the Menorah
For Kwanzaa, kinara is the word for menorah.
The seven-branched Menorah of the Temple in Jerusalem dates back to the wanderings of the Children of Israel in the desert. The plans for this menorah are described in the Torah, Exodus 25:31-40. The text says that this, and all the other implements for the portable Tabernacle in the wilderness were made by the craftsman Betzalel. It was such a 7-branched menorah that was the subject of the "miracle of Hanukkah," when, during the rededication of the Temple, there was only enough oil for one day but it lasted for 8 days. Those 8 days explain why the menorah used to celebrate Hanukkah has 9 lamps or candles. Presumably, the first 9-branched menorah was made some time after the successful revolt in 166 BCE. We don't know exactly when.
