Menorah is a candelabrum with seven candles that is displayed in Jewish synagogues. The original design for the menorah is in the Torah, and it was used in rituals in the tabernacle (portable sanctuary) and later the Holy Temple in Jerusalem. Since the destruction of the Temple in Jerusalem, it has had no formal role in Jewish prayer services or rituals. The presence of a menorah in some synagogues is purely symbolic.
The one exception to this concerns the Jewish festivak of Chanukah, in which a nine branched version of the menorah is used; this nine branched menorah is properly called a Hanukiah.
The Hanukkah menorah includes eight candles, one for each day the Oil burned, plus the shammes, a "servant candle" that is used to light the others.
