It’s a mitzvah to wave the lulav on each of the first seven days of Sukkot, as demonstrated Sept. 24 by Rabbi Shmuli Slonim of Rice’s Chabad Center. Beginning five days after Yom Kippur, Sukkot is named after the huts (“sukkot” in Hebrew) in which Jews are supposed to dwell during this weeklong celebration. (Photos by Jeff Fitlow)
