UviRashei Chadsheichem 5738 (Hemshech to Kimei Tziascha)Class One. Introduction: What is Mussaf? above Histalshelus. The mention of יציאת מצרים even after Moshiach some is due to some unique property of the initial Geula: the struggle! This will be special even then. Why Yidden ran away and won’t run when Moshiach comes.

UviRashei Chadsheichem 5738, Class Two. This class (beginning and end of the Ma’amar) explains Musaf Specifically there are two special יחודים on ראש חודש A. יחוד יעקב ורחל and B. יחוד ישראל ורחל but these two are similar (in השתלשלות) and above the two is יוסף whose יחוד is achieved by going into מצרים. The Rebbe explains that even one who is holding by יחוד ישראל ורחל still must have יחוד יעקב ורחל for reasons of אתכפיא being higher than אתהפכא. This then is יוסף the אתכפיא that follows אתהפכא and reveals the אין סוף that creates the יחודים altogether. This is why every ראש חודש is called ובראשי חדשיכם plural.
