CALL me not rebel, though { here at every word
{in what I sing
If I no longer hail thee { King and Lord
{ Lord and King
I have redeemed myself with all I had,
And now possess my fortunes poor but glad.
With all I had I have redeemed myself,
And escaped at once from slavery and pelf.
The unruly wishes must a ruler take,
Our high desires do our low fortunes make:
Those only who desire palatial things
Do bear the fetters and the frowns of Kings;
Set free thy slave; thou settest free thyself.

Robert Louis Stevenson
