1Before the year that the chief commander, sent by Sargon king of Assyria, came to Ashdod and attacked and captured it, 2the LORD had already spoken through Isaiah son of Amoz, saying, “Go, remove the sackcloth from your waist and the sandals from your feet.” And Isaiah did so, walking around naked and barefoot. 3Then the LORD said, “Just as My servant Isaiah has gone naked and barefoot for three years as a sign and omen against Egypt and Cush, 4so the king of Assyria will lead away the captives of Egypt and the exiles of Cush, young and old alike, naked and barefoot, with bared buttocks—to Egypt’s shame. 5Those who made Cush their hope and Egypt their boast will be dismayed and ashamed. 6And on that day the dwellers of this coastland will say, ‘See what has happened to our source of hope, those to whom we fled for help and deliverance from the king of Assyria! How then can we escape?’”
Matthew Henry's Commentary
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?
