וַיֹּ֗אמֶר הִנֵּ֣ה אָנֹכִי֮ כֹּרֵ֣ת בְּרִית֒ נֶ֤גֶד כָּֽל־עַמְּךָ֙ אֶעֱשֶׂ֣ה נִפְלָאֹ֔ת אֲשֶׁ֛ר לֹֽא־נִבְרְא֥וּ בְכָל־הָאָ֖רֶץ וּבְכָל־הַגּוֹיִ֑ם וְרָאָ֣ה כָל־הָ֠עָם אֲשֶׁר־אַתָּ֨ה בְקִרְבּ֜וֹ אֶת־מַעֲשֵׂ֤ה יְהוָה֙ כִּֽי־נוֹרָ֣א ה֔וּא אֲשֶׁ֥ר אֲנִ֖י עֹשֶׂ֥ה עִמָּֽךְ׃
Então disse o SENHOR: Eis que eu faço um pacto; farei diante de todo o teu povo maravilhas quais nunca foram feitas em toda a terra, nem dentro de nação alguma; e todo este povo, no meio do qual estás, verá a obra do SENHOR; porque coisa terrível é o que faço contigo.
Rashi on Exodus
כרת ברית [BEHOLD, I] MAKE A COVENANT about this.
Sforno on Exodus
הנה אנכי כורת ברית, to be in your midst. Compare Megillah 29 “when the Jewish people were exiled to Babylonia the presence of the Lord was “exiled” together with them, i.e. accompanied them; when they were exiled to Eylam the same was true. Even when they were exiled to Edom (by the Romans) this remained true.
Rashbam on Exodus
הנה אנכי כורת ברית, with regard to your request that I personally go with you, the answer is positive, as well as with regard to your request to grant you and the people a mark of distinction. (33,16) נגד כל העם אעשה לך, I will perform such miracles וראה כל העם and the whole nation will see the greatness כי נורה הוא, that it is indeed awesome; we know this from verse 30 where we read that the people were afraid of coming near Moses. It is also reported in verse 35 that the face of Moses radiated rays of light.
