It is taught in a baraita (Tosefta 4:5): Rabbi Yosei says: Ezra was suitable, given his greatness, for the Torah to be given by him to the Jewish people, had Moses not come first and received the Torah already. With regard to Moses the verse states: “And Moses went up to God” (Exodus 19:3), and with regard to Ezra the verse states: “This Ezra went up from Babylon and he was a ready scribe in the Torah of Moses, which the Lord, the God of Israel, had given” (Ezra 7:6). Just as the going up stated here, with regard to Moses, is for the Torah, which he received from God and transmitted to the Jewish people, so too, the going up stated there, with regard to Ezra, is for the Torah, as he taught Torah to the Jewish people and was suitable to have originally merited to give it.
Matan Torah 1
(ג) וַיָּבֹ֣א מֹשֶׁ֗ה וַיְסַפֵּ֤ר לָעָם֙ אֵ֚ת כָּל־דִּבְרֵ֣י יְהוָ֔ה וְאֵ֖ת כָּל־הַמִּשְׁפָּטִ֑ים וַיַּ֨עַן כָּל־הָעָ֜ם ק֤וֹל אֶחָד֙ וַיֹּ֣אמְר֔וּ כָּל־הַדְּבָרִ֛ים אֲשֶׁר־דִּבֶּ֥ר יְהוָ֖ה נַעֲשֶֽׂה׃
(3) And Moses came and told the people all the words of the LORD, and all the ordinances; and all the people answered with one voice, and said: ‘All the words which the Lord hath spoken will we do.’
Matan Torah 2/Hakhel 1
Why Matan Torah 2?
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.
(יז) ויתיצבו בתחתית ההר. מלמד שכפה עליהן הר כגיגית (שבת פח, א), פירוש שהראה להם כבוד ה' בהקיץ ובתגלות נפלאה עד כי ממש בטלה בחירתם הטבעי ויצאה נשמתם מהשגת כבוד ה', והיו מוכרחים כמלאכים בלא הבדל, וראו כי כל הנבראים תלוי רק בקבלת התורה
Meshech Chachma Exodus 19:14
“And they stood at the foot of the mountain” – this teaches that God held the mountain above them like a barrel. This means, that He showed them the glory of God in revealed and wondrous ways, up to the point where their natural free choice was literally removed, and their souls departed from exposure to the glory of God. They were forced, like angels, without the ability to discern, as they saw with complete clarity that all of creation is dependant on the Torah.
Constant Revelation
(כא) פסקא יב אות כא (כא) ביום הזה באו מדבר סיני (שמות יט א) וכי ביום הזה באו אלא כשתהא למד דברי לא יהו בעיניך ישנים אלא כאילו היום ניתנה תורה ביום ההוא אין כת' כן אלא ביום הזה
“On this day they came to Sinai” — Did they come today? But rather, it
means that when you study the words of Torah, do not let them be old in your sight, but as if I gave them today.
(כב) בֶּן בַּג בַּג אוֹמֵר, הֲפֹךְ בָּהּ וַהֲפֹךְ בָּהּ, דְּכֹלָּא בָהּ. וּבָהּ תֶּחֱזֵי, וְסִיב וּבְלֵה בָהּ, וּמִנַּהּ לֹא תָזוּעַ, שֶׁאֵין לְךָ מִדָּה טוֹבָה הֵימֶנָּה:
(22) Ben Bag Bag says: Search in it and search in it, since everything is in it. And in it should you look, and grow old and be worn in it; and from it do not move, since there is no characteristic greater than it.
The rabbi of Kotzk was asked: “Why is Shavuot called ‘the time the Torah was given’ rather than the time we received the Torah?” He answered: “The giving took place on one day, but the receiving takes
place at all times.”
