Ezekiel 30:13

Thus saith the Lord GOD; I will also destroy the idols, and I will cause their images to cease out of Noph; and there shall be no more a prince of the land of Egypt: and I will put a fear in the land of Egypt.

I will destroy the idols ... of Noph - Memphis, the capital of Middle Egypt, and the stronghold of "idols." Though no record exists of Nebuchadnezzar's 'destroying' these, we know from Herodotus, etc., that Cambyses took Pelusium, the key of Egypt, by placing before his army dogs, cats, etc., all held sacred in Egypt, so that no Egyptian would use any weapon against them. He slew Apis, the sacred ox, and burned other idols of Egypt.

There shall be no more a prince of the land of Egypt - referring to the anarchy that prevailed in the civil wars between Apries and Amasis at the time of Nebuchadnezzar's invasion. There shall no more be a prince of the land of Egypt, ruling the whole country; or, no independent prince.
