Passover, or Pesach, is a Jewish festival that celebrates the Exodus from Egypt. It lasts a week, from the "15th day of Nisan" to the "22nd day of Nisan" (21st in Israel and liberal diaspora Jews).
History[]
More than 3,000 years ago, God aided the Children of Israel in their escape from slavery by inflicting ten plagues upon ancient Egypt. The last of these saw a spirit of the Lord slay every first-born in Egypt, but "pass over" Jewish homes marked with the blood of a slaughtered lamb. The festival celebrates the return of freedom to the enslaved Jewish people.
