Star of David

( Shield of David )
Moses Gaster claimed that the symbol was introduced into Judaism by Rabbi Akiba during the second century. Akiba allegedly used it as a Messianic symbol in the war of liberation conducted by Bar Kokhba, the Son of a Star, against the Emperor Hadrian.
This international sign was not accepted as a specifically Jewish symbol until Isaac Luria. He sees in it the image of the Adam Kadmon ( The primeval man in the world of the divine ten spheres or sefirot). The six triangles plus the hexagon in the center represents the seven lower spheres while the upper three are to be conceived as lying above it.
For the official use of the hexagram as the insignia of a Jewish community had its origin in Prague. Not knowing whether the Jews themselves chose the sign for their flag and seal or whether it was imposed on them by the Christian authorities.
The symbol has been preserved in a number of Hebrew manuscripts with letters similar to a Latin V which has three small circles at its three corners. It is said to have been constructed in the manner of a shield , for King David had a shield on which the Great Name of G-d containing seventy-two letters (a combination of holy names which according to an ancient Jewish legend made it possible for Israel's redemption) was engraved and which helped him to win all of his wars.
Not really knowing the real meaning of the symbol, one may say that, just at the time of its greatest dissemination, in the nineteenth century, the shield of David served as the empty symbol of a Judaism which itself was more and more falling into meaninglessness.
With the sanctity of a genuine symbol has been done by those who made it for million into a make of shame and degradation. Under this sign they were murdered; under this sign they came to Israel.
The sign which in our own days has been sanctified by suffering and dread has become worthy of illuminating the path into the abyss; there the symbol received its ultimate humiliation and there it won it's greatness.
