Rashi on Exodus 33:16/רש"י על שמות ל״ג:ט״ז

1ובמה יודע אפוא FOR WHEREIN SHALL IT BE KNOWN HERE [THAT I AND THY PEOPLE HAVE FOUND FAVOUR IN THY EYES] — i. e. wherein shall the “finding of favour” be known, הלא בלכתך עמנו IF NOT BY YOUR GOING WITH US!? And yet another thing do I ask You: that You should not let Your Shechinah rest upon the other peoples of the world (Berakhot 7a).

2ונפלינו אני ועמך SO SHALL WE BE DISTINGUISHED, I AND THY PEOPLE — through this very thing we shall become different from all the peoples. נפלינו is of the same root and meaning as in (Exodus 9:4) “And the Lord shall make a separation (והפלה) between the cattle of Israel etc.”
