The ordered Passover meal commanded in Exodus 12 and retold annually by Jewish families across the Diaspora. Hebrew seder (order) names the prescribed sequence: the meal follows a fixed structure with specific elements eaten in specific order, each carrying symbolic significance. The Mosaic essentials — bitter herbs (recalling the bitterness of Egyptian slavery), unleavened bread (the haste of departure), roasted lamb (the substitutionary blood sprinkled on the doorposts) — were elaborated in post-biblical Jewish tradition into the fifteen-step modern Seder with its four cups of wine, the asking of the four questions by the youngest child, the recitation of the Haggadah (the story of the exodus), the closing prayer Next year in Jerusalem. Christ instituted the Lord's Supper at a Passover Seder (Matt 26; Mark 14; Luke 22; the precise chronology between Synoptics and John has been long discussed), specifically reframing two of its elements: the bread became His body broken, the cup became His blood of the new covenant. The continuity is theologically loaded: the meal that commemorated the original deliverance becomes the meal that commemorates the greater deliverance accomplished through the true Passover Lamb.
