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.

[If] an idolater was found standing beside a wine cistern: if he has a lien (lit., a loan) upon it, it is prohibited; if he does not have a lien upon it, it is permitted. [If] he fell into the cistern and came out, or he measured it with a reed, [or] he flicked out a hornet with the reed, or if he was tapping on top of a foaming barrel —- all these [cases] were actual incidents, and they said it should be sold. R’ Shimon, however, permits. [If] he took a barrel and threw it in his anger into the cistern, this was [once] an incident and they declared [it] fit.

[If] one prepares an idolater’s wine in purity, and he places it in his domain in a house which opens onto a public domain —- [if it is] in a city which has idolaters and Jews in it, it is permitted; [but] in a city which is entirely idol worshipers, it is forbid-den, unless he appoints a watchman. The watch- man need not be constantly present and guarding —- even if he leaves and returns, it is permitted. R’ Shimon ben Elazar says: All idolatrous domains are one.
