Hearing the sounding of the shofar is the first commandment on Rosh Hashanah. One hundred notes are blown on the shofar in the synagogue on each day of Rosh Hashanah. The high-pitched blasts of the shofar make an urgent sound that remind all that hear it to reflect on the past year and the year to come. Jews believe that the blasts of the shofar revitalize the soul and intelligence of all Jews that listen to it's blasts during Rosh Hashanah. Throughout Rosh Hashanah no bitter or sour food is eaten.
People eat foods including a sweet bread called challah, pomegranates, and apples dipped in honey.
Sweet food is eaten throughout this holiday, symbolizing the desire to have a new year filled with sweetness. The people walk to flowing water, such as a creek or river, on the afternoon of the first day of Rosh Hashanah and empty their pockets or throw bread crumbs into the river, symbolically casting off their sins. This tradition has no reference in the Bible, but plays an important role in the celebration of Rosh Hashanah for many Jews. During Rosh Hashanah the people are encouraged to think only good thoughts and to be kind to all those around them. Happy new year .
