Rabbi Abbahu says: There are three sins before whose transgressors the curtain [hapargod] between the world and the Divine Presence is not locked; their sins reach the Divine Presence. They are: Verbal mistreatment, robbery, and idol worship. Mistreatment, as it is stated: “And a plumb line in His hand”; robbery, as it is stated: “Violence and robbery are heard in her, they are before Me continually” (Jeremiah 6:7); idol worship, as it is stated: “A people that angers Me before Me continually; that sacrifice in gardens, and burn incense upon bricks” (Isaiah 65:3).
§ Apropos the topic of verbal mistreatment, we learned in a mishna there (Kelim 5:10): If one cut an earthenware oven widthwise into segments, and placed sand between each and every segment, Rabbi Eliezer deems it ritually pure. Because of the sand, its legal status is not that of a complete vessel, and therefore it is not susceptible to ritual impurity. And the Rabbis deem it ritually impure, as it is functionally a complete oven.
(ג) ועל דרך ענין זה שעוררתיך, בני, עליו אפרש לך אגדה אחת שהיא בבבא מציעא בסוף פרק הזהב (נט, ב) גבי ההוא מעשה דרבי אליעזר הגדול בתנורו של עכנאי, המתמהת כל שומעה. אמרו שם אשכחה רבי נתן לאליהו וכו' אמר לה מאי עביד קדשא בריך הוא בההיא שעתא? אמר לה חיך ואמר נצחוני בני, כלומר שהיה הקדוש ברוך הוא שמח על שהיו בניו הולכים בדרך התורה ובמצותה להטות אחרי רבים, ומה שאמר נצחוני בני חלילה להיות נצחון לפניו ברוך הוא, אבל פרוש הדבר הוא על ענין זה, שבמחלקת הזה שהיתה לרבי אליעזר עם חבריו האמת היתה כרבי אליעזר וכדברי הבת קול שהכריעה כמותו, ואף על פי שהיה האמת אתו בזה, ביתרון פלפולו על חבריו לא ירדו לסוף דעתו, ולא רצו להודות לדבריו אפילו אחר בת קול, והביאו ראיה מן הדין הקבוע בתורה שצותנו ללכת אחרי הרבים לעולם, בין יאמרו אמת או אפילו טועים, ועל זה השיב הבורא ברוך הוא נצחוני בני, כלומר, אחר שהם נוטים מדרך האמת, שרבי אליעזר הוא היה מכוין בזה את האמת, והם באים עליו מכח מצות התורה שצויתים לשמע אל הרב לעולם, אם כן על כל פנים יש להודות להם בפעם הזאת כדבריהם שתהיה האמת נעדרת, והרי זה כאלו בעל האמת נצוח.
(3) By way of this idea that I have raised for you, my son - through it, will I explain to you a certain homelitical teaching, which is in the end of the chapter [entitled] HaZahav in Bava Metzia 59b, regarding the story of Rabbi Eliezer the Great and the "oven of Achnai," which bewilders all who hear it. They said there, "Rabbi Natan met Eliyahu, etc. He said to him, 'What did the Holy One, Blessed be He, do in that hour?' He said to him, 'He smiled and said, "My sons have vanquished Me..."'" - meaning that the Holy One, blessed be He, was happy that His sons were walking in the way of the Torah and its commandment, to incline after the many. And that which He said, "My sons have vanquished Me," God forbid that there is any victory before Him, blessed be He. Rather, the explanation about this idea is that in the debate of Rabbi Eliezer with his colleagues, the truth was with Rabbi Eliezer; and like the words of the heavenly voice (bat kol) that decided like him. But even though the truth was with him about this - because of his greater analysis over his colleagues - they could not completely fathom his opinion. And [so] they did not want to concede to him even after the heavenly voice; and they brought a proof from the law set in the Torah that commanded us to always go after the many - whether they say the truth or whether they are mistaken. And about this was the response of the Creator, blessed be He, "My sons have vanquished Me." Meaning, since they turned away from the true path - for Rabbi Eliezer had surmised the truth about this - and they came upon him from the power of the Torah commandment that I commanded them to always listen to the majority; if so, one must nonetheless concede to them this time - like their words - that the truth be absent. And behold, it is as if the Master of truth was defeated.
