The very mercy of the law cries out Most audible, even from his proper tongue, 'An Angelo for Claudio, death for death!' Haste still pays haste, and leisure answers leisure; Like doth quit like, and MEASURE still FOR MEASURE.
The very mercy of the law cries out Loud and clear, even from his own mouth, 'An Angelo for Claudio, death for death!' Haste answers haste, and rest answers rest; Like for like, and MEASURE for MEASURE.
Duke Vincentio · Act 5, Scene 1
The Duke pronounces sentence on Angelo, invoking the play's title with perfect symmetry. The line is the thematic crescendo because it announces the play's central principle—that justice must be proportional, that every action has an equal and opposite reaction. It is also the moment where the Duke's long manipulation is revealed as a philosophy of justice itself.
Dear Isabel, I have a motion much imports your good; Whereto if you'll a willing ear incline, What's mine is yours and what is yours is mine.
Dear Isabel, I have a proposal that concerns your well-being; If you'll listen with a willing heart, What's mine is yours and what's yours is mine.
Duke Vincentio · Act 5, Scene 1
The Duke proposes marriage to Isabella after the chaos of the trial, speaking in the language of mutual exchange and ownership. The line is studied because it leaves Isabella's answer ambiguous—the text does not tell us if she accepts or refuses. It raises the final question of the play: has Isabella been saved, married off, or made complicit in her own subjection.
I would thou hadst done so by Claudio. Go fetch him hither; let me look upon him.
I wish you had done the same for Claudio. Go bring him here; let me see him.
Duke Vincentio · Act 5, Scene 1
The Duke, learning that the Provost spared Barnardine's life, wishes he had done the same for Claudio. The line is poignant because it reveals that mercy, not measure, is the Duke's true intention all along. It also reminds us that Claudio dies because the Provost obeyed orders, but that his death is undone by theatrical substitution—the Duke's power to resurrect.
