Avi Horowitz, an ultra-orthodox Jewish youth (L), dips a household utensils into a large vat of boiling water in Jerusalem before the start of the Passover holiday April 5, 2001. [Passover, which begins on the evening of April 7 with the "seder" dinner, is a weeklong holiday celebrating the exodus of the Hebrews from Egypt. It is a time when religious Jews thoroughly clean their homes and refrain from eating any food containing leavening such as bread. By dipping utensils in boiling water it rids them of any trace of leavening so that each piece will be clean for Passover. ]
