DUKE. For this new-married man approaching here, Whose salt imagination yet hath wronged Your well-defended honour, you must pardon For Mariana’s sake. But as he adjudged your brother, Being criminal in double violation Of sacred chastity and of promise-breach Thereon dependent, for your brother’s life, 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. Then, Angelo, thy fault’s thus manifested, Which, though thou wouldst deny, denies thee vantage. We do condemn thee to the very block Where Claudio stooped to death, and with like haste. Away with him.
