Hoshana Rabbah is the seventh day of the Jewish holiday of Sukkot, the 21st day of the month of Tishrei. This day is marked by a special synagogue service, the Hoshana Rabbah, in which seven circuits are made by the worshippers with their lulav and etrog, while the congregation recites Hoshanot. It is customary for the scrolls of the Torah to be removed from the ark during this procession. In a few communities a shofar is sounded after each circuit.

Hosanna is a liturgical word in Judaism and Christianity. In Judaism it refers to a cry expressing an appeal for divine help. In Christianity it is used as a cry of praise.
