Pesach: Kadesh and the Kos Rishon

AI summary (may contain mistakes)

Why is Kodesh at the Seder different from Kiddush on Shabbos? On Shabbos the mitzvah is the words, and the wine only lends them chashivus, so Chazal ask that a cheekful be drunk. At the Seder Chazal made drinking the four kosos the mitzvah itself, so the Shulchan Aruch, l'chatchila, has a full revi'is drunk from the first kos. Each kos is coupled with a mitzvah: Kiddush, Maggid, Birchas HaMazon and Hillel.

Key points

• On Shabbos the words are the Kiddush, but at the Seder Chazal made drinking the mitzvah.
• Reb Moshe Feinstein puts a revi'is at 4.42 fluid ounces, and the Rabbanan's shiur at 3.37.
• The halacha brought says leaning on nothing is no haseibah, and the leaning is to the left.
