Ezekiel 30:8

6 For this is what the LORD says: The allies of Egypt will fall, and her proud strength will collapse. From Migdol to Syene they will fall by the sword within her, declares the Lord GOD.

7 They will be desolate among desolate lands, and their cities will lie among ruined cities.

Then they will know that I am the LORD when I set fire to Egypt and all her helpers are shattered.

9 On that day messengers will go out from Me in ships to frighten Cush out of complacency. Anguish will come upon them on the day of Egypt’s doom. For it is indeed coming.

10 This is what the Lord GOD says: I will put an end to the hordes of Egypt by the hand of Nebuchadnezzar king of Babylon.

This was said to Israel at a particular time, so it is wise to read it together with the surrounding text. Do read the surrounding verses too, because the context often says more than a single verse.
