《后汉书·列传·邓寇列传》
光武说： 即便这样，想干什么呢？ 邓禹说： 但愿明公威德加于四海，我得为明公效尺寸之力，垂功名于史册哩。

Guangwu said: Even if that is the case, what do you wish to do? Deng Yu said: I hope the Duke will expand his virtue and prestige across the Four Seas, and I will exert my strength for the Duke and spread my fame in the annals of history.
