JERUSALEM—Jews the world over are preparing to celebrate Rosh Hashanukah or something this weekend, the traditional Jewish holiday marking some sort of rebirth and new beginning, or maybe the Jews' liberation from some foreign ruler 55,000 years ago. "Rash Kishansha is a very holy time for the Jewish people," said Paul Castellano, a guy from Houston whose gastroenterologist is Jewish. "I think Dr. Futterman said it's the holiday where they light that chandelier and blow that horn." Lasting 12 days, Ran Hosea is followed by Yor Kiplach, the Festival of Sand, during which no buttered bread may be eaten in remembrance of the flooding of the ancient Temple of Hosea.
