Greco-Roman Period This passage shows how the Rabbis understood both halakhah and aggadah to be part of the oral Torah, given by God at Sinai.

Even that which an experienced student will teach, has already been taught to Moses at Sinai.” 127 126. Trans. S. Berrin. 127. Deut. 9-10, describing the writing on the tablets of the Ten Commandments, says, “And on them was written according to all the words which the Lord spoke with you on the mountain.” Rabbi Joshua noted that it does not simply say “Upon them” but “And upon them”; not simply “all” but “according to all”; not simply “words” but “the words.” He says that these apparently superfluous words were added to teach that the revelation at Sinai included much more than the Ten Commandments themselves, namely, Scripture, Mishnah, etc.
