Class One. A Possuk without RaShI or the Gemara reads quite differently. We blow when all is new and from Pleasure (Shofar). But it comes down from there into Bachodesh HaShvii, Biechad Lachodesh and Yom (Zichron) Truah.
Class Two. Two becomes three (Perhaps: Pshitus, Klal, Pratim): Tiku Bachodesh: the source of newness that encompasses all. Bachodesh HaShvii includes 1) Seventh, 2) Full, 3) Empowerment. The three details: 1) BiEchad Lachodesh, 2) Mikra Kodesh and 3) Yom (Zichron) Truah.
Class Three. Continued. In truth Avodah is in Elul, once Rosh Hashana comes, it is really up to Him. What this means in Avodah.
