So shall the king of Assyria - The emphasis here is on the word "so." As Isaiah has walked naked, that is, stripped off his usual clothing, "so" shall the Egyptians and Ethiopians be led away "stripped" of all their possessions.

The Egyptians prisoners, and the Ethiopians captives - The Egyptians and Ethiopians, or Cushites, were often united in an alliance, and appear to have been when this prophecy was delivered. Thus Nahum 3:8 :

Ethiopia and Egypt were her strength, and it was infinite;

Put and Lubim were thy helpers.

To the shame of Egypt - It shall be a disgrace to them to be subdued, and to be carried captive in so humiliating a manner. It is remarked by Belzoni ('Operations and Recent Discoveries in Egypt and Nubia'), that in the figures on the remains of their temples, prisoners are often represented as naked, or only in aprons, with disheveled hair, and with their hands chained. He also remarks, that on a "bas-relief," on the recently-discovered graves of the kings of Thebes, a multitude of "Egyptian and Ethiopian prisoners" are represented - showing that Egypt and Ethiopia were sometimes "allied," alike in mutual defense and in bondage (compare Isaiah 47:2, and Nahum 3:5).

So shall the king of Assyria lead away the Egyptians prisoners, and the Ethiopians captives,.... As beasts are led or driven, being taken prisoners, and carried captive by the king of Assyria, namely Sargon, whoever is intended by him:

young and old; without any regard to age, sparing none for their tender years or gray hairs:

naked and barefoot; as prisoners of war commonly are, being stripped by their conquerors of their clothes, and having only a few rags given them to cover their nakedness with, and obliged to travel without shoes on their feet:

even with their buttocks uncovered, to the shame of Egypt; having no clothes on them to cover those parts; or the skirts of their garments cut off, as David's servants were by the Ammonites, 2 Samuel 10:4 and this to humble and mortify the pride of the Egyptians.

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.

20:4 Uncovered - Having their garments cut off by the middle.

the Egyptians...: Heb. the captivity of Egypt

shame: Heb. nakedness

4. buttocks uncovered-Belzoni says that captives are found represented thus on Egyptian monuments (Isa 47:2, 3; Na 3:5, 8, 9), where as here, Egypt and Ethiopia are mentioned as in alliance.

20:1-6 The invasion and conquest of Egypt and Ethiopia. - Isaiah was a sign to the people by his unusual dress, when he walked abroad. He commonly wore sackcloth as a prophet, to show himself mortified to the world. He was to loose this from his loins; to wear no upper garments, and to go barefooted. This sign was to signify, that the Egyptians and Ethiopians should be led away captives by the king of Assyria, thus stripped. The world will often deem believers foolish, when singular in obedience to God. But the Lord will support his servants under the most trying effects of their obedience; and what they are called upon to suffer for his sake, commonly is light, compared with what numbers groan under from year to year from sin. Those who make any creature their expectation and glory, and so put it in the place of God, will, sooner or later, be ashamed of it. But disappointment in creature-confidences, instead of driving us to despair, should drive us to God, and our expectation shall not be in vain. The same lesson is in force now; and where shall we look for aid in the hour of necessity, but to the Lord our Righteousness, throne of grace, and serving with each other in the same business of religion, should end all disputes, and unite the hearts of believers to each other in holy love.
