What is the origin of the Star of David?

According to Judeo/Christian tradition, the Star of David comes from both the actual shape of the symbol David chose to represent himself and his family, and also from an age-old 'Star' prophecy found in Numbers 24:17. First off, it is named "Star' simply because a hexagram looks very similar to the sun (or a star) which appears to have six spikes or points sticking out from its center when observed through hazy skies.

The Star of David is also named 'Star' due to the general consensus among believers that the ''Star' prophecy as written down in the Book of Numbers, was finally fulfilled by King David during his 40 year reign. Here is the relevant passage in the Book of Numbers-

I shall see him, but not now: I shall behold him, but not nigh: there shall come a Star out of Jacob, and a Sceptre shall rise out of Israel, and shall smite the corners of Moab, and destroy all the children of Sheth.

- Numbers 24:17

So, because it was David who chose the six-pointed hexagram as his Royal Emblem and because that symbol looked like a star as seen through hazy skies, the choice of the Word 'Star' seems quite appropriate. In addition, David's actions as the King of Israel resulted in the fulfillment of the 'Star' prophecy about a mighty ruler directly descended from Jacob who would unite the 12 tribes and finally establish the kingdom of Israel. This too shows the English phrase 'Star of David' to again be the perfect name for this symbol.
