Keil & Delitzsch

An office-bearer of the kind described is now introduced per mimesin as speaking. "Come here, I will fetch wine, and let us drink meth; and tomorrow shall be like today, great, excessively abundant." He gives a banquet, and promises the guests that the revelry shall be as great tomorrow as today, or rather much more glorious. מחר יום is the day of tomorrow, τὸ ἐπαύριον, for mâchâr is always without an article; hence et fiet uti hic (dies) dies crastinus, viz., magnus supra modum valde. יתר, or יתר (as it is to be pointed here according to Kimchi, Michlol 167b, and Wrterbuch), signifies superabundance; it is used here adverbially in the sense of extra-ordinarily, beyond all bounds (differing therefore from יותר, "more," or "singularly," in the book of Ecclesiastes).
