The Haggadah (Hebrew: הגדה,
"telling") is a Jewish religious text that sets out
the order of the Passover Seder. Reading the Haggadah is a fulfillment
of the scriptural commandment to each Jew to "tell your son"
about the Jewish liberation from slavery in Egypt as described in
the Book of Exodus in the Torah. ("And thou shalt tell thy son
in that day, saying: It is because of that which the LORD did for
me when I came forth out of Egypt. " Ex. 13:8)
Sephardi and Oriental Jews also apply the term Haggadah to the service
itself, as it constitutes the act of "telling your son."
