No, it's the Shield of David in Judaism.
Depends whom you ask.
Many have associated it with Primitive cults they don't "agree" with.
I cannot find any reference to the Star of David in the bible, here are some verses with the words in, which may or may not be helpful

The Seal of Solomon is depicted similarly.
The decision to adopt the shield of David in comparison to religious texts is fairly recent.
The hexagram is used in "magic" and has a history in Egypt, and with the druids in reference to a sun god I think. But I cannot find any text with reference to the Shield of David so cannot ascertain its goodness or evilness.
Superstition pulls you in the direction,
of your belief.
You've been watching too much tv.
