The menorah, a 7-branched candelabrum used in the Temple, is one of the oldest symbols of Judaism. Originally the menorah in the Sanctuary was lit every evening and cleaned it out every morning, the wicks were replaced and fresh olive oil was poured into the cups. The instructions for design of the menorah are given in Exodus 25:31-40.

The menorah is a symbol of the nation of Israel's mission to be "a light unto the nations." (Isaiah 42:6). Learned men believe that light is not a violent force; Israel will accomplish its mission by setting an example, not by using force. According to the Torah, when a man named Zechariah saw a menorah, and G-d explained: "Not by might, nor by power, but by My spirit." (Zechariah 4:1-6)

In synagogues, the ner tamid, the eternal life, symbolizes the menorah.

A menorah used for Chanukah is different than the menorah in the synagogue. A 9-branched menorah is used on Chanukah because this holiday celebrates the miracle of one day's worth of oil for a menorah lasting for eight days.
