Rosh means head: Although considered the Jewish New Year, Rosh Hashanah does not mean “New Year” in Hebrew. The translation is actually “Head of the Year.” Just like your head (or more specifically, your brain) tells your body what to do, your actions and behavior on Rosh Hashanah have far-reaching consequences for the entire year.
Pass the pomegranate, not the pickles: Pomegranates, apples and honey are all foods that are symbolic to the holiday Rosh Hashanah. Every pomegranate is believed to contain 613 seeds. This number just happens to be identical to the number of mitzvot (commandments) in the Torah. So, eating a pomegranate can be a symbolic way to display the desire to fulfill the mitzvot.
