The Two Distinct Laws of Arba Kosos on Pesach Night

Full Summary

Rabbi Zweig presents a sophisticated analysis of the halachot of arba kosos (four cups of wine) on Pesach (פסח) night, based on Masechta Pesachim daf 108b. He begins by noting that both the Gemara (גמרא), Rashi (רש"י), and Tosafot learn that arba kosos is based on the four expressions of redemption (arba lashonot shel geulah): hotzeiti, hitzalti, ga'alti, v'lakachti. However, Rashi on daf 108a presents a different source - the three mentions of 'kos Pharaoh' in Pharaoh's cupbearer's dream plus the kos of birkat hamazon, creating four cups total. The Rambam (רמב"ם)'s formulation reveals two distinct halachot within arba kosos. First is the mitzvat aseh d'oraita to tell the story of the Exodus (sipur yetziat Mitzrayim), which Chachamim enacted should be performed over cups of wine (al hakos) for pirsumei nisa (publicizing the miracle). Second is the separate Torah (תורה) obligation of 'v'zacharta ki eved hayita' - remembering and celebrating as if one is personally leaving Egypt tonight, which requires actual drinking (chiyuv sh'tiya) in a manner befitting free people (derech cheirut). Rabbi Zweig explains that these two laws have different requirements. For sipur yetziat Mitzrayim, which is pirsumei nisa, one only needs the standard measure for kos shel bracha (m'lo lugmav), and others can fulfill their obligation by listening (shomea k'oneh). For the personal celebration of freedom, each individual must drink a full revi'it of strong wine (yayin she'eino mazug), ideally drinking the entire cup (kol hakos). This distinction resolves apparent contradictions in the Rambam. When discussing charity funds (tzedaka), one may only take money for pirsumei nisa purposes, not for personal mitzvot. Therefore, a poor person receives enough for the sipur requirement only - just enough for himself, since his family can be yotzei through shomea k'oneh. The celebration requirement must be fulfilled by each person individually when financially possible. Regarding women's obligations, the Rambam holds that women are exempt from sipur yetziat Mitzrayim (as it's not their traditional role as teachers), but are obligated in the personal celebration aspect due to 'af hein hayu b'oto ha'nes' (they too were part of the miracle). This explains why women don't appear in the Rambam's list of exceptional mitzvot aseh she'hazman grama that women must perform, yet are clearly obligated in arba kosos. The analysis also clarifies the dispute between Rashi and Tosafot regarding drinking all four cups at once. According to Rashi, if one drinks four cups simultaneously, they fulfill the 'yayin' requirement (the celebration) but not 'cheirut' (the storytelling structure). The Rambam agrees with Tosafot that simultaneous drinking fulfills neither requirement properly, as the celebration requires four distinct acts of drinking, and the storytelling requires the cups to accompany the narrative throughout the Seder.
