Famous quotes containing the word double:
“Go; and if that word have not quite killed thee,
Ease me with death by bidding me got too.
Oh, if it have, let my word work on me,
And a just office on a murderer do.
Except it be too late to kill me so,
Being double dead: going, and bidding go.”
—John Donne (1572–1631)
