Targum su Isaia 20:78

In the year that Tharthan marched to Ashdod, (when Sargon, the king of Assyria, sent him,) and he waged battle against Ashdod, and subdued it;

At that time the Lord decreed by Isaiah, the son of Amoz, saying, Go and remove the sackcloth which is on thy loins, and put off thy sandals from off thy feet: and he did so, walking naked and barefoot.

And the Lord said, Like as my servant Isaiah hath walked naked and barefoot three years for a sign and wonder upon Egypt and Cush:

So shall the king of Assyria lead the captives, and the captivity of Cush, the young and old, naked and barefoot, even with their shame uncovered, to the disgrace of Egypt.

And they shall be afraid and confounded because of Cush, the place of their confidence, and because of Egypt, their boasting.

At that time the inhabitant of this island shall say: Such is become the place of our trust, to which we were hoping to flee for help to be delivered from before the king of Assyria, if hitherto they could not deliver themselves, how shall we be delivered?
