Isaiah 20:3-6

3Then the Lord said, “Just as my servant Isaiah has gone stripped and barefoot for three years, as a sign and portent against Egypt and Cush, 4so the king of Assyria will lead away stripped and barefoot the Egyptian captives and Cushite exiles, young and old, with buttocks bared—to Egypt’s shame. 5Those who trusted in Cush and boasted in Egypt will be dismayed and put to shame. 6In that day the people who live on this coast will say, ‘See what has happened to those we relied on, those we fled to for help and deliverance from the king of Assyria! How then can we escape?’ ”
