Sometimes a symbol, and the meaning of that symbol, are the exact same thing. So too the Star of David and its unique visual picture of the 7 Days of Creation match each other with Mathematical precision. I’ll let the Rabbi explain:
“Still by exploring some various explanations on the meaning behind the Star of David, we can appreciate deep Jewish concepts. One idea is that a six-pointed star receives form and substance from its solid center. This inner core represents the spiritual dimension, surrounded by the six universal directions. (A similar idea applies to Shabbat the seventh day which gives balance and perspective to the six weekdays.)”
The faultless symmetry of 6, its relation to 3 and 2, and its regular division of the circle, are portrayed in the familiar hexagram known as the Shield of David. Seven, when represented as a compact group of circles reveals itself as a number of singular beauty and perfection, worthy of the important place accorded to it in all mystical philosophy.
The attacks being made on the Star of David…are often poorly veil ed attempts at Anti- Semitism. This can be seen in the false teaching that the Star of David is the Mark of the Beast because it has six points, six triangles, and six hexagon sides. However, the Hexagram shape of the Star of David is more properly viewed as…six triangles and one hexagon, which equals Seven shapes, not six!
The Hexagram, like the pentagram, was and is used in practices of the occult and is attributed to the 7 ‘old’ planets outlined in astrology.

Students of the Western Hermetic Tradition are no doubt familiar with the association of the six points and center of the Hexagram with the Seven Planets known to the ancients. (The word “planet” originally had a broader meaning than it is given today, and was used to refer to any celestial body observed to move in a regular cycle through the sky. According to this early usage, both the moon and the sun count as planets.)
