Isaiah 20:1-6
20 In the year of the Tartan’s coming to Ashdod, sent by King Sargon of Assyria, and attacking Ashdod and taking it,
2 at that time Jehovah spoke by Isaiah the son of Amos, saying “Go and undo the sackcloth off your waist and take off your shoes from your feet”; and he did so, going naked and barefoot.
3 And Jehovah said “As my servant Isaiah has gone naked and barefoot three years as token and portent regarding Egypt and Nubia,
4 * so the king of Assyria will drive along the Egyptian prisoners and the Nubian deportees, naked and barefoot and bare-breeched;
5 and they will be dismayed and put to shame for Nubia their cynosure and for Egypt their vaunt,
6 * and the inhabitant of this coast will say “There in that condition is our cynosure to whom we took flight for help, to be delivered from the king of Assyria, and how are we to escape?”
