Ezekiel 30:9

Messengers go forth from me in ships. — Comp. Isaiah 18:1. This does not mean the army of Nebuchadnezzar, which did not penetrate into Ethiopia, but the flying Egyptians, who ascend the Nile to seek safety in Ethiopia, and alarm it with the tidings of Egypt’s fall. The “careless” are the secure Ethiopians. “As in the day of Egypt” is a reference to a past event, and can only mean, as in the day of judgment upon Egypt at the Exodus.
