The fallen booth[1]
הרחמן הוא יקים לנו את סוכת דוד הנופלת[2]
May the Merciful One raise up for us the fallen[3] sukkah of King David[4]
Sukkos is a time for rejoicing. It’s one of the happiest festivals of the year. We cite Hallel. We encircle the bima with our Lulav and Esrog. We recite extra prayers. One such extra prayer is found at the end of Birkas HaMazon. In the prayer, we ask Hashem to restore the fallen sukkah of King David. This prayer is based off of a verse in Amos[5], which says that on that day, presumably when the Moshiach shall appear, Hashem will raise up the fallen sukkah of King David. I understand we mention this prayer this time of year because it says the word sukkah, but what is it referring to? What sukkah of King David was there, and how did it fall? What does it mean that we ask Hashem to raise it up again?
