《论衡·卷十九·恢国篇》
周武王作为殷代西方诸侯的领袖，以臣子身份侍奉纣王。作为一个臣子而去讨伐君王，伯夷、叔齐认为这是可耻的，牵住周武王的马进行规劝，周武王不听他们的劝告，他们不吃周朝的粮食，饿死在首阳山。
武王为殷西伯，臣事於纣，以臣伐，夷、齐耻之，扣马而谏，武王不听，不食周粟，饿死首阳。
As the leader of the vassal states in the west of the Shang Dynasty, King Wu of Zhou served King Zhou as a subject. Boi and Shu Qi thought it was a shame to attack the king as a subject, so they held King Wu's horse to persuade him, but he ignored them. They refused to eat the food of the Zhou Dynasty and starved to death in Shouyang Mountain.
