DUKE. I do fear, too dreadful. Sith ’twas my fault to give the people scope, ’Twould be my tyranny to strike and gall them For what I bid them do; for we bid this be done When evil deeds have their permissive pass And not the punishment. Therefore, indeed, my father, I have on Angelo imposed the office; Who may in th’ ambush of my name strike home, And yet my nature never in the fight To do in slander. And to behold his sway, I will, as ’twere a brother of your order, Visit both prince and people. Therefore, I prithee, Supply me with the habit, and instruct me How I may formally in person bear Like a true friar. Moe reasons for this action At our more leisure shall I render you; Only, this one: Lord Angelo is precise; Stands at a guard with envy; scarce confesses That his blood flows or that his appetite Is more to bread than stone. Hence shall we see, If power change purpose, what our seemers be.
