Isaiah 20:2-5

MKJV(i) 2 at that time Jehovah spoke by Isaiah the son of Amoz, saying, Go and take the sackcloth off your loins, and take your shoe off your foot. And he did so, walking naked and barefoot. 3 And Jehovah said, Just as My servant Isaiah has walked naked and barefoot three years, a sign and wonder on Egypt and on Ethiopia; 4 so shall the king of Assyria lead away Egypt's prisoners, and the Ethiopian exiles, young and old, naked and barefoot, even with uncovered buttocks, to the shame of Egypt. 5 And they shall be afraid and ashamed of Ethiopia their hope, and of Egypt their glory.
