《左传·昭公·昭公十四年》
司徒老祁、虑癸假装发病，派人请求南蒯说： 下臣愿意接受盟约，然而疾病发作。如果托您的福而不死，请等病稍稍好一点再和您结盟。 
司徒老祁、虑癸伪废疾，使请于南蒯曰： 臣愿受盟而疾兴，若以君灵不死，请待间而盟。 
Grand Administrator Lao Qi and Lu Gui pretended to fall ill and sent someone to ask Nan Kuai, saying: "Your minister is willing to accept the covenant, but the disease has struck. If I am fortunate enough not to die, please wait until I am slightly better before making a covenant with you. "
