M. Tullius Cicero, Against Verres
C. D. Yonge, Ed.

And I have a greater burden on me than those who have accused other men, (if that deserve to be called a burden which you bear with pleasure and delight,)—but still I have in one respect undertaken a greater burden than others who have done the same thing, because all men are required to abstain most especially from those vices for which they have reproved another. Have you accused any thief or rapacious man? You must for ever avoid all suspicion of avarice. Have you prosecuted any spiteful or cruel man? You must for ever take care not to appear in any matter the least harsh or severe. A seducer? an adulterer? You must, take care most diligently that no trace of licentiousness be ever seen in your conduct. In short, everything which you have impeached in another must be earnestly avoided by you your self. In truth, not only no accuser, but no reprover even can be endured, who is himself detected in the vice which he reproves in another.
