Ultra-Orthodox Jews watch others collecting spring water during the traditional Jewish rite of "Mayim Shelanu" in the Jerusalem mountains April 5, 2012. The water is used to prepare matza, traditional unleavened bread eaten during the upcoming Jewish holiday of Passover. Passover commemorates the flight of Jews from ancient Egypt, as described in the Exodus chapter of the Bible. REUTERS/Ronen Zvulun (JERUSALEM - Tags: SOCIETY RELIGION)
