Ultra-Orthodox Jews take part in the "Mayim Shelanu" ceremony to collect water from a natural spring, near Jerusalem April 21, 2016. The water is used to make matza, the traditional unleavened bread to be eaten on the Jewish holiday of Passover which starts on Friday. Passover commemorates the flight of Jews from ancient Egypt, as described in the Exodus chapter of the Bible. REUTERS/Ronen Zvulun
