《资治通鉴·唐纪·唐纪十三》
长孙无忌说： 盖苏文自己也知道罪行严重，害怕大国的讨伐，必然要严加防备，陛下稍稍容忍一些，他得以自我保全，必然会更加骄横，更加无恶不作，此后再去讨伐，也不算晚啊。 
长孙无忌曰： 盖苏文自知罪大，畏大国之讨，必严设守备，陛下姑为之隐忍，彼得以自安，必更骄惰，愈肆其恶，然后讨之，未晚也。 
Changsun Wuyi said: Ge Suwen himself also knows that his crimes are serious. He is afraid of being punished by the powerful countries, and he must be strictly guarded against. If Your Majesty tolerates him a little, he will be able to protect himself and will surely become even more arrogant and do more evil. It will not be too late to punish him after that.
