Chasidut sur Le Deutéronome 27:12

אֵ֠לֶּה יַֽעַמְד֞וּ לְבָרֵ֤ךְ אֶת־הָעָם֙ עַל־הַ֣ר גְּרִזִ֔ים בְּעָבְרְכֶ֖ם אֶת־הַיַּרְדֵּ֑ן שִׁמְעוֹן֙ וְלֵוִ֣י וִֽיהוּדָ֔ה וְיִשָּׂשכָ֖ר וְיוֹסֵ֥ף וּבִנְיָמִֽן׃

"Voici quelles tribus prendront position sur le mont Garizim, pour la bénédiction à donner au peuple, quand vous aurez passé le Jourdain: Siméon, Lévi et Juda; Issachar, Joseph et Benjamin.

Another way of explaining the word ‎היום‎ in our verse is that ‎although the “blessings” and “curses” which will in due course, be ‎pronounced inside the Holy Land at Mount Gerizim and Mount ‎Eyvol, (Deuteronomy 27,12-26) the “blessing of which Moses ‎speaks here applies immediately, and the people do not have to ‎wait until they have conquered part or all of the land of Canaan. ‎Moses spells out the blessing with the words: ‎אשר תשמעו‎, in order ‎for us to understand that the very fact that we hearken to G’d’s ‎instructions brings blessings in its wake. Merely listening to how ‎to perform a commandment is by itself the performance of a ‎commandment.‎‎
