Text Excerpt
ורב יוסף אמר: רבי שמעון ורבנן בפלוגתא דרבי יוחנן בן נורי ורבנן קא מיפלגי. דתנן: שמן שצף על גבי יין, ונגע טבול יום בשמן — לא פסל אלא שמן בלבד, ורבי יוחנן בן נורי אומר: שניהן חיבורין זה לזה.
And Rav Yosef said: In fact we are dealing here with a single alleyway, and R' Shimon and the Rabbis disagree about the same point of dispute between R' Yoḥanan ben Nuri and the Rabbis. As we learned in a Mishnah: If teruma oil was floating on the surface of wine, and one who immersed during the day, touched the oil, he disqualified only the oil alone. However, he did not disqualify the wine, because it is considered separate from the oil. Only the oil is disqualified, and it does not render other items ritually impure. And R' Yoḥanan ben Nuri says: They are both connected to each other and are considered as one, so the wine is also ritually impure.
רבנן — כרבנן, ורבי שמעון — כרבי יוחנן בן נורי.
The Talmud explains: The opinion of the Rabbis in our Mishnah is in accordance with the opinion of the Rabbis in the other Mishnah, who maintain that wine and oil are not connected and therefore cannot be used together in an eiruv, and the opinion of R' Shimon is in accordance with the opinion of R' Yoḥanan ben Nuri, who holds that wine and oil are connected, and may be used together in an eiruv.
תניא, רבי אליעזר בן תדאי אומר: אחד זה ואחד זה צריכין לערב. ואפילו לזה ביין ולזה ביין?
It was taught in a baraita: R' Eliezer ben Taddai says: In both this case, of wine and wine, and that case, of wine and oil, they must establish an eiruv. The Talmud expresses wonder: Did he say this even if the partnership is with this one in wine and also with the other one in wine? Why should these partnerships not be sufficient to consider the items merged?
