Comentário sobre Deuteronômio 30:9

'והותירך ה, He will grant you success beyond any success you have ever enjoyed previously.

כי ישוב ה' לשוש עליך לטוב כאשר שש על אבותיך, “when Hashem will return and rejoice over you for good as He rejoiced over your forefathers.” It is possible that this verse alludes to the time when the King will return with His bride (the Jewish people), i.e. an allusion to the time of the redemption. At that time He will provide you with all the benefits accompanying such a return to favor. Should you inquire when exactly all this would happen, the Torah adds: “when you will hearken to the voice of the Lord your G’d to observe, etc.” The Jewish people are always expected to make the first move towards reconciliation with G’d, i.e. observing His commandments. Immediately G’d notices this, He in turn will hasten the rapprochement. Our fortunes depend on our becoming penitents. All this has been expressed in unmistakable language by Malachi 3,7: “שובו אלי ואשובה אליכם, “return to Me and I will return to you.” The letter ה at the end of the word אשובה in that verse is a reference to the final letter in the tetragrammaton, the attribute which created the universe.

כאשר שש על אבותיך, ”as He used to take delight in your forefathers.” This is a reference to the generation who inherited the Holy Land. G-d is addressing the exiles at this point.
