The "star of david" did not come to symbolize the jewish people till after the time of Yeshua ...it was originally used on a flag, granted a jewish community to symbolize self rule, in gratitude for thier part of a military victory and came from the pagan symbol for luck.......it came to be known as the star of david as he was our most famous king/ruler and who we choose to identify with as a "man after G-ds own heart". This is the explanation given by an older rabbi, a wonderful man who truelly sought to honor HaShem in all he did and made jewish history his lifes passion.
