四分律行事鈔資持記 2.1237

2.1237

五十。（六群有緣在軍中觀鬪力，一人彼箭射舁歸招譏故制。）此戒因前而制。疏云：既有緣至，應坐說法；後看合戰，為刃所中；犯同於初。（即觀陣戒。）不犯亦同前戒，故文不列。

Fifty. (The ṣaḍvargika had business and were in the army watching the combat strength; one was shot by the enemy's arrow and carried back, incurring censure; hence it was prohibited.) This precept was established because of the preceding one. The Commentary says: "Since they had business to go there, they should have sat down and expounded the Dharma; later watching the battle, he was struck by a weapon; the violation is the same as the first (that is, the precept on watching the battle formation)." The exceptions are also the same as the preceding precept, so the text does not list them.
