Is there a flag for the Jewish religion?

There is no such thing as a Jewish flag.

The State of Israel has Israeli national symbols such as a flag that draw from Jewish inspirations. It is very similar to how there is no such thing as a Lutheran flag, but the cross on the Swedish flag is representative of how Lutheranism is the dominant religion in that country. The background of the Israeli flag is white with one blue stripe on top and one on the bottom then a blue Star of David in the centre.
