Mayim Shelanu

Haredi (Ultra-Orthodox) Jews are collecting water from a mountain spring outside Jerusalem.

The water will be used in the making of matzah, or unleavened bread, that is eaten instead of regular bread during the week-long Jewish holiday of Pesach (Passover), which commemorates the Jews' exodus from Egypt in Biblical times.

The water, once collected, will sit overnight, and be used the next day for the matzah baking. That water is called "Mayim Shelanu", water that has slept.
