《左传·隐公·隐公十一年》
郑庄公让许国大夫百里事奉许叔住在许都的东部边邑，说： 上天降祸于许国，鬼神确实对许君不满意，而借我的手惩罚他。
郑伯使许大夫百里奉许叔以居许东偏，曰： 天祸许国，鬼神实不逞于许君，而假手于我寡人。
Duke Zhuang of Zheng ordered the大夫 Bai Li of the State of Xu to serve Uncle Xu in the eastern outskirts of Xu Du, saying: "Heaven has brought disaster upon the State of Xu, and the gods are indeed dissatisfied with the King of Xu. They borrowed my hand to punish him."
