The Star of David is the primary modern emblem of the Jewish religion. How it came to be such is a matter of some debate. Legend has it that the emblem was used by the Biblical King David (hence the name Magen David, or “shield of David”). In reality, it was not associated specifically with the faith until the middle ages, when it began to appear on flags, tombstones, and synagogue decorations. It is probably not coincidental that the symbol was important to the flourishing kabbalistic tradition of the same time period. Kabbalistically, the hexagram symbolizes the six directions of space, the divine union of male and female energy, and the four elements. The Star of David is also important in the Rastafarian and Messianic Christian faiths.
