The term "aravah" refers to a type of willow tree, specifically the Salix species. It is commonly used in Jewish rituals, particularly during the festival of Sukkot. The aravah leaves are long and narrow, and they are typically gathered along with other plants, such as the lulav and hadassah, to create a special bundle for the holiday. During Sukkot, the aravah is waved in a ceremonial manner, symbolizing joy and the connection to nature. It is one of the four species, which also include the etrog (citron), and is an important part of the celebration, representing unity and gratitude.
