DUKE VINCENTIO: Peace be with you! He who the sword of heaven will bear Should be as holy as severe; Pattern in himself to know, Grace to stand, and virtue go; More nor less to others paying Than by self-offences weighing. Shame to him whose cruel striking Kills for faults of his own liking! Twice treble shame on Angelo, To weed my vice and let his grow! O, what may man within him hide, Though angel on the outward side! How may likeness made in crimes, Making practise on the times, To draw with idle spiders' strings Most ponderous and substantial things! Craft against vice I must apply: With Angelo to-night shall lie His old betrothed but despised; So disguise shall, by the disguised, Pay with falsehood false exacting, And perform an old contracting.
