וּבַמֶּ֣ה ׀ יִוָּדַ֣ע אֵפ֗וֹא כִּֽי־מָצָ֨אתִי חֵ֤ן בְּעֵינֶ֙יךָ֙ אֲנִ֣י וְעַמֶּ֔ךָ הֲל֖וֹא בְּלֶכְתְּךָ֣ עִמָּ֑נוּ וְנִפְלֵ֙ינוּ֙ אֲנִ֣י וְעַמְּךָ֔ מִכָּ֨ל־הָעָ֔ם אֲשֶׁ֖ר עַל־פְּנֵ֥י הָאֲדָמָֽה׃ (פ)
װאָרום מיט װאָס דען זאָל דערקענט װערן, אַז איך האָב געפֿונען לײַטזעליקײט אין דײַנע אױגן, איך און דײַן פֿאָלק, אױב ניט דורך דײַן גײן מיט אונדז, אַז מיר זאָלן זײַן אױסגעצײכנט, איך און דײַן פֿאָלק, פֿון אַלעם פֿאָלק װאָס אױפֿן געזיכט פֿון דער ערד?

ובמה 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).
Ramban
V’NIPHLINU’ (SO THAT WE BE DISTINGUISHED) I AND THY PEOPLE. This means that our portion be that which is unique, something which is not to be found amongst all the people that are upon the face of the earth.
Sforno
ובמה יודע איפא, even though we may indeed enter the Holy Land and the angel will drive out the Canaanites, how would anyone become aware that what was happening was orchestrated by Divine forces? After all, people get driven out from their land in war all the time! There is nothing supernatural in such a phenomenon.

ונפלינו 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.”
