Isaiah 20:4
So shall the king of Assyria lead away the Egyptians prisoners, and the Ethiopians captives, young and old, naked and barefoot, even with their buttocks uncovered, to the shame of Egypt. So shall the king of Assyria lead away the Egyptians prisoners, and the Ethiopians captives, young and old, naked and barefoot, even with their buttocks uncovered, to the shame of Egypt.
The king of Assyria would lead away the Egyptians as prisoners and the Ethiopians as captives, young and old, naked and barefoot, exposed, to the shame and public humiliation and disgrace of Egypt.
Naked here means stripped of the customary outer robe or outer garments rather than completely unclothed.
The same sense is used when people are described as naked while working or running and in the accounts of Peter and Saul.
The predicted captivity refers to Sargon's conquest of Egypt and Ethiopia, when the Assyrian king would carry their people away as captives.
Esar Haddon and Ashur-bani-pal helped bring about a partial fulfillment of the prophecy concerning Egypt.
