Why is the Star of David so called…did King David use it?
The Magen David (shield of David, or as it is more commonly known, the Star of David) is the symbol most commonly associated with Judaism today, but it is actually a relatively new Jewish symbol. It is supposed to represent the shape of King David’s shield (or perhaps the emblem on it), but there is really no support for that claim in any early rabbinic literature. In fact, the symbol is so rare in early Jewish literature and artwork that art dealers suspect forgery if they find the symbol in early works.
