The Jewish alphabet always begins on the right thumb. Looking from underneath, clockwise from top left, my right thumb, right index finger, and left index finger.   The first letter can be interpreted as a fan, thus representing air.   The second letter can represent the earth, because it's the first letter of the Torah (Genesis), starts the story of creation, or is sometimes considered a redirected river in a different font.   The bottom letter, the seventh, could be yearning, trying to find the stars Moses named as 'signs and seasons,' or additional symbolisms.   The seventh letter is shown backwards on Orion's belt.   The total of these three letters aleph, bet, and zion equals ten for the commandments on the tablets.
