Jesus Himself showed us how prophesy works. It cuts in and out often mid verse! He read from Isa about His first coming, and stopped mid verse because the rest was about His second coming millennia later! In the chapter you read, it seems to make sense that the section below is prophesy, rather than being about a military battle.
Not so much.
None of this is prophesy, it is all past tense, and in line with many many other examples of How God is depicted as coming down to earth and doing battle time and again.
Foundations of the world discovered in that battle? They saw the Almighty there flying on angel wings? Where were those waters? Did all the earth hear His voice yelling there? That battle was near the sea, and the channels appeared?
Common Hebraic Apocalyptic Language.
This is How the writers of scripture discuss the fall of nations & armies.
The best way to understand apocalyptic writing is to study the many comings of God during the Old Testament times and see how that language is used in past situations. Once we see the way the prophets spoke of God's comings down during the Old Testament times, we are better equipped to think about how God comes all throughout history. Study the following comings of God in history and think about the way in which the prophets use familiar doom language in each case:
God Comes in a Cloud Against Ancient Egypt - 700s BC
Behold, Yahweh rides on a swift cloud, and comes to Egypt: and the idols of Egypt shall tremble at his presence; and the heart of Egypt shall melt in the midst of it. I will stir up the Egyptians against the Egyptians (
Isaiah 19:1-2)
God Comes to End Saul's Kingdom - 1000 BC
Then the earth shook and quaked, the foundations of heaven were trembling and were shaken, because He was angry. Smoke went up out of His nostrils, fire from His mouth devoured; coals were kindled by it. He bowed the heavens also, and came down with thick darkness under His feet. And He rode on a cherub and flew; And He appeared on the wings of the wind. And He made darkness canopies around Him, a mass of waters, thick clouds of the sky. From the brightness before Him coals of fire were kindled. The LORD thundered from heaven, and the Most High uttered His voice. And He sent out arrows, and scattered them, Lightning, and routed them. Then the channels of the sea appeared, the foundations of the world were laid bare by the rebuke of the LORD, at the blast of the breath of His nostrils. (2 Sam 22:8-16)
God Comes to Judge Nineveh - 600s BC
The LORD takes vengeance on His adversaries, and He reserves wrath for His enemies...In whirlwind and storm is His way, and clouds are the dust beneath His feet. He rebukes the sea and makes it dry; He dries up all the rivers. Bashan and Carmel wither; The blossoms of Lebanon wither. Mountains quake because of Him and the hills dissolve; Indeed the earth is upheaved by His presence, the world and all the inhabitants in it. (
Nahum 1:2-5)
God Comes to Judge Egypt in the Time of Nebuchadnezzar - 600s BC
The day is near, even the day of the LORD is near; It will be a day of clouds, a time of doom for the nations. A sword will come upon Egypt, and anguish will be in Ethiopia; When the slain fall in Egypt...And they will know that I am the LORD, when I set a fire in Egypt...I will also make the hordes of Egypt cease by the hand of Nebuchadnezzar king of Babylon. He and his people with him, the most ruthless of the nations, will be brought in to destroy the land; and they will draw their swords against Egypt and fill the land with the slain. (
Ezekiel 30:3-4,8, 10-11)
God Comes to Judge Israel at the Time of the Exile - 500s BC
As I live, says the Lord Yahweh, surely with a mighty hand, and with an outstretched arm, and with wrath poured out, will I be king over you: and I will bring you out from the peoples, and will gather you out of the countries in which you are scattered, with a mighty hand, and with an outstretched arm, and with wrath poured out; and I will bring you into the wilderness of the peoples, and there will I enter into judgment with you face to face...Hear the word of Yahweh: Thus says the Lord Yahweh, Behold, I will kindle a fire in you, and it shall devour every green tree in you, and every dry tree: the flaming flame shall not be quenched, and all faces from the south to the north shall be burnt thereby. All flesh shall see that I, Yahweh, have kindled it...Thus says Yahweh: Behold, I am against you, and will draw forth my sword out of its sheath, and will cut off from you the righteous and the wicked. Seeing then that I will cut off from you the righteous and the wicked, therefore shall my sword go forth out of its sheath against all flesh from the south to the north: and all flesh shall know that I, Yahweh, have drawn forth my sword out of its sheath (Ez 20:33-35,47-48; 21:3-5)
God Comes To Judge Ancient Babylon Using the Medes - 500s BC
Wail, for the day of the LORD is near; it will come like destruction from the Almighty! Therefore all hands will be feeble, and every human heart will melt, and they will be dismayed. Pangs and agony will seize them; they will be in anguish like a woman in labor. They will look aghast at one another; their faces will be aflame. See, the day of the LORD comes, cruel, with wrath and fierce anger, to make the earth a desolation, and to destroy its sinners from it. 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. I will punish the world for its evil, and the wicked for their iniquity...Therefore I will make the heavens tremble, and the earth will be shaken out of its place, at the wrath of the LORD of hosts in the day of his fierce anger. Like a hunted gazelle, or like sheep with no one to gather them, all will turn to their own people, and all will flee to their own lands. Whoever is found will be thrust through, and whoever is caught will fall by the sword. Their infants will be dashed to pieces before their eyes; their houses will be plundered, and their wives ravished. See, I am stirring up the Medes against them, who have no regard for silver and do not delight in gold. Their bows will slaughter the young men; they will have no mercy on the fruit of the womb; their eyes will not pity children. And Babylon, the glory of kingdoms, the splendor and pride of the Chaldeans, will be like Sodom and Gomorrah when God overthrew them. (
Isaiah 13:6-11, 13,15-19)
God Comes During the Maccabean Period
For I have bent Judah for me, I have filled the bow with Ephraim; and I will stir up your sons, Zion, against your sons, Greece, and will make you as the sword of a mighty man. Yahweh shall be seen over them, and his arrow shall go forth as the lightning; and the Lord Yahweh will blow the trumpet, and will go with whirlwinds of the south. Yahweh of Hosts will defend them; and they shall devour, and shall tread down the sling-stones; and they shall drink, and make a noise as through wine; and they shall be filled like bowls, like the corners of the altar. Yahweh their God will save them in that day (
Zechariah 9:13-16)
God Comes to Judge Jerusalem at AD 70
I saw, and behold a white cloud; and upon the cloud one sitting like to the Son of man, having on his head a crown of gold, and in his hand a sharp sickle. And another angel came out from the temple crying with a loud voice to him that sat upon the cloud: Thrust in thy sickle, and reap, because the hour is come to reap: for the harvest of the earth is ripe. And he that sat on the cloud thrust his sickle into the earth, and the earth was reaped. And another angel came out of the temple which is in heaven, he also having a sharp sickle. And another angel came out from the altar, who had power over fire; and he cried with a loud voice to him that had the sharp sickle, saying: Thrust in thy sharp sickle, and gather the clusters of the vineyard of the earth; because the grapes thereof are ripe. And the angel thrust in his sharp sickle into the earth, and gathered the vineyard of the earth, and cast it into the great press of the wrath of God: And the press was trodden without the city (
Revelation 14:14-20)
As we see from this brief survey of the cloud comings of God in history, they all follow a similar pattern, nature, and experience: trumpets, clouds, darkening of the constellations, shaking of earth's foundations, great tribulation and distress, God's coming down with his armies. The apocalyptic language is graphic, filled with doom, and repeated at each of God's comings.
