Seder is the feast on the night of Passover. In ancient times, before the slavery in Egypt, Seder was celebrated as a spring festival. It was a time to come together at the beginning of harvest and to thank the Hebrew God for all that was provided.

Read the History of Passover here if you are curious. It’s a loosely based telling of the story of Exodus.

Another name for Passover is Pesach, pronounced PAY-sahch, with a "ch" as in the Scottich "loch". This name means in Hebrew, to pass through or pass over, to exempt or to spare. The celebration begins on the 15th day of the Jewish month Nissan (the Hebrew New Year month). The name is exemplary of the fact that God passed over the Hebrew households when he was slaying the firstborns of Egypt. The holiday is also referred to as: Chag he-Aviv (the Spring Festival), Chag ha-Matzoth (the Festival of Matzahs), and Z'man Cherutenu (the Time of Our Freedom). "Pesach" is also the name of the sacrificial lamb (an actual lamb) that was made in the temple on this holiday.
