《后汉书·列传·独行列传》
从前是母亲的儿子，现在是皇上的臣子，大义不得顾私恩，毁忠节，只当万死，无法抵罪。 
昔为母子，今为王臣，义不得顾私恩、毁忠节，唯当万死，无以塞罪。 
In the past, I was my mother's son, but now I am the emperor's subject. I can not let personal affection influence justice and ruin my loyalty. I deserve to be executed ten thousand times, and can not make up for my crime."
