四分律比丘含注戒本 1.35

1.35

The Buddha said: 'This refers to offenses committed that have not yet been repented. There are two kinds of wise persons: those who can see when they have an offense, and those who, seeing an offense, can repent of it in accordance with the Dharma. If one wishes to repent, he should approach a pure bhikṣu, state the name of the offense, and having cleared it in accordance with the Dharma, only then is he permitted to hear the precepts. Even if one has doubts about an offense, it is also stated like this. If the entire saṃgha has equally committed offenses and there is no one before whom to repent, then without asking whether it is known or doubted, make a motion to repent and then recite.'
