The fact of the destruction of Egypt by Babylon was well known after the detailed and strictly recorded prophecies of Ezekiel.
Ezek 29:1 In the tenth year, in the tenth month, in the twelfth day of the month, the word of the LORD came unto me, saying, 2 Son of man, set thy face against Pharaoh king of Egypt, and prophesy against him, and against all Egypt:
Ezek 29:17 And it came to pass in the seven and twentieth year, in the first month, in the first day of the month, the word of the LORD came unto me, saying, 18 Son of man, Nebuchadrezzar king of Babylon caused his army to serve a great service against Tyrus:
Ezek 30:1 The word of the LORD came again unto me, saying, 2 Son of man, prophesy and say, Thus saith the Lord GOD; Howl ye, Woe worth the day! 3 For the day is near, even the day of the LORD is near, a cloudy day; it shall be the time of the heathen. 4 And the sword shall come upon Egypt, and great pain shall be in Ethiopia, when the slain shall fall in Egypt, and they shall take away her multitude, and her foundations shall be broken down.
Ezek 30:10 Thus saith the Lord GOD; I will also make the multitude of Egypt to cease by the hand of Nebuchadrezzar king of Babylon. 11 He and his people with him, the terrible of the nations, shall be brought to destroy the land: and they shall draw their swords against Egypt, and fill the land with the slain.
Ezek 30:20 And it came to pass in the eleventh year, in the first month, in the seventh day of the month, that the word of the LORD came unto me, saying, 21 Son of man, I have broken the arm of Pharaoh king of Egypt; and, lo, it shall not be bound up to be healed, to put a roller to bind it, to make it strong to hold the sword.
Ezek 31:1 And it came to pass in the eleventh year, in the third month, in the first day of the month, that the word of the LORD came unto me, saying, 2 Son of man, speak unto Pharaoh king of Egypt, and to his multitude;
Ezek 32:1 And it came to pass in the twelfth year, in the twelfth month, in the first day of the month, that the word of the LORD came unto me, saying, 2 Son of man, take up a lamentation for Pharaoh king of Egypt, and say unto him, Thou art like a young lion of the nations, and thou art as a whale in the seas: and thou camest forth with thy rivers, and troubledst the waters with thy feet, and fouledst their rivers.
...11 For thus saith the Lord GOD; The sword of the king of Babylon shall come upon thee. 12 By the swords of the mighty will I cause thy multitude to fall, the terrible of the nations, all of them: and they shall spoil the pomp of Egypt, and all the multitude thereof shall be destroyed.
Ezek 32:17 It came to pass also in the twelfth year, in the fifteenth day of the month, that the word of the LORD came unto me, saying, 18 Son of man, wail for the multitude of Egypt, and cast them down, even her, and the daughters of the famous nations, unto the nether parts of the earth, with them that go down into the pit.
There are many particulars about this compilation of prophesy which speak of the utter destruction of the land of Egypt by the Babylonians. The land would be found utterly desolate and greatly effected for forty years. It will never more rule over the nations, losing it's preeminent place
29:8 Therefore thus saith the Lord GOD; Behold, I will bring a sword upon thee, and cut off man and beast out of thee. 9 And the land of Egypt shall be desolate and waste; and they shall know that I am the LORD: because he hath said, The river is mine, and I have made it. 10 Behold, therefore I am against thee, and against thy rivers, and I will make the land of Egypt utterly waste and desolate, from the tower of Syene even unto the border of Ethiopia. 11 No foot of man shall pass through it, nor foot of beast shall pass through it, neither shall it be inhabited forty years.
13 Yet thus saith the Lord GOD; At the end of forty years will I gather the Egyptians from the people whither they were scattered: 14 And I will bring again the captivity of Egypt, and will cause them to return into the land of Pathros, into the land of their habitation; and they shall be there a base kingdom. 15 It shall be the basest of the kingdoms; neither shall it exalt itself any more above the nations: for I will diminish them, that they shall no more rule over the nations.
Nebuchadnezzer is commended for his destruction of Tyre in accordance with the direction of God: (Nebuchadrezzar king of Babylon caused his army to serve a great service against Tyrus: every head was made bald, and every shoulder was peeled: yet had he no wages, nor his army, for Tyrus, for the service that he had served against it: 19 Therefore thus saith the Lord GOD; Behold, I will give the land of Egypt unto Nebuchadrezzar king of Babylon; and he shall take her multitude, and take her spoil, and take her prey; and it shall be the wages for his army. 20 I have given him the land of Egypt for his labour wherewith he served against it, because they wrought for me, saith the Lord GOD.) He proceeds to detail destruction in all of the major cities of Egypt, Including the city of No (Thebes) the greatest in Egypt.
Jeremiah took up a similar prophecy after Jerusalem was destroyed by the Babylonians.
Jer 43:8 Then came the word of the LORD unto Jeremiah in Tahpanhes, saying, 9 Take great stones in thine hand, and hide them in the clay in the brickkiln, which is at the entry of Pharaoh's house in Tahpanhes, in the sight of the men of Judah; 10 And say unto them, Thus saith the LORD of hosts, the God of Israel; Behold, I will send and take Nebuchadrezzar the king of Babylon, my servant, and will set his throne upon these stones that I have hid; and he shall spread his royal pavilion over them. 11 And when he cometh, he shall smite the land of Egypt, and deliver such as are for death to death; and such as are for captivity to captivity; and such as are for the sword to the sword. 12 And I will kindle a fire in the houses of the gods of Egypt; and he shall burn them, and carry them away captives: and he shall array himself with the land of Egypt, as a shepherd putteth on his garment; and he shall go forth from thence in peace. 13 He shall break also the images of Bethshemesh, that is in the land of Egypt; and the houses of the gods of the Egyptians shall he burn with fire.
Jeremiah even names the Pharaoh which shall experience this destruction:
Jer 43:30 Thus saith the LORD; Behold, I will give Pharaohhophra king of Egypt into the hand of his enemies, and into the hand of them that seek his life; as I gave Zedekiah king of Judah into the hand of Nebuchadrezzar king of Babylon, his enemy, and that sought his life.
Pharaoh Hophra was to follow Pharaoh Necho as the focus of Gods wrath, an important fact as Necho lost to Babylon at the battle of Carchemish.
Jer 46:13 The word that the LORD spake to Jeremiah the prophet, how Nebuchadrezzar king of Babylon should come and smite the land of Egypt.
Jer 46:25 The LORD of hosts, the God of Israel, saith;
Behold, I will punish the multitude of No,
and Pharaoh, and Egypt, with their gods, and their kings;
even Pharaoh, and all them that trust in him:
26 And I will deliver them into the hand of those that seek their lives,
and into the hand of Nebuchadrezzar king of Babylon,
and into the hand of his servants:
and afterward it shall be inhabited,
as in the days of old, saith the LORD.
It is important that we understand that these two great prophets could not have been wrong or they would not be revered today as the prophets they are. They prophesied from two different viewpoints but to the same exacting story, Nebuchadnezzer of Babylon would destroy Egypt, ruled the by Pharaoh Hophra and the land would be desolate for 40 years and then the captivity would return to re-inhabit an Egypt which never again would be as powerful as it had been.
Why bring this up? Because according to current history as taught everywhere, this never happened, It cannot be; according to currently accepted Egyptian chronology. Why? because the current Egyptian chronology is wrong. if you want to know more about this subject you can read the first book in the displaced dynasties series, found here: http://www.displaceddynasties.com/
