פירוש על עבודה זרה 129:8

Abaye solves the problem by just reading the baraita into the mishnah.

Rava says that the agreement was different in the two cases. In the mishnah he removes a lump sum of jugs for a lump sum of money. Even if one of them is yayin nesekh, he was not specifically hired to carry that jug. But in the baraita, he was told to remove each jug for a perutah. Therefore, the wages he received for moving the jug of yayin nesekh are prohibited.
