Comentário sobre Deuteronômio 11:27

את הברכה [I SET BEFORE YOU] THE BLESSING — with the condition that you should obey (אשר תשמעו‎).

את הברכה אשר תשמעון, "The blessing if you will hearken, etc." The word את which frequently means "with" means here that in addition to the blessing which is the result of walking in G'd's paths there would be a bonus, i.e. they would hearken to G'd's commandments. Hearkening to G'd's commandments is perceived as a pleasurable experience by itself. It helps the soul to feel "alive" as we know from Isaiah 55,4: שמעו ותהי נפשכם, "hearken and your souls will come alive." Whenever someone who studies Torah gains an understanding of what the Torah has in mind he experiences a physical and spiritual sense of wellbeing. He owes G'd a debt of gratitude for affording him such pleasure. There is no need to add that such a person cannot demand a reward from G'd for having allowed him to experience such joy.

את הברכה, which would be on Mount Gerizim on condition that 'אשר תשמעו אל מצות ה', וגו, that you will listen, etc.
