I did see that, but normally people that are into these kinds of things are very careful to distinguish "flags" from "coats of arms". But it's weird, isn't it, in this "age of universal knowledge through the Innerwebz", that when you go looking for the answer to such a seemingly simple question you just cannot find it.

And how would that thing even relate to Judaism? Is it the "Tiger of Judah"? Strange all the way around.
