You have the window, why not jump out there?
Mephistopheles.
It is a law which binds all ghosts and sprites;
Wherever they creep in, there too they must creep out;
I came in at the door, by the door I must go out.
Faust.
So so! then hell too has its laws and rights,
Thus might one profit by the powers of evil,
And make an honest bargain with the devil.
Mephistopheles.
