《后汉书·列传·李陈庞陈桥列传》
那么善吏知道奉公之，恶者懂得营私的祸，胡马可不窥长城，塞下没有候望之患了。 
则善吏知奉公之祐，恶者觉营私之祸，胡马可不窥长城，塞下无候望之患矣。
Then good officials will know to obey the law, and wicked ones will understand the consequences of engaging in corruption. The barbarian cavalry will not dare to violate boundaries, and there will be no need to station guards along the frontier.
