《宋书·列传·卷一百》
况且山野田原是无人居住的地方。山丘陇田不是寻常道路经历过的地方，想加以防守不能和村庄相比，寻名责实，盗窃方与打劫不同，那么军中不援救另外的部队的罪行，应该是比这些强盗罪重一些。
且山原为无人之乡，丘垄非恆途所践，至于防救，不得比之村郭。督实效名，理与劫异，则符伍之坐，居宜降矣。
Moreover, mountainous and rural areas are sparsely populated. Hills and fields are not commonly patrolled, and it is impossible to defend them like villages. If we examine the facts and distinguish between different crimes, tomb raiding is clearly different from robbing. Therefore, military personnel who fail to assist other units should be punished more severely than tomb raiders.
