Sterling Silver w Opalit David Shield Necklace. Pendant Measurements 0.65" X 0.65". Sterling Silver Pendant and Necklace. The Star of David or Shield of David or Magen David is a generally recognized symbol of Jewish identity and Judaism and Zionism. It is named after King David of ancient Israel. The term refers directly to God, who shielded the Biblical David in battle and during his flight from Saul. According to the Kabbalah, the Star of David symbolizes the six directions of space plus the center, under the influence of the description of space found in the Sefer Yetsira (TheBook of the Creation): Up, Down, East, West, South, North, and Center. Naomi Jewelry is proud to have this Star of David necklace in stock.
