“Thus says the Lord Yahweh, I will also make the multitude (of either people or wealth) of Egypt to cease by the hand of Nebuchadrezzar, king of Babylon. He and his people with him, the terrible 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.”
Through Nebuchadnezzar God will ‘make the multitude of Egypt to cease'. This may refer to population or to wealth, but in this section of Ezekiel ‘multitude' tends to mean people. So either the population would be decimated or their wealth would be. In fact in such a war it would happen to both as cattle were slaughtered or run off, spoils were seized and people were put to the sword. For ‘the terrible of the nations' compare Ezekiel 28:7. Note that Nebuchadnezzar and his hordes ‘will be brought in', that is by Yahweh. They are seen as under Yahweh's command.
