Isaiah 20:2-4

2the Lord told Isaiah son of Amoz, “Take off the burlap you have been wearing, and remove your sandals.” Isaiah did as he was told and walked around naked and barefoot.

3Then the Lord said, “My servant Isaiah has been walking around naked and barefoot for the last three years. This is a sign—a symbol of the terrible troubles I will bring upon Egypt and Ethiopia.

4For the king of Assyria will take away the Egyptians and Ethiopians as prisoners. He will make them walk naked and barefoot, both young and old, their buttocks bared, to the shame of Egypt.
