Jubilees 1:1
1 During the first year of the Israelites' exodus from Egypt, in the third month — on the sixteenth of the month — the Lord said to Moses: “Come up to me on the mountain. I will give you the two stone tablets of the law and the commandments which I have written so that you may teach them.” 2 So Moses went up the mountain of the Lord. The glory of the Lord took up residence on Mt. Sinai, and a cloud covered it for six days. 3 When he summoned Moses into the cloud on the seventh day, he saw the glory of the Lord like a fire blazing on the summit of the mountain.
Berakhot 5a
Babylonian TalmudAnd Rabbi Levi bar Ḥama said that Rabbi Shimon ben Lakish said: God said to Moses, “Ascend to me on the mountain and be there, and I will give you the stone tablets and the Torah and the mitzva that I have written that you may teach them” (Exodus 24:12), meaning that God revealed to Moses not only the Written Torah, but all of Torah, as it would be transmitted through the generations. The “tablets” are the ten commandments that were written on the tablets of the Covenant, the “Torah” is the five books of Moses. The “mitzva” is the Mishna, which includes explanations for the mitzvot and how they are to be performed. “That I have written” refers to the Prophets and Writings, written with divine inspiration. “That you may teach them” refers to the Talmud, which explains the Mishna. These explanations are the foundation for the rulings of practical halakha. This verse teaches that all aspects of Torah were given to Moses from Sinai.
Notes and References
"... This formulation seemed to leave room for laws outside of the Torah, such as the additional stipulations found in the book of Jubilees itself. Tgat may be why Jubilees’ author chose to cite Exodus 24:12 here. This same biblical verse was used for a similar purpose, but still more expansively, in b. Berakhot 5a: “The ‘tablets’ refers to the Ten Commandments, ‘the Torah’ to Scripture [i.e. to the Pentateuch as a whole], ‘and the commandments’ to the Mishnah, ‘which I wrote’ to the Prophets and the Writings, ‘to teach them’ to the Gemara [i.e. oral teachings about the Mishnah, Torah, and other topics]—this verse [thus] teaches that all of these were given to Moses on Mount Sinai.” ..."
