Pratimoksha of the Dharmaguptakas 1.60

1.60

「若比丘！道路行得羊毛，若無人持，得自持，乃至三由旬。若無人持，自持，過三由旬，尼薩耆波逸提。

If a monk going along the road, obtain (whether by gift or otherwise) a sheep fleece, he may take as much of it as he requires; and if there be no one to carry it, he may carry it himself for a distance of three yojanas, but if he exceeds this distance, it is nissaggiya pācittiya.
