Isaiah 20:2-4

Revised Standard Version Catholic Edition

² at that time the Lord had spoken by Isaiah the son of Amoz, saying, “Go, and loose the sackcloth from your loins and take off your shoes from your feet,” and he had done so, walking naked and barefoot— ³ the Lord said, “As my servant Isaiah has walked naked and barefoot for three years as a sign and a portent against Egypt and Ethiopia, ⁴ so shall the king of Assyria lead away the Egyptians captives and the Ethiopians exiles, both the young and the old, naked and barefoot, with buttocks uncovered, to the shame of Egypt.
