ובאו עליך כל הברכות האלה והשיגוך. They will catch up with you although you did not even make an effort to “catch up” with them.

כי תשמע בקול ה' אלוקיך, all of this will occur when you make the pursuit of Torah your principal endeavour, relegating secular activities to something subordinate. In recognition of this approved lifestyle of yours, the blessings G’d bestows on you can obviously not be described as something that you were actively pursuing. The blessings mentioned by Moses here were the ones that were in evidence during the period of the first Temple during the part of that period when the Jewish people did observe the commandments of the Torah, until verse 9 יקימך ה' לו לעם קדוש, a condition which was fulfilled at the beginning of the period of the Second Temple as described by Shimon Hatzaddik in Yuma 21 who reported on the manifestation of miracles in the Second Temple as proof of the fulfillment of that prophecy by Moses.

וראו כל עמי הארץ, as our sages told us on folio 69 in Yuma about Alexander the Great prostrating himself in front of that High Priest.

והותירך ה' לטובה, meaning that your success will be demonstrably greater and more noticeable than that of other nations.

Moses concludes the blessings applicable to the period of the Second Temple by warning ולא תסור מכל הדברים אשר אנכי מצוה אתכם היום ימין או שמאל, meaning that the people are not to introduce changes in the commandments of the Torah, and especially not to make any changes in the social legislation, משפטים. Neither are they to introduce variations in the observance of certain commandments which were part of the culture of nations that lived in the land of Canaan, and which had been well entrenched in the entire region. Especially, is this forbidden if by adopting those habits, which, though unrelated to idolatry and of no religious significance, you adopt them in order thereby to display some respect for the culture of the members of those tribes still residing in your midst. In the Torah’s view this would constitute ללכת אחרי אלוהים אחרים לעבדם, that you are on the path to adopt idolatrous practices, eventually even worshipping those idols. However, the admonitions up unto verse 36 i.e. יולך ה' אותך ואת מלכך, refer to periods during the Second Temple, the period of the Seleucids until the Hasmoneans started their uprising to rid the land of the Neo Greeks. Eventually, Aristobulus, a King of the Hasmonean Dynasty, was exiled by the Romans to Rome at the command of Pompey. Starting with this incident up until verse 63 ונסחתם, Moses refers to the period of the destruction of the Second Temple by the Romans. What follows are admonitions dealing with our present exile.

אם לא תשמע בקול ה' אלוקיך לשמור לעשות את כל מצותיו וחקותיו אשר אנכי מצוך היום, with these words Moses introduces his admonitions, the ones which parallel chapter 26 in Leviticus, but are sounding far more devastating. Israel is described as “backsliding,” having, with the help of Torah legislation, been the frontrunner in civilised countries. Whenever the Torah speaks about the Jewish people abandoning the laws of the Torah, the intention is not to make us think that they slid into anarchy, but worse, they slid into adopting the laws of the prevalent cultures and civilisations. Clearly, this is an even greater affront to G’d the Lawgiver, than merely being passive and not carrying out Torah legislation. Social legislation involving tithes was largely ignored, leading to such great scholars as Hillel, and the High Priest Yochanan decreeing legalistic means of circumventing the legislation so that the people would not be guilty of violating such basic social laws as forgiving overdue debts at the end of the Sh’mittah year. The Rabbis, in a number of instances, were forced to preserve the spirit of the law, sometimes at the expense of what may be termed “the letter of the law.” The discontinuance of the examination by the priest of a woman suspected of marital infidelity, Sotah, is one such example, the Rabbis feeling that when infidelity had become the norm rather than the exception, it would not do to demand a miracle from G’d every time such a situation arose. Moreover, the chances were that the husband’s sexual life was not so free from blemish that he could point a finger at his wife. (Compare Shviit,1,3, Maasser Sheyni 5,15, Sotah 46,48,49) Other practices, such as referring disputes to pagan judges of the nation (Greeks or Romans) occupying Israel at the time, made it almost impossible for the Jewish judiciary, even when meaning to preside over Torah law, to be an effective legal instrument. All of these conditions became a self-fulfilling prophecy in the decline of the Jewish people as a holy nation and led to the destruction of Jerusalem and the end of Jewish independence on a land of their own.

והתמכרתם, you will begin to manufacture or make by hand all kinds of goods the host country lacks in order to secure your economic well being, but

ואין קונה, no one will buy these goods due to antisemitic reasons, as they do not want you to gain a foothold in their country.
