One may buy a trodden winepress from an idolater, even though he takes with his hand and places in the mound. And it does not become nesech-wine until it descends into the cistern. [If] it descended to the cistern, that which is in the cistern is prohibited, and the remainder is permitted.

One may tread with an idolater in the winepress, but one may not harvest grapes with him. [If] a Jew processes [his fruits] in a state of tumah, one may not tread nor may one harvest grapes with him; but one may transport barrels to the winepress with him, and carry away from the winepress with him. [If] a baker processes in tumah, one may not knead or roll dough with him; but one may transport bread to the retailer with him.
