Menorah

The menorah is described in the Bible as the seven-branched candelabrum made of gold and used in the portable sanctuary set up by Moses in the wilderness and later in the Temple in Jerusalem. Fresh olive oil of the purest quality was burned daily to light its lamps. The menorah has been a symbol of Judaism since ancient times and is the emblem on the coat of arms of the modern state of Israel. The menorah consisted of a base and a shaft with six branches, beaten out of solid gold. The six branches curved to the height of the central shaft so that all seven lamps at  their apexes were in a straight line. According to The Roman-Jewish historian Flavius Josephus states that three of the seven lamps were allowed to burn during the day also; however, according to the Talmud (Rashi, Tractate Shabbat 22b), only the center lamp was left burning all day, into which as much oil was put as into the others. Although all the other lights were extinguished, that light buried oil, in spite of the fact that it had been kindled first. The menorah symbolized the ideal of universal enlightenment. The seven branches allude to the branches of human knowledge, represented by the six lamps inclined inwards towards, and symbolically guided by, the light of God represented by the central lamp. The menorah also symbolizes the creation in seven days, with the center light representing the Sabbath. It is also said to symbolize the burning bush as seen by Moses on Mount Hareb.

In other cultures The kinara is also, like the menora, a seven-branch candleholder which is associated with the African American festival of Kwanzza. 

In Taoism, the Seven-Star Lamp qi xing deng 七星燈 is a seven-branched oil lamp lit to represent the 7 stars of the Northern Dipper.
