What actually happened at Sinai?

(1) All Israel have a portion in the world to come, for it is written (Isaiah 60), “Thy people are all righteous; they shall inherit the land for ever, the branch of my planting, the work of my hands, that I may be glorified.” But the following have no portion therein: he who maintains that resurrection is not a biblical doctrine, the Torah was not divinely revealed, and an Epikoros.

"And they stood at the bottom of the mountain (Exodus 19:17)-" Rabbi Avdimi the son of Chama the son of Chasa said,"This teaches that the Holy One, Blessed be He, held the mountain over them like a barrel and said, 'If you accept the Torah, it is good. And if not, here shall be your graves.'" Rav Acha Bar Yaakov said,"From here there is a great claim against the Torah!" Rava said,"Even so, they accepted it again [willingly] in the days of Ahasuerus,as it is written,(Esther 9:27) 'They upheld and accepted' - they upheld what they already accepted." Hezkiah said, "Why is it written?"(Psalms 76:9) "From the heavens was heard judgement. The earth was frightened and quiet." If frightened, why quiet? If quiet, why frightened?Ratherin the beginning they were frightened and in the end they were quiet.And why were they frightened? According to Resh Lakish, it is written:(Genesis 1:31) "Then it was evening and it was morning of 'the' sixth day." 'The' is extra. Why do I have it?It teaches that G-d made a condition with the act of creation and said to it,"If Israel accepts the Torah, you will exist; if not, I will return you to chaos."

Rabbi Yoḥanan says in the name of Rabbi Bana’a: The Torah was given from the outset scroll by scroll, as it is stated: “Then I said, behold, I come with the scroll of the book that is written for me” (Psalms 40:8). King David is saying about himself that there is a section of the Torah, “the scroll of the book,” that alludes to him, i.e., “that is written for me.” This indicates that each portion of the Torah constitutes a separate scroll. Rabbi Shimon ben Lakish says: The Torah was given as a complete book, as it is stated: “Take this scroll of the Torah” (Deuteronomy 31:26), which teaches that from the outset the Torah was given as a complete unit.

In separate scrolls - When each portion was told to Moses, he wrote it down and, after 40 years when all the portions were completed, he attached them with sinews and bound them.

These are the laws, rules, and instructions that the LORD established, through Moses on Mount Sinai, between Himself and the Israelite people.

And Rabbi Levi Bar Chama said that Rabbi Shimon Ben Lakish said: Why does it say 'And I will give you the tablets of stone and the Torah and the Mitzvah that I have written to teach them.' (Exodus 24;12) The tablets- these are the ten utterances. Torah- this is the chumash. And the Mitzvah- this is the Mishna. That I have written- these are the Prophets and the Writings. To teach them--This is the Gemara This teaches you that all of them were given to Moses on Sinai.

Did Moshe learn the whole Torah? It is written about Torah: “It is longer than the land and wider than the sea” (Job 11), and within forty days Moshe learned it all?! Rather, the Holy One taught Moshe general principles.

Moshe received the Torah from Sinai and transmitted it to Yehoshua, and Yehoshua to the Elders, and the Elders to the Prophets, and the Prophets transmitted it to the Men of the Great Assembly. They said three things: Be deliberate in judgment, raise up many disciples and make a fence for the Torah.

§ Rav Yehuda says that Rav says: When Moses ascended on High, he found the Holy One, Blessed be He, sitting and tying crowns on the letters of the Torah. Moses said before God: Master of the Universe, who is preventing You from giving the Torah without these additions? God said to him: There is a man who is destined to be born after several generations, and Akiva ben Yosef is his name; he is destined to derive from each and every thorn of these crowns mounds upon mounds of halakhot. It is for his sake that the crowns must be added to the letters of the Torah. Moses said before God: Master of the Universe, show him to me. God said to him: Return behind you. Moses went and sat at the end of the eighth row in Rabbi Akiva’s study hall and did not understand what they were saying. Moses’ strength waned, as he thought his Torah knowledge was deficient. When Rabbi Akiva arrived at the discussion of one matter, his students said to him: My teacher, from where do you derive this? Rabbi Akiva said to them: It is a halakha transmitted to Moses from Sinai. When Moses heard this, his mind was put at ease, as this too was part of the Torah that he was to receive. Moses returned and came before the Holy One, Blessed be He, and said before Him: Master of the Universe, You have a man as great as this and yet You still choose to give the Torah through me. Why? God said to him: Be silent; this intention arose before Me. Moses said before God: Master of the Universe, You have shown me Rabbi Akiva’s Torah, now show me his reward. God said to him: Return to where you were. Moses went back and saw that they were weighing Rabbi Akiva’s flesh in a butcher shop [bemakkulin], as Rabbi Akiva was tortured to death by the Romans. Moses said before Him: Master of the Universe, this is Torah and this is its reward? God said to him: Be silent; this intention arose before Me.

§ Apropos the topic of verbal mistreatment, we learned in a mishna there (Kelim 5:10): If one cut an earthenware oven widthwise into segments, and placed sand between each and every segment, Rabbi Eliezer deems it ritually pure. Because of the sand, its legal status is not that of a complete vessel, and therefore it is not susceptible to ritual impurity. And the Rabbis deem it ritually impure, as it is functionally a complete oven. And this is known as the oven of akhnai. The Gemara asks: What is the relevance of akhnai, a snake, in this context? Rav Yehuda said that Shmuel said: It is characterized in that manner due to the fact that the Rabbis surrounded it with their statements like this snake, which often forms a coil when at rest, and deemed it impure. The Sages taught: On that day, when they discussed this matter, Rabbi Eliezer answered all possible answers in the world to support his opinion, but the Rabbis did not accept his explanations from him. After failing to convince the Rabbis logically, Rabbi Eliezer said to them: If the halakha is in accordance with my opinion, this carob tree will prove it. The carob tree was uprooted from its place one hundred cubits, and some say four hundred cubits. The Rabbis said to him: One does not cite halakhic proof from the carob tree. Rabbi Eliezer then said to them: If the halakha is in accordance with my opinion, the stream will prove it. The water in the stream turned backward and began flowing in the opposite direction. They said to him: One does not cite halakhic proof from a stream. Rabbi Eliezer then said to them: If the halakha is in accordance with my opinion, the walls of the study hall will prove it. The walls of the study hall leaned inward and began to fall. Rabbi Yehoshua scolded the walls and said to them: If Torah scholars are contending with each other in matters of halakha, what is the nature of your involvement in this dispute? The Gemara relates: The walls did not fall because of the deference due Rabbi Yehoshua, but they did not straighten because of the deference due Rabbi Eliezer, and they still remain leaning. Rabbi Eliezer then said to them: If the halakha is in accordance with my opinion, Heaven will prove it. A Divine Voice emerged from Heaven and said: Why are you differing with Rabbi Eliezer, as the halakha is in accordance with his opinion in every place that he expresses an opinion? Rabbi Yehoshua stood on his feet and said: It is written: “It is not in heaven” (Deuteronomy 30:12). The Gemara asks: What is the relevance of the phrase “It is not in heaven” in this context? Rabbi Yirmeya says: Since the Torah was already given at Mount Sinai, we do not regard a Divine Voice, as You already wrote at Mount Sinai, in the Torah: “After a majority to incline” (Exodus 23:2). Since the majority of Rabbis disagreed with Rabbi Eliezer’s opinion, the halakha is not ruled in accordance with his opinion. The Gemara relates: Years after, Rabbi Natan encountered Elijah the prophet and said to him: What did the Holy One, Blessed be He, do at that time, when Rabbi Yehoshua issued his declaration? Elijah said to him: The Holy One, Blessed be He, smiled and said: My children have triumphed over Me; My children have triumphed over Me.
