וְאַתָּ֗ה פֹּה֮ עֲמֹ֣ד עִמָּדִי֒ וַאֲדַבְּרָ֣ה אֵלֶ֗יךָ אֵ֧ת כָּל־הַמִּצְוָ֛ה וְהַחֻקִּ֥ים וְהַמִּשְׁפָּטִ֖ים אֲשֶׁ֣ר תְּלַמְּדֵ֑ם וְעָשׂ֣וּ בָאָ֔רֶץ אֲשֶׁ֧ר אָנֹכִ֛י נֹתֵ֥ן לָהֶ֖ם לְרִשְׁתָּֽהּ׃
여호와께서 너희가 내게 말할 때에 너희의 말하는 소리를 들으신지라 여호와께서 내게 이르시되 이 백성이 네게 말하는 그 말소리를 내가 들은즉 그 말이 다 옳도다
Ibn Ezra
But you stay here with Me implying that he then re-ascend the mountain, as it is written: and I will speak to you all the commandments, the decrees, and the judgments. Thus, most of the Torah was told to Moshe on Mount Sinai. However, Moshe apparently transmitted it during the entirety of their stay in the Sinai Desert, as well as during the eleven days’ trip from Sinai.
Ramban
THAT THEY MAY DO THEM IN THE LAND. I have explained it.199Above, 4:5.
Rashbam
'ואתה עמוד פה עמדי ואדברה אליך ...ועשו בארץ וגוthis is a reference to when Moses had said in 4,14 “G’d commanded me at that time to teach you to perform the commandments applicable in the Holy Land.”
