With Star of Magen David pendant - the Star of David (Magen David in Hebrew or Mogen Dovid in Ashkenazi Hebrew, Shield of David, Solomon's Seal, or Seal of Solomon) is a generally recognized symbol of Judaism and Jewish identity. It is also known colloquially as the Jewish Star. Kabbalah makes use of this sign, arranging the Ten Sephiroth (sefirot, spheres) in it. With the establishment of the State of Israel the Jewish Star on the flag of Israel has also become a symbol of Israel.
Wearing a thin red string (as a type of talisman) is a custom associated with Judaism's Kabbalah in order to ward off misfortune brought about by an "evil eye" (עין הרע in Hebrew). In Yiddish the red string is called a roite bindele.
An ancient tradition teaches us that a red string, wound seven times around Rachel's Tomb, is endowed with mystical powers.
According to this tradition, by tying the string around his or her wrist, the wearer is protected from the destructive power of the Evil Eye, thus preventing disease, poverty, accidents or other misfortune from befalling the wearer.
