《战国策·赵三·魏使人因平原君请从于》
如今魏国请求合纵，然而大王不听，其实这是魏国自求祸害，可是大王却是拒绝利益。
今魏求从，而王不听，是魏求害，而王辞利也。
"Now that the State of Wei proposes to join the others in a vertical alliance, if Your Majesty refuses, it will mean that Wei will bring disaster upon itself, yet Your Majesty will have rejected an opportunity for profit."
