Shulchan Menachem. Continuing from the sicha, the Rebbe explains that heseibah actually contains two distinct mitzvos.
First, there is a mitzvah in its own right—to lean as an expression of freedom on the night of Pesach. Second, there is a mitzvah as a condition within other mitzvos, specifically when eating matzah and drinking the four cups, that these actions must be performed while leaning.
When a person eats a k’zayis of matzah while leaning, he fulfills two things simultaneously: he performs the mitzvah of eating matzah properly, and he also fulfills the independent mitzvah of heseibah.
Within the independent mitzvah of leaning, there are also levels. The primary fulfillment is at the time of the mitzvos of matzah and the four cups. Beyond that, there is a mitzvah min hamuvchar to continue leaning throughout the meal, expressing a broader state of freedom.
With this understanding, the Rebbe explains the language of the Alter Rebbe’s Shulchan Aruch. First, the Alter Rebbe presents the general concept of leaning as a standalone idea. Then he addresses the specific requirement of leaning as it applies to matzah and the four cups.
This also explains why the Alter Rebbe brings the pesukim from Parshas Va’eira, which are the source for the four cups. Although there are multiple reasons given for the four cups, the Alter Rebbe emphasizes the verses of redemption, highlighting that the cups are directly connected to geulah. Since they express freedom, they must be performed in a manner of freedom—through leaning.
Furthermore, the Alter Rebbe adjusts the order of the pesukim from their original sequence. This is to correspond to the order in which the four cups are drunk at the Seder, emphasizing that not only do the four cups generally relate to redemption, but each individual cup corresponds to a specific stage of redemption.
Therefore, both the matzah and the wine are uniquely tied to cheirus, and for that reason, leaning is not merely an added detail—it is an essential condition for their proper fulfillment, while also remaining an independent mitzvah in its own right.
Summary
The Rebbe explains that heseibah has two aspects: an independent mitzvah of freedom and a condition within matzah and the four cups. This dual understanding clarifies the Alter Rebbe’s presentation and highlights the deep connection between these mitzvos and redemption.
