My revered father once said: “Today is Shabbos HaGadol,1 and concerning Shabbos it is written, ‘You shall call Shabbos a delight.’2 The difference between Shabbos and Yom-Tov is that concerning Yom-Tov we say ‘festivals for joy (simchah),’ whereas Shabbos is called ‘a delight’ (oneg). The phrase Shabbos HaGadol thus implies ‘a great delight.’ I visited my grandfather3 at the heichal.4 He’s preparing himself for the hillula.”5
