Cas. 'For ever and for ever, farewell, Brutus!
If we do meet again, we'll smile indeed;
If not, 'tis true this parting was well made.'
Bru. 'Why then, lead on. O, that a man might know
The end of this day's business ere it come!
But it sufficeth that the day will end,
And then the end is known. Come, ho! away!'
from Julius Caesar (Act V, Scene II)
by William Shakespeare
