On the Israel Science and Technology Homepage I found an interesting interpretation of the Star of David as a symbol for the Ingathering of the Israelites. Dr. Semion Natliashvili created a drawing of Jews standing in the shape of a Star of David and reading from the Bible. Beneath them there are Hebrew words from Isaiah 60:4:
"Lift up your eyes round about and see; they all gather together, they come to you. Your sons will come from afar..."
The author of this web page added:
"The Star of David symbolizes the gathering of the Jewish People from all corners of the world including Georgia (country of birth of the artist)"...
I like this interpretation. One can look at the Star of David from the center to the corners and have associations of development and expansion, but one can also look at it the other way round, from the corners to the center – and then the above mentioned interpretation shows itself naturally.
