The Talmud

שׁוּב מַעֲשֶׂה בְּגוֹי אֶחָד שֶׁבָּא לִפְנֵי שַׁמַּאי. אָמַר לוֹ: גַּיְּירֵנִי עַל מְנָת שֶׁתְּלַמְּדֵנִי כׇּל הַתּוֹרָה כּוּלָּהּ כְּשֶׁאֲנִי עוֹמֵד עַל רֶגֶל אַחַת! דְּחָפוֹ בְּאַמַּת הַבִּנְיָן שֶׁבְּיָדוֹ. בָּא לִפְנֵי הִלֵּל, גַּיְירֵיהּ. אָמַר לוֹ: דַּעֲלָךְ סְנֵי לְחַבְרָךְ לָא תַּעֲבֵיד — זוֹ הִיא כׇּל הַתּוֹרָה כּוּלָּהּ, וְאִידַּךְ פֵּירוּשָׁהּ הוּא, זִיל גְּמוֹר.

Another time a non-Jew came before Shammai and said, "I will convert if you can teach me the entire Torah while I stand on one foot." Shammai pushed the non-Jews aside with the ruler that was in his hand. The non-Jew came before Hillel and Hillel converted him saying, "What is hateful to you, do not do to your neighbor, that is the entire Torah, the rest is just commentary, now go and study."

Shabbat 31a:6 · Sefaria Community Translation

מַרְגְּלָא בְּפוּמֵּיהּ דְּרָבָא: תַּכְלִית חָכְמָה — תְּשׁוּבָה וּמַעֲשִׂים טוֹבִים, שֶׁלֹּא יְהֵא אָדָם קוֹרֵא וְשׁוֹנֶה וּבוֹעֵט בְּאָבִיו וּבְאִמּוֹ וּבְרַבּוֹ וּבְמִי שֶׁהוּא גָּדוֹל מִמֶּנּוּ בְּחָכְמָה וּבְמִנְיָן, שֶׁנֶּאֱמַר: ״רֵאשִׁית חָכְמָה יִרְאַת ה׳ שֵׂכֶל טוֹב לְכָל עוֹשֵׂיהֶם״. ״לָעוֹשִׂים״ לֹא נֶאֱמַר, אֶלָּא ״לְעוֹשֵׂיהֶם״ — לָעוֹשִׂים לִשְׁמָהּ וְלֹא לָעוֹשִׂים שֶׁלֹּא לִשְׁמָהּ. וְכָל הָעוֹשֶׂה שֶׁלֹּא לִשְׁמָהּ, נוֹחַ לוֹ שֶׁלֹּא נִבְרָא.

It was a favourite saying of Raba : The goal of wisdom is repentance and good works; so that a man shall not read [Torah] and study [Mishnah] and then contradict his father or mother or teacher or anybody greater than he in knowledge and number [of years]; as it is said, "The fear of the Lord is the beginning of wisdom, a good understanding have all that do thereafter" (Ps. cxi. 10). "All that learn" is not said here, but "all that do thereafter," i.e. they that practise Torah for its own sake, but not they that practise Torah not for its own sake. As for him who does not fulfil the Torah for its own sake, it were better had he never been created.

Berakhot 17a:11 · Tractate Berakot by A. Cohen, Cambridge University Press, 1921

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!״

R. Yehoshua stood on his feet and said “[The Torah] is not in heaven,” (Deuteronomy 30:12). What does "[The Torah] is not in heaven" mean? R. Yirmiyah said: “That the Torah was already given at Sinai, we do not pay attention to a heavenly voice, since You already wrote at Sinai in the Torah, “After the majority to incline,” (Exodus 23:2). R. Natan met the prophet Elijah and 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 defeated Me, My sons have defeated Me.”

אָמַר לְפָנָיו: רִבּוֹנוֹ שֶׁל עוֹלָם, הַרְאֵהוּ לִי, אָמַר לוֹ: חֲזוֹר לַאֲחוֹרֶךָ. הָלַךְ וְיָשַׁב בְּסוֹף שְׁמוֹנֶה שׁוּרוֹת, וְלֹא הָיָה יוֹדֵעַ מָה הֵן אוֹמְרִים, תָּשַׁשׁ כֹּחוֹ. כֵּיוָן שֶׁהִגִּיעַ לְדָבָר אֶחָד, אָמְרוּ לוֹ תַּלְמִידָיו: רַבִּי, מִנַּיִן לָךְ? אָמַר לָהֶן: ״הֲלָכָה לְמֹשֶׁה מִסִּינַי״, נִתְיַישְּׁבָה דַּעְתּוֹ.

He said before Him, "Master of the Universe! Show him to me." He said to him, "Turn backwards." He went and sat at the end of eight rows [of students in Rabbi Akiva's Beit Midrash], and he did not know what they were talking [about]. He got upset. When he [Rabbi Akiva] got to [teaching] something, his students said to him, "Teacher, from where do you learn this?" He said to them, "It is a law [that was taught] to Moshe at Sinai." He calmed down.
