During the entire Sukkot holiday we are accustomed to say this prayer in the blessing after meals, based on the verse, “On that day I will establish the fallen sukka of David” (Amos 9:11). Why is this image chosen to represent the people of Israel?
Sukkot follows almost immediately after Yom Kippur and both share in the atmosphere of Tishrei – one of soul-searching, gazing at the year gone by, atonement, and looking towards the future. Still, as we know, these festivals are very different in essence, mood, and in the laws that characterize them.
Hallel is recited on numerous occasions: on holidays and Rosh Chodesh, during the sacrifice of a korban pesach (Pesachim 64a), during the wine libations of regular sacrifices (Arakhin 11a), and when Jerusalem or the Temple was expanded (Shavuot 14b). What is the source for Hallel, and can differences be drawn between its various forms?
