Shabbat 19B

לא יגמור. ורבי אלעזר אמר: רבי אלעזר היא. דתנן: חלות דבש שריסקן בערב שבת ויצאו מעצמן ⁠— אסור, ורבי אלעזר מתיר.

He may not finish. And the amora R' Elazar said: Our Mishnah is in accordance with the opinion of R' Elazar the tanna. As we learned in a Mishnah: With regard to honeycombs that he crushed on Friday and the honey came out on its own on Shabbat day, it is prohibited to eat the honey, like anything that was prepared on Shabbat. And R' Elazar permits eating it on Shabbat.

ורבי יוסי בר חנינא מאי טעמא לא אמר כרבי אלעזר? אמר לך, התם הוא דמעיקרא אוכל ולבסוף אוכל, הכא מעיקרא אוכל והשתא משקה. ורבי אלעזר אמר לך: הא שמעינן ליה לרבי אלעזר דאפילו זיתים וענבים נמי שרי. דהא כי אתא רב הושעיא מנהרדעא, אתא ואייתי מתניתא בידיה: זיתים וענבים שריסקן מערב שבת ויצאו מעצמן ⁠— אסורין. רבי אלעזר ורבי שמעון מתירין. ורבי יוסי בר חנינא ברייתא לא שמיע ליה.

The Talmud asks: And R' Yosei bar Ḥanina, what is the reason he did not say in accordance with the explanation of R' Elazar? Apparently, R' Elazar’s explanation in the Mishnah is more accurate. The Talmud answers: R' Yosei could have said to you that there, in the case of the honeycombs, it is food from the beginning and it is food at the end, as honey is considered food. Therefore, there was no squeezing of liquid from food at all. However, here, in all of the cases in the Mishnah, from the beginning they were food and now they became liquid, and that is the definition of squeezing. And R' Elazar could have said to you in response to this assertion: We heard that R' Elazar permitted olives and grapes as well. As when Rav Hoshaya from Neharde’a came, he came and brought a baraita with him, in which it was taught: Olives and grapes that he crushed from Friday and the liquids seeped out on their own, the liquids are prohibited. R' Elazar and R' Shimon permit those liquids. The Talmud answers that R' Yosei bar R' Ḥanina did not know this baraita.
