Isaiah 20
2 Ref At that time the word of the Lord came to Isaiah, the son of Amoz, saying, Go, and take off your robe, and your shoes from your feet; and he did so, walking unclothed and without shoes on his feet.
3 Ref And the Lord said, As my servant Isaiah has gone unclothed and without shoes for three years as a sign and a wonder to Egypt and Ethiopia,
4 Ref So will the king of Assyria take away the prisoners of Egypt and those forced out of Ethiopia, young and old, unclothed and without shoes, and with backs uncovered, to the shame of Egypt.
