In anticipation of the upcoming festival of Purim, the lesson will be on the subject of hats in Jerusalem. The visitor to Jerusalem can't help wonder at the huge diversity of people of different nationalities and…at the different hats. A hat protects one from the sun, rain and cold, but, in Jerusalem, the hat is also a kind of an ID card worn on the head. The hat is a religious, cultural declaration that says something about the person under the hat, about his status and beliefs.
