《孟子·梁惠王章句下·第七节》
左右亲信都说某人该杀，不可轻信；众位大夫都说某人该杀，还是不可轻信；全国的人都说某人该杀，然后去考查他，发现他真该杀，再杀掉他。
左右皆曰可杀，勿听；诸大夫皆曰可杀，勿听；国人皆曰可杀，然后察之；见可杀焉，然后杀之。
Trusted people on the left and right say that a certain person should be killed, but you should not believe them lightly; all the ministers say that a certain person should be killed, but you should still not believe them lightly; everyone in the country says that a certain person should be killed, and then you examine him and find that he really should be killed, and then kill him.
