擔羊毛過三由旬戒第十六　然出家之人躬擔羊毛。順俗而行跡同。凡辟動越威儀。招譏損道。故制不聽。所以復開。三由旬者有持之利。無以存濟。復開三過擔結罪　別緣有四。一貴羊毛除賤故。律云。頭頂足毛不犯。祇云。駝猪等毛越。二是己物。三自知。祇云。三人共有各持齊九由旬。重擔者俱犯。四過三由旬即犯。已下正戒本。此戒因跋難陀起過。便制此戒。

The sixteenth precept: on carrying sheep wool for more than three yojanas. / Now, for an ordained person to personally carry sheep wool, following worldly ways and acting like common people, impairs deportment, invites ridicule, and damages the Path; hence it was prohibited and not allowed. As for why it was further permitted up to three yojanas, there is the utility of holding it, and without it one cannot sustain oneself; further, carrying it for more than three [yojanas] determines an offense. / There are four specific conditions: 1. Costly sheep wool, excluding cheap kinds; thus the Vinaya states that wool from the head, crown, and feet is no offense; the Mahāsāṃghika says camel and pig hair, etc., incur a transgression; 2. It is one's own property; 3. Knowing it oneself; the Mahāsāṃghika says if three persons share it together and each carries it up to nine yojanas, those carrying the heavy load all commit an offense; 4. Exceeding three yojanas, an offense is immediately committed. Below, the precept text itself. This precept was instituted because Upananda gave rise to the fault.
