Time Travel in the Talmud

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 [interpretations of Jewish law]. 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.

Rabbi Yoḥanan said: All the days of the life of that righteous man, Ḥoni the Circle-Drawer, he was distressed over the meaning of this verse: “A song of Ascents: When the Lord brought back those who returned to Zion, we were like those who dream” (Psalms 126:1). He said to himself: Is there really a person who can sleep and dream for seventy years? How is it possible to compare the seventy-year exile in Babylonia to a dream? One day, he was walking along the road when he saw a certain man planting a carob tree. Ḥoni said to him: This tree, after how many years will it bear fruit? The man said to him: It will not produce fruit until seventy years have passed. Ḥoni said to him: Is it obvious to you that you will live seventy years, that you expect to benefit from this tree? He said to him: That man himself found a world full of carob trees. Just as my ancestors planted for me, I too am planting for my descendants. Ḥoni sat and ate bread. Sleep overcame him and he slept. A cliff formed around him, and he disappeared from sight and slept for seventy years. When he awoke, he saw a certain man gathering carobs from that tree. Ḥoni said to him: Are you the one who planted this tree? The man said to him: I am his son’s son. Ḥoni said to him: I can learn from this that I have slept for seventy years, and indeed he saw that his donkey had sired several herds during those many years. Ḥoni went home and said to the members of the household: Is the son of Ḥoni the Circle-Drawer alive? They said to him: His son is no longer with us, but his son’s son is alive. He said to them: I am Ḥoni the Circle-Drawer. They did not believe him. He went to the study hall, where he heard the Sages say about one scholar: His halakhot [interpretations of Jewish law] are as enlightening and as clear as in the years of Ḥoni the Circle-Drawer, for when Ḥoni would enter the study hall he would resolve for the Sages any difficulty they had. Ḥoni said to them: I am he, but they did not believe him and did not pay him proper respect. Ḥoni became very upset, prayed for mercy, and died. Rava said: This explains the folk saying that people say: Either friendship or death, as one who has no friends is better off dead.

But doesn’t Reish Lakish say: What is the meaning of that which is written: “This is the book of the generations of Adam, in the day that God created man” (Genesis 5:1)? Did Adam the first man have a book? Rather, the verse teaches that the Holy One, Blessed be He, showed Adam, the first man, every generation and its expositors, every generation and its Sages, and every generation and its leaders. When Adam arrived at the generation of Rabbi Akiva, he rejoiced in his Torah and was saddened by his death, as Rabbi Akiva was tortured and murdered. Adam said: “How weighty also are Your thoughts to me, O God! How great is the sum of them” (Psalms 139:17). It is evident from here that the Jews were destined to bear future generations from the beginning of time. And similarly, Rabbi Yosei says: The Messiah, son of David, will not come until all the souls of the body have been finished, i.e., until all souls that are destined to inhabit physical bodies will do so. As it is stated: “For I will not contend for ever, neither will I be always wroth; for the spirit that enwraps itself is from Me, and the souls that I have made” (Isaiah 57:16). According to Rabbi Yosei, in order for the Messiah to come in the end of days, it is necessary for the future generations to be born. The Gemara answers: Do not say that if our ancestors had not sinned we would not have come into the world, as we still would have been born; rather, it would have been as though we had not come into the world. We would have been of no importance, due to the previous generations that would have still been alive.
