The line, "O Scotland, Scotland!" occurs in Shakespeare’s play, _Macbeth_. In the scene within which "O Scotland, Scotland!" is said, Macduff is talking to Malcolm about the state of things in Scotland and its king. When Macduff says this, it is because he feels worry and sorrow for the state of things and for about what is revealed to him about the kingdom.
