Isaiah 20:2-4

NHEB(i) 2 at that time the LORD spoke by Isaiah the son of Amoz, saying, "Go, and loosen the sackcloth from off your waist, and take your sandals off your feet." He did so, walking naked and barefoot. 3 The LORD said, "As my servant Isaiah has walked naked and barefoot three years for a sign and a wonder concerning Egypt and concerning Ethiopia, 4 so the king of Assyria will lead away the captives of Egypt and the exiles of Ethiopia, young and old, naked and barefoot, and with buttocks uncovered, to the shame of Egypt.
