In the year that the commander in chief, sent by Sargon king of Assyria, came to Ashdod and fought against it and captured it, the Lord spoke by Isaiah the son of Amoz. He told him to loose the sackcloth from his waist and take off his sandals from his feet. Isaiah did so and walked naked and barefoot.
Then the Lord explained the meaning: just as his servant Isaiah had walked naked and barefoot for three years as a sign and portent against Egypt and Cush, so the king of Assyria would lead away the captives of Egypt and the exiles of Cush, both the young and the old, naked and barefoot, with buttocks uncovered, to the shame of Egypt.
Those who had put their hope in Cush and boasted in Egypt will be dismayed and ashamed. The inhabitants of this coastland will say on that day: look at what has happened to those in whom we hoped and to whom we fled for help to be delivered from the king of Assyria; how shall we escape?
