《资治通鉴·唐纪·唐纪五》
赦令颁布后，王世充、窦建德的余党仍然有人被迁移到很远的地方，治书侍御史孙伏伽上言： 可以没有军队、粮食，但不可以不讲信义。陛下既然已经发布赦令，又将人迁走，这是自己违背了自己的本心，让大臣平民以哪个为标准呢？
赦令既下，而王、窦馀党尚有远徙者，治书侍御史孙伏伽上言： 兵、食可去，信不可去，陛下已赦而复徙之，是自违本心，使臣民何所凭依？
After the amnesty decree was issued, some of the remnants of Wang Shichong and Dou Jiande were still moved to a great distance. Zhi Shu Shiyu Shi Sun Fugai advised: "You can have no army or food, but you can't break your word. Since your Majesty has issued an amnesty decree, and then moved people away, this is against your own heart. What standard do you want the ministers and civilians to follow?"
