John Gill Commentary Ezekiel 30:11

"He and his people with him, the terrible of the nations, shall be brought in to destroy the land; and they shall draw their swords against Egypt, and fill the land with the slain." — Ezekiel 30:11 (ASV)

He and his people with him He and his army, consisting chiefly of Chaldeans; though there were of other nations among them, as were in his army when he besieged Jerusalem, as seems to be suggested in the next clause:

the terrible of the nations shall be brought to destroy the land ; the Chaldeans, the most fierce, cruel, and terrible of all people, and others the most terrible that could be collected out of all nations under the yoke of the king of Babylon; and all of them terrible to the nations against whom they came, as now against Egypt to destroy it; see (Habakkuk 1:6Habakkuk 1:7) :

and they shall draw their swords against Egypt, and fill the land with the slain ; go through the land with their drawn swords, and kill all they meet; and not put them up till they have quite depopulated the land, and filled it with dead carcasses.
