וְרַבִּי מֵאִיר, הֵיכִי גְּמַר תּוֹרָה מִפּוּמֵּיהּ דְּאַחֵר? וְהָאָמַר רַבָּה בַּר בַּר חָנָה אָמַר רַבִּי יוֹחָנָן: מַאי דִּכְתִיב: ״כִּי שִׂפְתֵי כֹהֵן יִשְׁמְרוּ דַעַת וְתוֹרָה יְבַקְשׁוּ מִפִּיהוּ כִּי מַלְאַךְ ה׳ צְבָאוֹת הוּא״. אִם דּוֹמֶה הָרַב לְמַלְאַךְ ה׳ צְבָאוֹת — יְבַקְּשׁוּ תּוֹרָה מִפִּיהוּ, וְאִם לָאו — אַל יְבַקְּשׁוּ תּוֹרָה מִפִּיהוּ! אָמַר רֵישׁ לָקִישׁ: רַבִּי מֵאִיר — קְרָא אַשְׁכַּח וּדְרַשׁ: ״הַט אׇזְנְךָ וּשְׁמַע דִּבְרֵי חֲכָמִים וְלִבְּךָ תָּשִׁית לְדַעְתִּי״, ״לְדַעְתָּם״ לֹא נֶאֱמַר, אֶלָּא ״לְדַעְתִּי״. רַב חֲנִינָא אָמַר מֵהָכָא: ״שִׁמְעִי בַת וּרְאִי וְהַטִּי אׇזְנֵךְ וְשִׁכְחִי עַמֵּךְ וּבֵית אָבִיךְ וְגוֹ׳״. קָשׁוּ קְרָאֵי אַהֲדָדֵי? לָא קַשְׁיָא: הָא בְּגָדוֹל, הָא בְּקָטָן. כִּי אֲתָא רַב דִּימִי, אֲמַר, אָמְרִי בְּמַעְרְבָא: רַבִּי מֵאִיר אֲכַל תַּחְלָא, וּשְׁדָא שִׁיחְלָא לְבָרָא. דָּרֵשׁ רָבָא: מַאי דִּכְתִיב: ״אֶל גִּנַּת אֱגוֹז יָרַדְתִּי לִרְאוֹת בְּאִבֵּי הַנָּחַל וְגוֹ׳״, לָמָּה נִמְשְׁלוּ תַּלְמִידֵי חֲכָמִים לֶאֱגוֹז — לוֹמַר לָךְ: מָה אֱגוֹז זֶה, אַף עַל פִּי שֶׁמְּלוּכְלָךְ בְּטִיט וּבְצוֹאָה — אֵין מַה שֶּׁבְּתוֹכוֹ נִמְאָס; אַף תַּלְמִיד חָכָם, אַף עַל פִּי שֶׁסָּרַח — אֵין תּוֹרָתוֹ נִמְאֶסֶת.
The Gemara poses a question: And Rabbi Meir, how could he learn Torah from the mouth of Aḥer? But didn’t Rabba bar bar Ḥana say that Rabbi Yoḥanan said: What is the meaning of that which is written: “For the priest’s lips should keep knowledge, and they should seek Torah from his mouth; for he is an angel of the Lord of hosts” (Malachi 2:7)? The verse teaches: If the rabbi is similar to an angel of the Lord of hosts, perfect in his ways, they should seek Torah from his mouth; but if not, they should not seek Torah from his mouth.
Reish Lakish said: Rabbi Meir found a verse and interpreted it homiletically: “Incline your ear, and hear the words of the wise, and apply your heart to My knowledge” (Proverbs 22:17). It does not state “to their knowledge,” but “to My knowledge.” In other words, one must listen to the words of the Sages, despite their flaws, provided that their opinion concurs with that of God...
The Gemara asks: If so, the verses contradict each other, for one source states that one may learn only from a scholar who is perfect in his ways, while the other indicates that it is permitted even to learn from one whose character is flawed. The Gemara answers: This is not difficult. This case, in which it is permitted to learn from a flawed scholar, is referring to an adult; whereas that case, which prohibits doing so, is referring to a minor, who should learn only from a righteous person, so that his ways are not corrupted by a teacher with flawed character.
When Rav Dimi came from Eretz Yisrael to Babylonia, he said: In the West, Eretz Yisrael, they say: Rabbi Meir ate a half-ripe date and threw the peel away. In other words, he was able to extract the important content from the inedible shell. Rava taught: What is the meaning of that which is written: “I went down into the garden of nuts, to look at the green plants of the valley” (Song of Songs 6:11)? Why are Torah scholars compared to nuts? To tell you: Just as this nut, despite being soiled with mud and excrement, its content is not made repulsive, as only its shell is soiled; so too a Torah scholar, although he has sinned, his Torah is not made repulsive.
