The blessing after the reading of haftarah always sanctifies the day on which it is read. Throughout most of the year, that day is Shabbat, but haftarah is also read on the High Holidays.
It is a mitzvah to celebrate in the sukkah. While the Torah instructs us to live in the sukkah for seven days, many choose to only eat meals in the sukkah. When eating or reciting kiddush in the sukkah, recite this blessing:
As we gather this Shabbat, each in our own communities, we are united by the grief and anguish we feel over the destruction of homes and lives by fire this week.
On Shabbat, holidays and at certain other festive meals, begin Birkat HaMazon (grace after meals) with "A Pilgrim's Song."
