Visuddhimagga II-92

Yathāvuttesu pana ṭhapetvā tecīvarikaṅgaṃ sesāni dvādasa sāmaṇerānaṃ, satta sikkhamānasāmaṇerīnaṃ veditabbāni.

如前述的十三支中，除去三衣支，其它的是沙弥的十二支。（在比丘尼的八支中除三衣支）其它的当知为式叉摩那及沙弥尼的七支。

Ñ(II,92): Except for the triple-robe-wearer's practice all the other twelve as stated should be understood to be for novices, and all the other seven for female probationers and female novices.

Upāsakaupāsikānaṃ pana ekāsanikaṅgaṃ, pattapiṇḍikaṅganti imāni dve patirūpāni ceva sakkā ca paribhuñjitunti dve dhutaṅgānīti evaṃ byāsato dvecattālīsa hontīti ayaṃ samāsabyāsato vaṇṇanā.

优婆塞和优婆夷适合受持一坐食支和一钵食支二支，所以仅有二头陀支。这就是各别而言共有四十二（支）。

这是总与别的解释。

Ñ: The two, namely, the one-sessioner's practice and the bowl-food-eater's practice, are proper for male and female lay followers to employ. In this way there are two ascetic practices. This is the commentary 'as to groups and also singly'.
