A major Jewish holiday commemorating the freedom of the Israelites from slavery in Egypt under the leadership of Moses, who was directed by God. The account is found in Exodus, the second book of the Hebrew Scriptures and the Christian Old Testament. Passover takes its name from God’s instruction to the Israelites to mark the upper part of their homes’ doors with lamb’s blood so the Angel of Death would “pass over” their homes as he killed the firstborn male of each family in Egypt during the 10th plague. Passover, also called by its Hebrew name Pesach (pronounced “PAY-sakh”), is celebrated in late March or early April and lasts for seven days in Israel, though most outside of Israel celebrate for eight days. On the first two nights of Passover, it is traditional for a Jewish family to gather for a special dinner called a seder in which the story of the Exodus is retold. See seder and Jewish holidays.
