《战国策·赵二·苏秦从燕之赵始合从》
苏秦从燕国到赵国开始倡导联合崤山以东六国对抗秦国的合纵策略。他游说赵王说： 普天之下，各诸侯国的卿相大臣，乃至普通老百姓，没有一个不尊崇大王施行仁义的行为的，很长时间以来，他们都愿接受您的教诲，向大王进献忠心。
苏秦从燕之赵，始合从，说赵王曰： 天下之卿相人臣，乃至布衣之士，莫不高贤大王之行义，皆愿奉教陈忠于前之日久矣。
Su Qin travelled from the State of Yan to the State of Zhao and there he first promoted the strategy of merging for a single attack of the six states to the east of the Xiao Pass to resist the State of Qin. Having talked his way round to the King of Zhao, he said: “Throughout the whole country, none of the ministers and officials of the feudal lords, right down to the ordinary people, do not hold Your Majesty in high esteem for your kindness and adherence to the principles of morality. For a long time now they have all been willing to accept your guidance and offer their loyalty to Your Majesty.”
