Isaiah 20:3-4

And the Lord said, Like as my seruant Isaiah hath walked naked, and barefoote three yeeres, as a signe and wonder vpon Egypt, and Ethiopia, So shall the King of Asshur take away the captiuitie of Egypt, and the captiuitie of Ethiopia, both yong men and olde men, naked and barefoote, with their buttockes vncouered, to the shame of Egypt.
