Sukkot is a week-long Jewish festival that commemorates the Israelites' journey through the desert after the Exodus from Egypt, living in temporary shelters. It is celebrated by building and dwelling in a sukkah, a hut-like structure, and by waving the lulav and etrog, symbols of the harvest and unity. Sukkot is a joyful time that emphasizes gratitude, hospitality, and connection to nature and community.
