This passage lists multiple causes for Jerusalem's destruction: neglect of Torah education for children, failure to recite the Shema morning and evening, failure of Torah scholars to rebuke one another, contempt for Torah scholars, and shaming others in public.
אָמַר רַב יְהוּדָה בְּרֵיהּ דְּרַב שְׁמוּאֵל מִשְּׁמֵיהּ דְּרַב: אֵין הַדְּלֵיקָה מְצוּיָה אֶלָּא בִּמְקוֹם שֶׁיֵּשׁ חִילּוּל שַׁבָּת, שֶׁנֶּאֱמַר: ״וְאִם לֹא תִשְׁמְעוּ אֵלַי לְקַדֵּשׁ אֶת יוֹם הַשַּׁבָּת וּלְבִלְתִּי שְׂאֵת מַשָּׂא וְגוֹ׳ וְהִצַּתִּי אֵשׁ בִּשְׁעָרֶיהָ וְאָכְלָה אַרְמְנוֹת יְרוּשָׁלִַים וְלֹא תִכְבֶּה״. מַאי ״וְלֹא תִכְבֶּה״? אָמַר רַב נַחְמָן בַּר יִצְחָק: בְּשָׁעָה שֶׁאֵין בְּנֵי אָדָם מְצוּיִין לְכַבּוֹתָהּ. אָמַר אַבָּיֵי: לָא חָרְבָה יְרוּשָׁלַיִם אֶלָּא בִּשְׁבִיל שֶׁחִלְּלוּ בָּהּ אֶת הַשַּׁבָּת, שֶׁנֶּאֱמַר: ״וּמִשַׁבְּתוֹתַי הֶעְלִימוּ עֵינֵיהֶם וָאֵחַל בְּתוֹכָם״. אָמַר רַבִּי אֲבָהוּ: לֹא חָרְבָה יְרוּשָׁלַיִם אֶלָּא בִּשְׁבִיל שֶׁבִּיטְּלוּ קְרִיאַת שְׁמַע שַׁחֲרִית וְעַרְבִית, שֶׁנֶּאֱמַר: ״הוֹי מַשְׁכִּימֵי בַבֹּקֶר שֵׁכָר יִרְדֹּפוּ וְגוֹ׳״, וּכְתִיב: ״וְהָיָה כִנּוֹר וָנֶבֶל תּוֹף וְחָלִיל וָיַיִן מִשְׁתֵּיהֶם וְאֵת פּוֹעַל ה׳ לֹא יַבִּיטוּ״, וּכְתִיב: ״לָכֵן גָּלָה עַמִּי מִבְּלִי דָעַת״. אָמַר רַב הַמְנוּנָא: לֹא חָרְבָה יְרוּשָׁלַיִם אֶלָּא בִּשְׁבִיל שֶׁבִּיטְּלוּ בָּהּ תִּינוֹקוֹת שֶׁל בֵּית רַבָּן, שֶׁנֶּאֱמַר: ״שְׁפוֹךְ עַל עוֹלָל בַּחוּץ וְגוֹ׳״. מַה טַּעַם ״שְׁפוֹךְ״ — מִשּׁוּם דְּ״עוֹלָל בַּחוּץ״. אָמַר עוּלָּא: לֹא חָרְבָה יְרוּשָׁלַיִם אֶלָּא מִפְּנֵי שֶׁלֹּא הָיָה לָהֶם בּוֹשֶׁת פָּנִים זֶה מִזֶּה, שֶׁנֶּאֱמַר: ״הוֹבִישׁוּ כִּי תוֹעֵבָה עָשׂוּ גַּם בּוֹשׁ לֹא יֵבוֹשׁוּ וְגוֹ׳״. אָמַר רַבִּי יִצְחָק: לֹא חָרְבָה יְרוּשָׁלַיִם אֶלָּא בִּשְׁבִיל שֶׁהוּשְׁווּ קָטָן וְגָדוֹל, שֶׁנֶּאֱמַר: ״וְהָיָה כָעָם כַּכֹּהֵן״, וּכְתִיב בָּתְרֵיהּ: ״הִבּוֹק תִּבּוֹק הָאָרֶץ״. אָמַר רַב עַמְרָם בְּרֵיהּ דְּרַבִּי שִׁמְעוֹן בַּר אַבָּא, אָמַר רַבִּי שִׁמְעוֹן בַּר אַבָּא, אָמַר רַבִּי חֲנִינָא: לֹא חָרְבָה יְרוּשָׁלַיִם אֶלָּא בִּשְׁבִיל שֶׁלֹּא הוֹכִיחוּ זֶה אֶת זֶה, שֶׁנֶּאֱמַר: ״הָיוּ שָׂרֶיהָ כְּאַיָּלִים לֹא מָצְאוּ מִרְעֶה״. מָה אַיִל זֶה, רֹאשׁוֹ שֶׁל זֶה בְּצַד זְנָבוֹ שֶׁל זֶה, אַף יִשְׂרָאֵל שֶׁבְּאוֹתוֹ הַדּוֹר כָּבְשׁוּ פְּנֵיהֶם בַּקַּרְקַע וְלֹא הוֹכִיחוּ זֶה אֶת זֶה. אָמַר רַבִּי יְהוּדָה: לֹא חָרְבָה יְרוּשָׁלַיִם אֶלָּא בִּשְׁבִיל שֶׁבִּיזּוּ בָּהּ תַּלְמִידֵי חֲכָמִים, שֶׁנֶּאֱמַר: ״וַיִּהְיוּ מַלְעִיבִים בְּמַלְאֲכֵי הָאֱלֹהִים וּבוֹזִים דְּבָרָיו וּמִתַּעְתְּעִים בִּנְבִיאָיו עַד עֲלוֹת חֲמַת ה׳ בְּעַמּוֹ עַד [לְ]אֵין מַרְפֵּא״. מַאי ״עַד לְאֵין מַרְפֵּא״? אָמַר רַב יְהוּדָה אָמַר רַב: כׇּל הַמְבַזֶּה תַּלְמִידֵי חֲכָמִים אֵין לוֹ רְפוּאָה לְמַכָּתוֹ.
Rav Yehuda, son of Rav Shmuel, said in the name of Rav: Fire is only found in a place where there is desecration of Shabbat, as it is stated: “And if you do not heed Me to sanctify the day of Shabbat, and to refrain from carrying burdens and come to the gates of Jerusalem on the day of Shabbat, and I will light a fire in its gates and it will consume the palaces of Jerusalem and it will not be extinguished” (Jeremiah 17:27). The Gemara asks: What is the meaning of: And it will not be extinguished? Rav Naḥman bar Yitzḥak said: Fire will break out at a time when people are not found to extinguish it. Abaye said: Jerusalem was destroyed only because people desecrated the Shabbat in it, as it is stated: “And from My Shabbatot they averted their eyes, and I was profaned among them” (Ezekiel 22:26). Several punishments were decreed to befall Jerusalem as punishment for this transgression. The Gemara suggests additional reasons for the destruction of Jerusalem. Rabbi Abbahu said: Jerusalem was destroyed only because its citizens intentionally omitted recitation of Shema morning and evening, as it is stated: “Woe to those who rise early in the morning and pursue the drink and are aflame from wine until late in the evening” (Isaiah 5:11). And it is written in the continuation of that passage: “And their drinking parties have lyre and lute, drum and flute and wine, and they do not look upon the actions of God, and they do not see His hands’ creations” (Isaiah 5:12). This means that in the morning and evening, when the Jews should have been reciting Shema, they were drinking wine and liquor. And it is written in that passage: “Therefore My nation is being exiled for its ignorance; its honor will die of hunger and its multitudes will be parched with thirst” (Isaiah 5:13). Rav Hamnuna said: Jerusalem was destroyed only because schoolchildren there were interrupted from studying Torah, as it is stated: “And I am filled with the wrath of God, I cannot contain it, pour it onto the infants in the street and onto the gathering of youths together, for men and women alike will be captured, the elderly along with those of advanced years” (Jeremiah 6:11). Rav Hamnuna explains: What is the reason that the wrath is poured? It is because infants are outside in the streets and are not studying Torah. Ulla said: Jerusalem was destroyed only because people had no shame before each other, as it is stated: “They acted shamefully; they have performed abominations, yet they neither were ashamed nor did they know humiliation. Therefore, they will fall among the fallen, they will fail at the time that I punish them, said God” (Jeremiah 6:15). Rabbi Yitzḥak said: Jerusalem was destroyed only because its small and the great citizens were equated. They did not properly value the prominent leaders of their generation, as it is stated: “And the common people were like the priest, the slave like his master, the maidservant like her mistress, the buyer like the seller, the lender like the borrower, the creditor like the one indebted to him” (Isaiah 24:2). And it is written afterward: “The land shall be utterly desolate and completely plundered, for God has said this” (Isaiah 24:3). Rav Amram, son of Rabbi Shimon bar Abba, said that Rabbi Shimon bar Abba said that Rabbi Ḥanina said: Jerusalem was destroyed only because the people did not rebuke one another, as it is stated: “Her ministers were like stags that found no pasture, and they walked without strength before their pursuer” (Lamentations 1:6). Just as this stag turns its head toward the other’s tail when it grazes, and each one feeds on its own, so too, the Jewish people in that generation lowered their faces to the ground and did not rebuke one another. Rabbi Yehuda said: Jerusalem was destroyed only because they disparaged the Torah scholars in it, as it is stated: “And they mocked the messengers of God and disdained His words and taunted His prophets, until the wrath of God arose against His people, until it could not be healed” (II Chronicles 36:16). What is the meaning of: Until it could not be healed? Rav Yehuda said that Rav said: It means that anyone who disparages Torah scholars cannot be healed from his wound.
