四分律比丘含注戒本 1.293

1.293

諸大德！我已說十三僧伽婆尸沙法。九戒初犯，四至三諫。若比丘犯一一法，知而覆藏，應強與波利婆沙。行波利婆沙竟，增上與六夜摩那埵。行摩那埵已，應與出罪。應二十僧中出是比丘罪。若少一人，不滿二十眾出，是比丘罪不得除，諸比丘亦可訶。此是時。

Venerables, I have recited the thirteen saṃghāvaśeṣa dharmas. Nine precepts are offenses upon the initial commission; four become so upon the third admonition. If a bhikṣu commits any one dharma and knowingly conceals it, he must be compelled to undergo parivāsa. Having completed parivāsa, he must additionally be given six nights of mānatva. Having performed mānatva, he should be granted rehabilitation. This bhikṣu's offense must be rehabilitated amidst a Saṃgha of twenty. If there is even one person fewer, so that the assembly does not reach twenty, the offense of this bhikṣu cannot be removed, and the bhikṣus are also blameworthy. This is the proper procedure.
