Passover

• 1. Origins And Evolution

  ›

  Modern scholars trace the roots of Passover to ancient apotropaic rituals that predate the biblical Exodus narrative. These early rites were designed to protect family homes from demonic forces using the blood of a slaughtered sheep daubed on doorframes with hyssop. The ritual existed within clan boundaries before evolving into a national festival. Some theories suggest this practice merged with Canaanite agricultural festivals celebrating the spring barley harvest and unleavened bread. This merger created the double origin hypothesis where an old protective rite combined with a new historical memory. Scholars John Van Seters, Judah Segal, and Tamara Prošić challenge the idea that these two distinct traditions simply fused together. They argue for more complex interactions between semi-nomadic pre-Israelite rituals and later cultic traditions. The name Passover itself remains debated among linguists who study cognate languages like Akkadian or Egyptian. One translation suggests the verb means to have pity while another implies passing over houses during the tenth plague.

  ›

  The Book of Exodus commands Moses to tell the Israelites to slaughter a lamb and mark their doorframes with its blood. God promised to send the Angel of Death to smite all firstborn in Egypt but would pass over homes marked with blood. Pharaoh refused God's demand to let the people go until after the tenth plague forced him to permit their departure. Biblical regulations require all leavening be disposed of before the 15th day of Nisan according to Exodus 13:7. An unblemished lamb known as the Paschal Lamb was set apart on the 10th of Nisan and slaughtered at dusk when the 14th ended. This sacrifice had to be eaten roasted without removing internal organs alongside unleavened bread called matzah and bitter herbs. Nothing of the sacrifice could remain until morning of the 15th of Nisan and had to be burned instead. The biblical requirements for slaying lambs in individual homes were celebrated in Egypt but changed once the Tabernacle operated. Passover lambs were then sacrificed only at the door of the Tabernacle rather than in Jewish homes. King Josiah restored the celebration of Passover to a standard not seen since the days of the prophet Samuel. Ezra recorded the celebration by Jews who returned from exile in Babylon after the temple was rebuilt.

• 3. Calendar And Timing

  ›

  Passover begins on the 15th day of the Hebrew month of Nisan which falls between March 26 and April 25 of the Gregorian calendar. The Rabbinical Jewish calendar aligns with the solar calendar so that 15 Nisan always coincides with Sunday, Tuesday, Thursday, or Saturday. In 2025, 15 Nisan coincided with Sunday, April 13, meaning Pesach started at sundown on Saturday, April 12. Ancient Israel held that the lunar new year would not start until barley was ripe as a test for spring onset. If barley was not eared out properly, an intercalary month called Adar II would be added before Nisan began. Since the 4th century, intercalation has been fixed mathematically according to the Metonic cycle instead of relying on witness testimony. Karaites use a different calendar relying on visual identification of ripe barley before determining the date. Samaritans employ a calendrical system sometimes matching the Rabbinic date but other times falling two days or even a full month later. In 2024, Rabbinical Passover began at sunset on the 22nd of April while the Samaritan calendar also marked the 22nd of April 2024 as their sacrifice day. Jews outside Israel celebrate the festival for eight days whereas Reform and Reconstructionist Jews usually observe it over seven days.

• 4. Prohibition Of Leaven

  ›

  Leaven in Hebrew chametz is made from one of five types of grains combined with water and left standing for more than eighteen minutes. The consumption, keeping, and owning of chametz is forbidden during Passover under Halakha. Yeast and fermentation are not themselves forbidden since wine remains required rather than merely permitted. Observant Jews spend weeks before Passover cleaning homes thoroughly to remove all chametz from every part of the house. Jewish law requires eliminating olive-sized or larger quantities of leavening from possession though most housekeeping goes beyond this minimum. Even seams of kitchen counters get cleaned to remove traces of flour and yeast however small they may be. Any containers or implements that touched chametz are stored away and never used during Passover. Some hotels and cruise ships across America, Europe, and Israel undergo thorough housecleaning to make premises kosher for Pesach. Chametz does not include baking soda or baking powder which leaven by chemical reaction instead of biological fermentation. Ashkenazi Jews historically refrain from eating kitniyot like legumes rice maize despite no clear commandment including them in chametz category. Sephardi Jews have always permitted eating kitniyot on Passover while Reform movement allowed it since 19th century.
