Isaiah 20:2-4

New Catholic Bible

² At that time the Lord spoke to Isaiah, the son of Amoz, and issued this warning, “Go forth, take off the sackcloth from your waist, and remove the sandals from your feet.” Isaiah did as he had been instructed, walking naked and barefoot.

³ Then the Lord said, “Just as my servant Isaiah has gone naked and barefoot for three years as a sign and portent against Egypt and Ethiopia, ⁴ so shall the king of Assyria lead away the captives of Egypt and the exiles from Ethiopia, both the young and the aged, naked and barefoot, with their buttocks exposed, to the shame of Egypt.
