金光明最勝王經疏 5.63

5.63

下第三命師討罰。討者，除也誅也。伐者，征也敗也，欲敗去之。今經作罰，《說文》「罪之小者曰罰。」《廣雅》「罰，折伏也。」今既興兵，應為伐字。或彼但興念未集兵戈，此王興師欲折伏之，故為罰也。

Below is the third part, commanding his forces to punish and attack. Tao means to remove or execute. Fa means to campaign against or defeat, wishing to defeat and drive them off. In the present sūtra it is written as 'punish' (fa 罰). The Shuowen says: 'A minor offense is called fa.' The Guangya says: 'Fa means to subdue.' Now, since troops are mobilized, it should be the character 'attack' (fa 伐). Or it may be that the enemy merely gave rise to the thought and had not yet gathered weapons, so this king raised an army wishing to subdue them; therefore it is written as 'punish' (fa 罰).
