'Naked and Barefoot' in the Bible

Then spake the LORD unto Isaiah the son of Amoz, saying, "Go, and loose off that sackcloth from thy loins, and put off thy shoes from thy feet." And so he did, going naked and barefoot.

Then said the LORD, "Whereas my servant Isaiah goeth naked and barefoot, it is a token and signifying of the thing that after three years shall come upon Egypt and Ethiopia.

For even thus shall the king of the Assyrians drive both young and old, as prisoners, naked and barefoot, out of Egypt and Ethiopia. And shall discover the shame of Egypt.
