Sforno on Deuteronomy 28:14/ספורנו על דברים כ״ח:י״ד

1Moses 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.
