The Menorah is a seven-branch candelabra which has symbolized Judaism for nearly 3000 years.  Originally found in the ancient Holy Temple of Jerusalem, a new branch was lit each day of the week. Some say the fully lit Menorah represented the burning bush as seen by Moses.  Modern Menorahs, however, have nine branches to symbolize the miracle of Hanukkah, when the flame burned for eight days even though there was only enough oil for fewer days.  The ninth branch, the shamash, is used to light the other candles.
