From my grandfather's talks of Elul 5635 (1875): The three days before Shabbat are a preparation for Shabbat. The Zohar says1 about Shabbat that "from it are all days blessed."2 "All days" refers to the six days of the week on which G‑d conferred a general blessing - "G‑d will bless you in all you do." The blessing of Shabbat is for the days preceding it and the days following it. The preparations for Shabbat begin Wednesday, and are announced by the brief l'chu n'ran'na3 of three verses.
