Avodah Zarah 4:8 - 4:9

גת בעוטה – that the idolater had trampled and stamped.

אע"פ שהוא נוטל בידו – grapes from the wine and place them on the pile (i.e., the place on the altar where the ashes are piled up), the place of the gathering of the grapes that is made like a heap that is called תפוח/grape-heap, and our Tanna/teacher holds that it does not become libation wine until it flows down to the cistern and according to the hour, he becomes excited and returns and worships it. But this is the earliest version of the Mishnah and it is not Halakha, but rather, since the wine began to be drawn, it became libation wine.

מה שבבור אסור – if an idolater would come in contact with it afterwards.

דורכין עם העכו"ם בגת – and we don’t say that he is making a living with what is prohibited from deriving benefit, for this Tanna/thinks [that even] with drinking, it is permitted as long as he doesn’t go down into the cistern. But there isn’t anything concerning causing ritual defilement for from the time when the idolater treads upon them [a little bit], they were ritually defiled, so it is found that the Israelite did not cause the ritual defilement.

אבל לא בוצרין עמו – because he places them into a ritually impure vat for wine pressing. For the idolater defiles the grapes through his contact and the Israelite who cuts with him causes ritual defilement. But this Tanna/teacher holds that it is forbidden to cause ritual defilement for non-holy produce that is in the Land of Israel, even if they belong to the idolater. But the Halakha is not according to this Mishnah for we hold that since the wine began to be drawn, it became libation wine, therefore, we do not tread with the idolater in the vat for wine pressing. And we hold that it is permissible to cause ritual from produce, there is nothing in this. But however, an Israelite who harvests his vineyard ab initio, the idolater should not take with him, even to bring the grapes to the vat, because we say, “go around Nazirite, etc. (that you may not come near the vineyard” – see Numbers Rabbah 6:10).

וישראל העושה פירותיו בטומאה – he commits a sin because he defiles the Priest’s Due and Tithes that are within them. Therefore, it is forbidden to assist him in order that he become accustomed to this.

אבל מוליכין עמו – an empty barrel to the vat, and he brings it with him filled barrels from the winepress, for what has happened has happened for after they have been ritually defiled, it is permissible to put the wine in impure barrels.
