Yesterday was the first day of the Jewish holiday of Passover(beginning at sundown). It was especially poignant this year as yesterday was the anniversary of the 1943 uprising of the Warsaw Ghetto against the Nazis. The Passover, of course, commemorates the Exodus from Egypt, and it begins according to the Hebrew (and Samaritan) lunar calender on the 15th of the month of Nisan, the first month in that calender. The term refers to the Biblical "passing over" of the Angel of Death from the houses of the Jews who had smeared the blood of the Pascal Lamb on their doorways. In Israel Passover is a seven day holiday, but in the diaspora the length of the festival is typically eight days. amongst the orthodox.
Fuller accounts of Passover, its traditions,its history and its significance can be found on a Wikipedia site on same and also at Chabad.org .
So... from Molly to her Jewish readers, may you have a joyous Passover, and may you and yours be happy and prosperous in the year to come.
