וַיְהִי֩ בַיּ֨וֹם הַשְּׁלִישִׁ֜י בִּֽהְיֹ֣ת הַבֹּ֗קֶר וַיְהִי֩ קֹלֹ֨ת וּבְרָקִ֜ים וְעָנָ֤ן כָּבֵד֙ עַל־הָהָ֔ר וְקֹ֥ל שֹׁפָ֖ר חָזָ֣ק מְאֹ֑ד וַיֶּחֱרַ֥ד כָּל־הָעָ֖ם אֲשֶׁ֥ר בַּֽמַּחֲנֶֽה׃
И было на третий день, когда было утро, на горе были громы и молнии, и густое облако, и голос рога громкий; и все люди, которые были в лагере, дрожали.
Midrash Tehillim
Another interpretation of “But his delight is in the Torah of God” (Psalms 1:2): This is what Scripture said, “Oh! Let all who are thirsty come for water, [and he who has no money, let him acquire [food] and eat it, and come and acquire without money, and without cost, wine and milk]” (Isaiah 55:1). Just as water comes from the heavens, as it is said, “When [God] bellows, there is a rumbling of water in the heavens” (Jeremiah 10:13); so too, words of Torah were given from the heavens, as it is said “You have seen for yourselves that I spoke with you from the heavens” (Exodus 20:19). Just as water is free to all, so too are words of Torah free for all, as it is said, “[let him who has no money] acquire [food] and eat it, and come and acquire without money, and without cost, wine and milk.” Just as water descends into the world with thunder and lightning, as it is said, “The voice of God is upon the waters” (Psalms 29:3), so too [regarding] words of Torah, “On the third day, as morning dawned, there was thunder, and lightning, [and a dense cloud upon the mountain, and a very loud blast of the horn; and all the people who were in the camp trembled]” (Exodus 19:16). Just as water [gives] life to all; so too, words of Torah [give] life to all, as it is said, “For they are [a source of] life to those who find them” (Proverbs 4:22). And it is written, “For this is not a trifling thing for you: [it is your very life]” (Deuteronomy 32:47). Just as water descends drop by drop only to form [great] rivers, so too [regarding] words of Torah. A person learns a single halakha one day, and a single halakha on the next day, until he becomes a flowing stream. Rabbi Oniya said, “What is water made for? To [water] gardens and orchards [irrespective of their quality]. Could it be that the same is true regarding words of Torah [that they enter the hearts of a person irrespective of their spiritual or ethical standing]? The verse states [otherwise, as it says,] “For the paths of God are upright; [the righteous can walk on them, while sinners stumble on them]” (Hosea 14:10). [As this teaching appears in Shir HaShirim Rabba 1:2:8, it says: “Rabbi Ḥanina of Caesarea said: Just as water is drawn to gardens, orchards, lavatories, and bathhouses, could it be that the same is true regarding words of Torah? The verse states [otherwise, as it says]: “For the ways of the Lord are upright; [the righteous can walk on them, while sinners stumble on them]” (Hosea 14:10).”] Rabbi [Yehuda Ha-Nassi] said, just as water covers the nakedness of the sea, so too words of Torah cover the nakedness of Israel, as it is said, “love covers up all faults” (Proverbs 10:12). Just as with water, an adult isn’t ashamed to ask a child to give him water to drink, so too with words of Torah, an adult isn’t embarrassed to ask a child to teach him a chapter or a halakha. Just as with water, if a person is thirsty for it, he won’t be too lazy to drink, so too with Torah, a student is not too lazy to go to his Rabbi to learn from him. There was a story of Rabbi Yossi who went to learn from his Rabbi, etc. [This is the Midrash alluding to a story that appears in Eruvin 47b – It teaches that a person, and even a priest, is allowed to leave the land of Israel in order to learn Torah from the teacher that is most suited to them. This Yossi (who is called Yosef in the Talmudic version of the story), was a priest based in Israel who travelled all the way to Tzidon, outside of Israel, to learn Torah from the teacher who was most suited to his style of learning, even though the greatest sage of that generation lived in Israel. Since the greatest sage didn’t suit Yossi’s style of learning, Yossi wasn’t too lazy to walk all the way to Tzidon, and to leave the holiness of the land of Israel]. Regarding that which is written “[Moses charged us with [observing] the Torah;] it is a heritage of the congregation of Jacob” (Deuteronomy 33:4): [it is a heritage] to all those that congregate with Jacob. [This entails that] even the convert that toils in the Torah is equal to a high priest, as it is said, “[You shall keep My laws and My rules,] which a person shall observe and live by them: [I am God]” (Leviticus 18:5). [The word “person,” in this context, is understood as applying to any human being, and thus:] Priests, Levites, and Israelites are not mentioned [in this context] but rather [any] person [including a convert]. See what is written, “The families of the scribes that dwelt at Jabez: [the Tirathites, the Shimeathites, the Sucathites; these are the Kenites who came from Hammath, father of the house of Rechab]” (I Chronicles 2:55). [The Talmud identifies these “Kenites” as the descendants of Jethro, the father-in-law of Moses, some of whom merited to sit as members of the Sanhedrin (Sotah 11a) – their status, as converts, did not get in the way of their becoming leading Torah sages]. And Shamaya and Avtalyion were descendants of Sisera [the Canaanite general], and they [nevertheless] taught Torah to the masses as members of the Great Assembly. Therefore it is written, “God spoke these words to your entire congregation” (Deuteronomy 5:19) [paying no heed to matters of status or pedigree].

14) Another interpretation: why did the Holy Blessed One give the Torah in the third month, rather than giving it when they were leaving Egypt? A parable to a king's son who was sick but stood from his sickness. His mother said to him, "Go study." The king said, "He has not healed from his sickness; he will wait two or three months and after that he will go study." Thus Israel, immediately upon leaving Egypt, were ready to receive the Torah, but were flawed from making bricks and mortar. The Holy Blessed One said, "Rest has still not come to My children from the enslavement, and how could they receive the Torah?" Thus He postponed them until the third month, and after that gave them the threefold Torah — alef, bet, gimel — by the hand of the threefold man. You can find all the works of the Torah are threefold! [The threefold Torah] (the Torah, prophets, and writings) with the threefold letters (alef, bet, gimel) by the hand of the threefold man — Moshe, his brother Aharon, and his sister Miriam were three, who came from the third tribe — Reuven, Shim'on, Levi (which is threefold in letters — lamed, vav, yod) — and bequeathed it to the threefold (priests, levites, and Israelites), children of threefold forefathers — Avraham, Yitsḥaq, and Ya'aqov — on the threefold day — as it is written, "On the third day" (Exodus 19:16) — and on the threefold month — as it is written, "On the third month that Israel left the land of Egypt." On the day that the Holy Blessed One rejoiced in Israel His people and Moshe His servant, Moshe celebrated in his heart, for he saw all that was with him. The land and those dwelling on it was shocked when they saw that Moshe son of 'Amram had taken the king's daughter and come down in great rejoicing, as it is said, "You ascended on high, took captives" (Psalms 68:19) The king's daughter is Torah, the gemstones are the twelve tribes.

I might think it was given at night; it is, therefore, written (Ibid. 19:16) "And it was on the third day, when it was morning, etc." I might think that it was given in silence; it is, therefore, written (Ibid.) "and there were thunders and lightnings." I might think that they did not hear the thunders; it is, therefore, written (Ibid. 20:15) "And all the people saw the thunders and the lightnings," and (Psalms 29:4) "the voice of the L–rd in majesty, etc."
