In the third aliyah Moshe admonishes the Jewish people to observe all of G-d's commandments and walk in His ways because G-d has set us apart as a treasured people. This aliyah begins with the words: Hayom hazeh -- This day your G-d commanded you... Rashi says this means that every day we should view the commandments as though we were commanded that very day. And the words V'shamarto v'osiso osom -- you shall therefore observe and do them... Rashi says that this alludes to a divine voice that blesses the farmer: "you have brought first-fruits today, you will be found worthy to bring them again next year."
