The Talmud discusses the dramatic events of Matan Torah — including the midrashic image of God holding the mountain over Israel 'like a barrel' — and describes the overwhelming, awesome nature of the revelation. This passage forms the conceptual backdrop for the night of Shavuot as a night of intense encounter with Torah.
״וַיִּתְיַצְּבוּ בְּתַחְתִּית הָהָר״, אָמַר רַב אַבְדִּימִי בַּר חָמָא בַּר חַסָּא: מְלַמֵּד שֶׁכָּפָה הַקָּדוֹשׁ בָּרוּךְ הוּא עֲלֵיהֶם אֶת הָהָר כְּגִיגִית, וְאָמַר לָהֶם: אִם אַתֶּם מְקַבְּלִים הַתּוֹרָה מוּטָב, וְאִם לָאו — שָׁם תְּהֵא קְבוּרַתְכֶם. אָמַר רַב אַחָא בַּר יַעֲקֹב: מִכָּאן מוֹדָעָא רַבָּה לְאוֹרָיְיתָא. אָמַר רָבָא: אַף עַל פִּי כֵן הֲדוּר קַבְּלוּהָ בִּימֵי אֲחַשְׁוֵרוֹשׁ, דִּכְתִיב: ״קִיְּמוּ וְקִבְּלוּ הַיְּהוּדִים״ — קִיְּימוּ מַה שֶּׁקִּיבְּלוּ כְּבָר. אָמַר חִזְקִיָּה, מַאי דִּכְתִיב: ״מִשָּׁמַיִם הִשְׁמַעְתָּ דִּין אֶרֶץ יָרְאָה וְשָׁקָטָה״, אִם יָרְאָה — לָמָּה שָׁקְטָה? וְאִם שָׁקְטָה — לָמָּה יָרְאָה? אֶלָּא בַּתְּחִילָּה יָרְאָה וּלְבַסּוֹף שָׁקְטָה. וְלָמָּה יָרְאָה? כִּדְרֵישׁ לָקִישׁ. דְּאָמַר רֵישׁ לָקִישׁ, מַאי דִּכְתִיב: ״וַיְהִי עֶרֶב וַיְהִי בֹקֶר יוֹם הַשִּׁשִּׁי״, ה׳ יְתֵירָה לָמָּה לִי? — מְלַמֵּד שֶׁהִתְנָה הַקָּדוֹשׁ בָּרוּךְ הוּא עִם מַעֲשֵׂה בְרֵאשִׁית וְאָמַר לָהֶם: אִם יִשְׂרָאֵל מְקַבְּלִים הַתּוֹרָה — אַתֶּם מִתְקַיְּימִין, וְאִם לָאו — אֲנִי מַחֲזִיר אֶתְכֶם לְתוֹהוּ וָבוֹהוּ.
The Gemara cites additional homiletic interpretations on the topic of the revelation at Sinai. The Torah says, “And Moses brought forth the people out of the camp to meet God; and they stood at the lowermost part of the mount” (Exodus 19:17). Rabbi Avdimi bar Ḥama bar Ḥasa said: the Jewish people actually stood beneath the mountain, and the verse teaches that the Holy One, Blessed be He, overturned the mountain above the Jews like a tub, and said to them: If you accept the Torah, excellent, and if not, there will be your burial. Rav Aḥa bar Ya’akov said: From here there is a substantial caveat to the obligation to fulfill the Torah. The Jewish people can claim that they were coerced into accepting the Torah, and it is therefore not binding. Rava said: Even so, they again accepted it willingly in the time of Ahasuerus, as it is written: “The Jews ordained, and took upon them, and upon their seed, and upon all such as joined themselves unto them” (Esther 9:27), and he taught: The Jews ordained what they had already taken upon themselves through coercion at Sinai. Ḥizkiya said: What is the meaning of that which is written: “You caused sentence to be heard from heaven; the earth feared, and was silent” (Psalms 76:9)? If it was afraid, why was it silent; and if it was silent, why was it afraid? Rather, the meaning is: At first, it was afraid, and in the end, it was silent. “You caused sentence to be heard from heaven” refers to the revelation at Sinai. And why was the earth afraid? It is in accordance with the statement of Reish Lakish, as Reish Lakish said: What is the meaning of that which is written: “And there was evening and there was morning, the sixth day” (Genesis 1:31)? Why do I require the superfluous letter heh, the definite article, which does not appear on any of the other days? It teaches that the Holy One, Blessed be He, established a condition with the act of Creation, and said to them: If Israel accepts the Torah on the sixth day of Sivan, you will exist; and if they do not accept it, I will return you to the primordial state of chaos and disorder. Therefore, the earth was afraid until the Torah was given to Israel, lest it be returned to a state of chaos. Once the Jewish people accepted the Torah, the earth was calmed.
