NAB

In the year the general sent by Sargon, king of Assyria, came to Ashdod, fought against it, and captured it―

at that time the LORD had spoken through Isaiah, the son of Amoz: Go and take off the sackcloth from your waist, and remove the sandals from your feet. This he did, walking naked and barefoot.

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,

so shall the king of Assyria lead away captives from Egypt, and exiles from Ethiopia, young and old, naked and barefoot, with buttocks uncovered, the shame of Egypt.

They shall be dismayed and ashamed because of Ethiopia, their hope, and because of Egypt, their boast.

The inhabitants of this coastland shall say on that day, “See what has happened to those we hoped in, to whom we fled for help and deliverance from the king of Assyria! What escape is there for us now?”
