A Sign against Egypt and Cush
The oracle is set in the year Assyria's commander attacked and captured Ashdod, grounding the sign in real geopolitical pressure. Yet before that public event the LORD had already ordered Isaiah to remove his sackcloth and sandals, making the prophet himself the instrument by which God's warning would be seen rather than merely heard.
B1efore 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.”
After three years of Isaiah walking stripped and barefoot as a sign and omen, the LORD explains its meaning: the king of Assyria will lead away the captives of Egypt and exiles of Cush in exposed humiliation. The enacted prophecy therefore strips false prestige from these nations in advance, showing that their apparent strength will end in shameful defeat.
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.
Those who treated Cush as hope and Egypt as boast will be dismayed once the sign's fulfillment becomes visible. The coastland dwellers who once fled toward those powers for rescue against Assyria are left asking how they can possibly escape now, because the collapse of their chosen refuge exposes the bankruptcy of their political trust.
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?’”
