Chumash: Acharei Mot, First Parsha with Rashi.
Tehillim: 97-103.

One Pesach, Reb Chayim Avraham (the Alter Rebbe's son) went to his brother (the Mitteler Rebbe) to wish him Gut Yom-Tov.
Reb Chayim Avraham related on that occasion that the Alter Rebbe had said, "On Pesach one does not offer a guest food and drink, but the guest may help himself. [1]
Notes:
Since many people have personal stringencies on Pesach they decline to eat outside their own homes. Offering food might prove awkward or embarrassing.
