《战国策·赵一·知伯从韩魏兵以攻赵》
虽然贤君跟韩、魏相约灭赵以后就和韩、魏三分赵国领土，可是现在晋阳只差三丈就被淹没，连石臼和炉灶都生了青蛙，饿到了人马相食的地步，晋阳被攻陷指日可待，然而韩、魏君主不但不喜，反倒忧愁，这不是表明他们将要背叛还是什么呀？ 
今约胜赵而三分其地。今城不没者三板，臼灶生蛙，人马相食，城降有日，而韩魏之君无熹志而有忧色，是非反如何也? 
Although our wise lord and Han and Wei agreed to divide Zhao's territory into three parts after Zhao is destroyed, now Jinyang is only ten feet from being flooded, and even frogs have grown in the mortars and stoves. The people and horses are so hungry that they are eating each other. Jinyang is about to fall, but the rulers of Han and Wei are not only not happy, but are instead worried. Doesn't this show that they are about to betray others?
