Dharmaguptaka-vinaya 15.115

15.115

爾時佛在舍衛國祇樹給孤獨園。爾時六群比丘時有因緣至軍中宿，時諸居士見自相謂言：「我等為恩愛故在此宿耳！而此沙門復在此何為耶？」爾時諸比丘聞，中有少欲知足、行頭陀、樂學戒、知慚愧者，嫌責六群比丘言：「世尊制戒有時因緣乃得至軍中，汝等云何乃於軍中止宿耶？」爾時諸比丘往至世尊所，以此因緣具白世尊。世尊以此因緣集比丘僧，呵責六群比丘：「汝所為非，非威儀、非沙門法、非淨行、非隨順行，所不應為。云何，六群比丘！有時因緣得至軍中，汝等何事乃在軍中宿耶？」世尊以無數方便呵責六群比丘已，告諸比丘：「此癡人！多種有漏處，最初犯戒。自今已去與比丘結戒，集十句義乃至正法久住，欲說戒者當如是說：若比丘有因緣，聽至軍中二宿、三宿，過者，波逸提。」

At that time, the Buddha was staying in Śrāvastī, at the Jetavana Anāthapiṇḍadārāma. At that time, the group-of-six bhikṣus, having an occasion of circumstance, went to lodge overnight in the army. Householders saw them and said among themselves: 'We lodge here for the sake of affection and love, but what are these śramaṇas doing here again?' The bhikṣus heard this, and among them those of few desires, contented, practicing dhūta, delighting in training in the precepts, and knowing shame, reproached the group-of-six bhikṣus, saying: 'The Bhagavat laid down the precept that only on an occasion of circumstance may one go to the army; how could you stay overnight in the army?' Then the bhikṣus went to the Bhagavat and reported this matter fully to the Bhagavat. On this account the Bhagavat assembled the saṅgha of bhikṣus and rebuked the group-of-six bhikṣus: 'What you have done is improper, not deportment, not the Dharma of a śramaṇa, not pure conduct, not compliant conduct, what should not be done. Why, bhikṣus of the group of six, when there is an occasion of circumstance allowing one to go to the army, for what reason did you lodge overnight in the army?' Having rebuked the group-of-six bhikṣus with countless expedients, the Bhagavat addressed the bhikṣus: 'These foolish men have produced many kinds of āsrava-bases, being the first to violate the precept. From this day forward, I lay down the precept for the bhikṣus, gathering the ten objectives up to the long endurance of the true Dharma. Those who wish to recite the precept should recite it thus: "If a bhikṣu has an occasion of circumstance, he is permitted to go to the army for two nights or three nights; if he exceeds that, it is a pāyattika."'
