Fire is a powerful symbol of sanctity in Jewish tradition. Fire marks the beginning and end of Shabbat with the lights of the Shabbat and Havdalah candles, setting the intervening 25 hours apart from all the other hours of the week. Fire is central during Chanukah, when for eight days, Jews commemorate the rededication of the Temple in Jerusalem by kindling the flames of the menorah and recalling the fire of the altar, ever-present and never to be extinguished. Fire can be used to purify objects, making that which is forbidden “kosher” or fit for ritual use. Under some circumstances, fire even takes an ordinary meal of grain or meat and turns it into an act of worship of God.
