Isaiah 20:3-4

3After three years, the Lord said, ‘My servant Isaiah has walked without clothes and without shoes for three years. That is a sign to warn Egypt and Cush about what will happen to them.

4The king of Assyria will take away people from Egypt as prisoners. He will do the same thing to the people of Cush. Young people and old people will go as prisoners to Assyria. They will not wear any clothes or shoes. People will see their bare bodies. The Egyptians will be very ashamed.
