רַ֧ק בַּאֲבֹתֶ֛יךָ חָשַׁ֥ק יְהוָ֖ה לְאַהֲבָ֣ה אוֹתָ֑ם וַיִּבְחַ֞ר בְּזַרְעָ֣ם אַחֲרֵיהֶ֗ם בָּכֶ֛ם מִכָּל־הָעַמִּ֖ים כַּיּ֥וֹם הַזֶּה׃
Только Господь наслаждался отцами твоими, чтобы любить их, и Он избрал их семя после них, даже у тебя, над всеми народами, как и сегодня.
Rashi
בכם [AND HE CHOSE …] YOU, even as you see yourselves the object of His pleasure מכל העמים, כיום הזה MORE THAN ALL OTHER PEOPLES THIS DAY.
Chizkuni
ויבחר בזרעם אחריהם, בכם, He chose their seeds after them, i.e. “whom did He choose” “you;” this is the meaning of the verse, as Rashi explains, based on the prefix ב in the word בכם. You, i.e. your generation, are the generation of the patriarchs’ seed that He has chosen. Rashi focuses on the words: כיום הזה, “as of now,” at the end of our verse.
Ibn Ezra
He has chosen their descendants who are you — and the phrase is followed by the appositive you .
