《汉书·志·刑法志》
到元帝刚被立为皇帝，就下令说： 法令，是用来抑制强暴扶助弱小，是希望人们难以触犯而容易避免。
至元帝初立，乃下诏曰： 夫法令者，所以抑暴扶弱，欲其难犯而易避也。
When Emperor Yuan was first enthroned, he gave an order: Law and decree are used to suppress the strong and assist the weak. It is hoped that people will find it difficult to break the law and it will be easy to avoid it.
