《国语·周语·太子晋谏灵王壅谷水》
现在我们的施政恐怕有违背天理之处，从而扰动了谷、洛二水的神灵，使它们争流相斗，以致为害王宫，陛下要堵塞掩饰，恐怕是不行的。
今吾执政无乃实有所避，而滑夫二川之神，使至于争明，以妨王宫，王而饰之，无乃不可乎！
I am afraid that there is something that violates the law of heaven in our current administration, which disturbs the gods of the two rivers in Gu and Luo, causing them to fight against each other, so as to harm the palace. It is probably impossible for His Majesty to block up and conceal it.
