הוּא תַּנּוּר שֶׁל עַכְנַאי... תָּנָא: בְּאוֹתוֹ הַיּוֹם הֵשִׁיב רַבִּי אֱלִיעֶזֶר כׇּל תְּשׁוּבוֹת שֶׁבָּעוֹלָם, וְלֹא קִיבְּלוּ הֵימֶנּוּ.
§ And this is known as the oven of akhnai.... The Sages taught: On that day, when they discussed this matter, Rabbi Eliezer answered all possible answers in the world to support his opinion, but the Rabbis did not accept his explanations from him.
אָמַר לָהֶם: אִם הֲלָכָה כְּמוֹתִי – חָרוּב זֶה יוֹכִיחַ. נֶעֱקַר חָרוּב מִמְּקוֹמוֹ מֵאָה אַמָּה, וְאָמְרִי לַהּ: אַרְבַּע מֵאוֹת אַמָּה. אָמְרוּ לוֹ: אֵין מְבִיאִין רְאָיָה מִן הֶחָרוּב. חָזַר וְאָמַר לָהֶם: אִם הֲלָכָה כְּמוֹתִי – אַמַּת הַמַּיִם יוֹכִיחוּ. חָזְרוּ אַמַּת הַמַּיִם לַאֲחוֹרֵיהֶם. אָמְרוּ לוֹ: אֵין מְבִיאִין רְאָיָה מֵאַמַּת הַמַּיִם. חָזַר וְאָמַר לָהֶם:
After failing to convince the Rabbis logically, Rabbi Eliezer said to them: If the halakha is in accordance with my opinion, this carob tree will prove it. The carob tree was uprooted from its place one hundred cubits, and some say four hundred cubits. The Rabbis said to him: One does not cite halakhic proof from the carob tree. Rabbi Eliezer then said to them: If the halakha is in accordance with my opinion, the stream will prove it. The water in the stream turned backward and began flowing in the opposite direction. They said to him: One does not cite halakhic proof from a stream.
Halakha (also spelled halacha) = Jewish Law
What happened each time Rabbi Eliezer tried to convince the other rabbis in the Beit Midrash?
אִם הֲלָכָה כְּמוֹתִי – כּוֹתְלֵי בֵּית הַמִּדְרָשׁ יוֹכִיחוּ. הִטּוּ כּוֹתְלֵי בֵּית הַמִּדְרָשׁ לִיפּוֹל. גָּעַר בָּהֶם רַבִּי יְהוֹשֻׁעַ, אָמַר לָהֶם: אִם תַּלְמִידֵי חֲכָמִים מְנַצְּחִים זֶה אֶת זֶה בַּהֲלָכָה, אַתֶּם מָה טִיבְכֶם? לֹא נָפְלוּ מִפְּנֵי כְבוֹדוֹ שֶׁל רַבִּי יְהוֹשֻׁעַ, וְלֹא זָקְפוּ מִפְּנֵי כְבוֹדוֹ שֶׁל רַבִּי אֱלִיעֶזֶר, וַעֲדַיִן מַטִּין וְעוֹמְדִין. חָזַר וְאָמַר לָהֶם: אִם הֲלָכָה כְּמוֹתִי – מִן הַשָּׁמַיִם יוֹכִיחוּ. יָצָאתָה בַּת קוֹל וְאָמְרָה: מָה לָכֶם אֵצֶל רַבִּי אֱלִיעֶזֶר, שֶׁהֲלָכָה כְּמוֹתוֹ בְּכׇל מָקוֹם. עָמַד רַבִּי יְהוֹשֻׁעַ עַל רַגְלָיו וְאָמַר: ״לֹא בַשָּׁמַיִם הִיא!״ מַאי ״לֹא בַּשָּׁמַיִם הִיא״? אָמַר רַבִּי יִרְמְיָה: שֶׁכְּבָר נִתְּנָה תּוֹרָה מֵהַר סִינַי, אֵין אָנוּ מַשְׁגִּיחִין בְּבַת קוֹל, שֶׁכְּבָר כָּתַבְתָּ בְּהַר סִינַי בַּתּוֹרָה ״אַחֲרֵי רַבִּים לְהַטֹּת״. אַשְׁכְּחֵיהּ רַבִּי נָתָן לְאֵלִיָּהוּ, אֲמַר לֵיהּ: מַאי עָבֵיד קוּדְשָׁא בְּרִיךְ הוּא בְּהַהִיא שַׁעְתָּא? אֲמַר לֵיהּ: קָא חָיֵיךְ וְאָמַר, ״נִצְּחוּנִי בָּנַי! נִצְּחוּנִי בָּנַי!״
Rabbi Eliezer then said to them: If the halakha is in accordance with my opinion, the walls of the beit midrash will prove it. The walls of the beit midrash leaned inward and began to fall. Rabbi Yehoshua scolded the walls and said to them: If Torah scholars are contending with each other in matters of halakha, what is the nature of your involvement in this dispute? The Gemara relates: The walls did not fall because of the deference due Rabbi Yehoshua, but they did not straighten because of the deference due Rabbi Eliezer, and they still remain leaning. Rabbi Eliezer then said to them: If the halakha is in accordance with my opinion, Heaven will prove it. A Divine Voice emerged from Heaven and said: Why are you differing with Rabbi Eliezer, as the halakha is in accordance with his opinion in every place that he expresses an opinion? Rabbi Yehoshua stood on his feet and said: It is written: “It is not in heaven” (Deuteronomy 30:12). The Gemara asks: What is the relevance of the phrase “It is not in heaven” in this context? Rabbi Yirmeya says: Since the Torah was already given at Mount Sinai, we do not regard a Divine Voice, as You already wrote at Mount Sinai, in the Torah: “After a majority to incline” (Exodus 23:2).
Beit Midrash = House of Study
What was different this time that Rabbi Eliezer said something would happen from the times before?
What does "It is not in heaven" mean?
Did rabbi Eliezer make an impact?
אמר רבי יהודה בר' אלעאי: כשעמדו ישראל על הים, היו השבטים מדיינים אלה עם אלה, זה אומר: אני יורד תחלה, וזה אומר: אני יורד תחלה. קפץ נחשון לתוך גלי הים וירד ועליו. אמר דוד (שם סט): הושיעני אלקים כי באו מים עד נפש...
Rabbi Yehudah ben Elai said: When Israel was at the sea, the tribes were arguing with each other. One tribe said: 'I will go down first [into the sea]', and the other tribe said 'I will go down first.' Nachshon jumped first into the waves of the sea and went down, as David said, "Deliver me, O God, for the waters have reached my neck."
