《史记·三十世家·齐太公世家》
管仲说： 如果被劫持时答应了人家的要求，然后又背弃诺言杀死人家，是满足于一件小小的快意之事，而在诸侯中却失去了信义，也就失去了天下人的支持，不能这样做。 
管仲曰： 夫劫许之而倍信杀之，愈一小快耳，而弃信于诸侯，失天下之援，不可。 
Guan Zhong argued against that, saying, "If you promised someone something and then killed him after getting what you wanted, you would satisfy a small grudge but lose all your integrity among lords and therefore the support of everyone under Heaven. We can't do that."
