《战国策·楚一·苏秦为赵合从说楚威王》
身为人臣却要主张割让主人的土地，来结交虎狼一样的秦国并使它强大起来，来侵略天下各国，最终遭受到秦国带来的祸患，但根本不顾自身将要遭受的灾祸。
夫为人臣而割其主之地，以外交强虎狼之秦，以侵天下，卒有秦患，不顾其祸。
As ministers, they advocated giving up their master's lands to make friends with the Qin, a country as ferocious as a tiger or wolf, and make it stronger so that it could invade other countries, and yet they did not bear in mind their own future disasters.
