《宋史·列传·卷一百一十九》
张俊不行动，山阴于是陷落。金兵留在淮河边，范宗尹认为敌人未必能再渡河，赵鼎说： 不要寄希望于敌人不来，要依靠自己有准备以待之。 
俊不行，山阳遂陷，金人留淮上，范宗尹奏敌未必能再渡，鼎曰： 勿恃其不来，恃吾有以待之。
Zhang Jun did not act, and Shanyin fell. The Jin soldiers stayed on the bank of the Huai River. Fan Zongyin believed that the enemy might not be able to cross the river again. Zhao Ding said: Don't expect the enemy to not come, but rely on yourself to be prepared for it.
