四分律比丘含注戒本 2.55

2.55

The Buddha was in Rājagṛha. There were bhikṣus undergoing parivāsa and mānatva sitting in the lower rows. The group of six bhikṣus spoke of the offenses they had committed to white-robed laypeople. The offenders and the other bhikṣus were all ashamed. Bhikṣus brought up the fault, and therefore the Buddha rebuked them and formulated [this precept].
