《资治通鉴·汉纪·汉纪三十二》
刘秀估计冯、黄防两人不可能长久和睦，势必互相冲突，因此回答邓禹说： 逮捕冯的人，一定是黄防。 
帝度愔、防不能久和，势必相忤，因报禹曰： 缚冯愔者，必黄防也。 
Liu Xiu figured that it would be impossible for Feng and Huang Fang to coexist peacefully for long. They would inevitably clash. So he said to Deng Yu: “The person who will capture Feng will be none other than Huang Fang.”
