וְלָקַחְתִּ֨י אֶתְכֶ֥ם לִי֙ לְעָ֔ם וְהָיִ֥יתִי לָכֶ֖ם לֵֽאלֹהִ֑ים וִֽידַעְתֶּ֗ם כִּ֣י אֲנִ֤י יְהוָה֙ אֱלֹ֣הֵיכֶ֔ם הַמּוֹצִ֣יא אֶתְכֶ֔ם מִתַּ֖חַת סִבְל֥וֹת מִצְרָֽיִם׃
Aku akan mengambil kamu menjadi umat-Ku, dan Aku akan menjadi Allahmu; dan kamu akan mengetahui bahwa Akulah Yang Mahakekal, Allahmu, yang membawa kamu keluar dari bawah beban kerja paksa orang Mesir.
Ramban
AND I WILL TAKE YOU TO ME FOR A PEOPLE. That is, when you will come to Mount Sinai and you will accept the Torah. There, [at Mount Sinai], it was said, Then ye shall be Mine own treasure.41Further, 19:5.
Sforno
ולקחתי אתכם לי לעם, this will occur at the revelation at Mount Sinai.
