woman that travaileth: they shall be amazed one at another; their faces shall be as flames.
9 Behold, the day of the Lord cometh, cruel both with wrath and fierce anger, to lay the land desolate: and he shall destroy the sinners thereof out of it.
10 For the stars of heaven and the constellations thereof shall not give their light: the sun shall be darkened in his going forth, and the moon shall not cause her light to shine.
11 And I will punish the world for their evil, and the wicked for their iniquity; and I will cause the arrogancy of the proud to cease, and will lay low the haughtiness of the terrible.
12 I will make a man more precious than fine gold; even a man than the golden wedge of Ophir.
13 Therefore I will shake the heavens, and the earth shall remove out of her place, in the wrath of the Lord of hosts, and in the day of his fierce anger.
(Birth Pains)
Luke 21:25-26KJV
25 And there shall be signs in the sun, and in the moon, and in the stars; and upon the earth distress of nations, with perplexity; the sea and the waves roaring;
26 Men's hearts failing them for fear, and for looking after those things which are coming on the earth: for the powers of heaven shall be shaken.
(Birth Pains)
Revelation 6:15-17KJV
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:
17 For the great day of his wrath is come; and who shall be able to stand?
