(9) Moses said to Joshua, “Pick some troops for us, and go out and do battle with Amalek. Tomorrow I will station myself on the top of the hill, with the rod of God in my hand.” (10) Joshua did as Moses told him and fought with Amalek, while Moses, Aaron, and Hur went up to the top of the hill. (11) Then, whenever Moses held up his hand, Israel prevailed; but whenever he let down his hand, Amalek prevailed. (12) But Moses’ hands grew heavy; so they took a stone and put it under him and he sat on it, while Aaron and Hur, one on each side, supported his hands; thus his hands remained steady until the sun set. (13) And Joshua overwhelmed the people of Amalek with the sword.

They went and they hid in a cave. A miracle occurred and a carob tree was created for them as well as a spring of water. They would remove their clothes and sit covered in sand up to their necks. They would study Torah all day in that manner. At the time of prayer, they would dress, cover themselves, and pray, and they would again remove their clothes afterward so that they would not become tattered. They sat in the cave for twelve years. Elijah the Prophet came and stood at the entrance to the cave and said: Who will inform bar Yoḥai that the emperor died and his decree has been abrogated? They emerged from the cave, and saw people who were plowing and sowing. Rabbi Shimon bar Yoḥai said: These people abandon eternal life of Torah study and engage in temporal life for their own sustenance. The Gemara relates that every place that Rabbi Shimon and his son Rabbi Elazar directed their eyes was immediately burned. A Divine Voice emerged and said to them: Did you emerge from the cave in order to destroy My world? Return to your cave. They again went and sat there for twelve months. They said: The judgment of the wicked in Gehenna lasts for twelve months. Surely their sin was atoned in that time. A Divine Voice emerged and said to them: Emerge from your cave. They emerged. Everywhere that Rabbi Elazar would strike, Rabbi Shimon would heal. Rabbi Shimon said to Rabbi Elazar: My son, you and I suffice for the entire world, as the two of us are engaged in the proper study of Torah. As the sun was setting on Shabbat eve, they saw an elderly man who was holding two bundles of myrtle branches and running at twilight. They said to him: Why do you have these? He said to them: In honor of Shabbat. They said to him: And let one suffice. He answered them: One is corresponding to: “Remember the Shabbat day, to keep it holy” (Exodus 20:8), and one is corresponding to: “Observe the Shabbat day, to keep it holy” (Deuteronomy 5:12). Rabbi Shimon said to his son: See how beloved the mitzvot are to Israel. Their minds were put at ease and they were no longer as upset that people were not engaged in Torah study.

I the Eternal am your God

R. Levi then offered them this explanation: It says, ’Did ever a people hear the voice of God?’ What does this mean? Had it said ‘The voice of God in His power’, the world would not have been able to survive, but it says instead: The voice of the Eternal is with power (Psalm 29:4) - that is, according to the power of each individual, according to the individual power of the young, the old, and the very small ones. God said to Israel: ‘Do not believe that there are many deities in heaven because you have heard many voices, but know that I alone am the Eternal your God,’ as it says, I am the Eternal your God (Deut. 5:6)
