אֶֽת־הַבְּרָכָ֑ה אֲשֶׁ֣ר תִּשְׁמְע֗וּ אֶל־מִצְוֺת֙ יְהוָ֣ה אֱלֹֽהֵיכֶ֔ם אֲשֶׁ֧ר אָנֹכִ֛י מְצַוֶּ֥ה אֶתְכֶ֖ם הַיּֽוֹם׃
너희가 만일 내가 오늘날 너희에게 명하는 너희 하나님 여호와의 명령을 들으면 복이 될 것이요
Rashi
את הברכה [I SET BEFORE YOU] THE BLESSING — with the condition that you should obey (אשר תשמעו).
Ibn Ezra
The blessing, that you will observe I.e., through your observing, you become blessed. A blessing is an increase in good, whereas a curse [Hebrew: qәlalah] is a reduction (from “degrade” [Hebrew: qalah]).
Rashbam
את הברכה, which would be on Mount Gerizim on condition that 'אשר תשמעו אל מצות ה', וגו, that you will listen, etc.
