Ezekiel 30:2-6
Son of man, prophesy and say, `Thus says the Lord God, Wail, Alas for the day! For 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. And a sword will come upon Egypt , and anguish will be in Ethiopia (Cush) when the slain fall in Egypt, they take away her wealth, and her foundations are torn down. Ethiopia, Put , Lud , all Arabia , Libya (Cub), and the people of the land that is in league will fall with them by the sword.'
.
Thus says the Lord, "Indeed, those who support Egypt will fall, and the pride of her power will come down; from Migdol to Syene they will fall within her by the sword," declares the Lord God.

The time frame of the prophecy in Ezekiel 30:1-9, is identified as the end-times period by the phrase, 'the Day of the Lord is near.' We know from our extensive study of scriptures that the Day of the Lord is the last part of the end-times 7 year period, after the Great Tribulation period. Since God has given us this clear signal by mentioning that the Day of the Lord is near, we know then that the war is in the Great Tribulation period and is World War 3. By the way, verses 10 and onward then jump to another period of time near when the prophecy was given through Ezekiel, concerning the time when Nebuchadnezzar was king of ancient Babylon..

Egypt is mentioned as the leader, and a number of allies of Egypt are cited. I've reinserted the original words back into the above text so that you can see them rather than the translator's guesses. Cush is mentioned, which we've discussed already as the black African Muslim nations which could include part of Sudan, Ethiopia, and Somalia. Remember in the Ezekiel 38 text where the translators substituted Libya for Put, well these same translators used Cub for Libya here in chapter 30. This time both Put and Cub are mentioned. Cub is the correct term for Libya, but that means Put identifies other North African Arab nations. That's why I said earlier that Put likely meant Libya, Tunisia, Algeria, and lower Sudan.
.
Arabia is mentioned among the allies of Egypt, which brings to mind Saudi Arabia. Others in the Arabian Peninsula include Kuwait, the United Arab Emirates, Oman, and Yemen. Saudi Arabia is pro-western now, but we all know that they have clandestinely supported the Palestinians and other groups with massive amounts of financial support, in all practicality playing both sides. In an all-out attack on Israel, the Saudis may throw their financial support against Israel and the West. Remember, they are keepers of the Muslim holy sites at Mecca and Medina, so they have many constituencies to satisfy. The Bible says that all Arabia will be in league with Egypt, so we know that the Saudis will choose the Arab/Muslim cause. Lud is mentioned and like so many others, I have no idea what modern nation Lud might be. Oh by the way, the term 'Migdol to Syene' means the area from what is now the Aswan Dam to the Nile delta. Migdol to Syene includes most of the population of modern Egypt.

Egypt is called the king of the South in Daniel 11:40-43, and they are the catalyst for the attack against Israel which causes World War 3.
.
Daniel 11:40-42
At the end time the king of the South will collide with him (antichrist), and the king of the North will storm against him with chariots, with horsemen, and with many ships; and he will enter countries, overflow them, and pass through. He will also enter the Beautiful Land (Israel), and many countries will fall; but these will be rescued out of his hand: Edom, Moab, and the foremost sons of Ammon. Then he will stretch out his hand against other countries, and the land of Egypt will not escape.
