《左传·昭公·昭公五年》
君王将要把亲善换成怨恨，确实违背礼仪以招致敌人，而又没有应有的防备，让下臣们去当俘虏以满足君王的心意，有什么不可以呢？ 
君将以亲易怨，实无礼以速寇，而未有其备，使群臣往遗之禽，以逞君心，何不可之有？ 
The king is going to turn kindness into resentment, it is indeed against the etiquette to attract enemies, but without proper precautions, what is wrong with letting the ministers to be prisoners to satisfy the king's mind?
