Built from the Old Testament feast architecture first, then verified against the New Testament texts. Scripture references only — no tradition assumed.
Lamb selected Nisan 10, kept until Nisan 14, killed "between the two evenings." Blood applied, flesh eaten that night with unleavened bread. Nothing remains until morning.
The first day of Unleavened Bread is a holy convocation — no customary work. This is an annual Sabbath regardless of what weekday it falls on. Distinct from the weekly seventh-day Sabbath.
Jonah was three days and three nights in the fish. Jesus said this is the only sign given to the generation. The conjunction "and" specifies both components — not merely "the third day."
The wave sheaf offered "the day after the Sabbath." Paul identifies Christ as "the firstfruits of those who have fallen asleep." The resurrection fulfills this feast offering.
Jesus enters Jerusalem on a donkey (Zech 9:9). The crowd receives him. On the same day the OT commands every household to select their Passover lamb, Jesus — the Lamb of God (Jn 1:29) — presents himself to Israel.
Pharisees, Sadducees, and scribes examine Jesus with questions on taxes, resurrection, the greatest commandment. He is found "without blemish" — no one can trap him (Mk 12:34). Mirrors the four-day inspection of the Passover lamb from Nisan 10 to 14.
The disciples "prepare the Passover" (Mk 14:12-16). Jesus eats with the twelve. He breaks bread and shares the cup — but no lamb is explicitly mentioned at this meal in any gospel. Only bread and wine.
John says this supper was "before the feast of Passover" (Jn 13:1). When Judas leaves, others assume he's going to "buy those things we need for the feast" (Jn 13:29) — impossible if the feast had already started. The meal is a pre-Passover supper, not the official seder.
Jesus prays in agony. Luke records sweat like drops of blood and an angel strengthening him. Judas arrives with a crowd. Peter cuts off Malchus' ear (named only in John). All four gospels attest. The disciples flee.
Jewish trial before Caiaphas — accused of blasphemy. Peter denies three times before the rooster crows (all four gospels). Sent to Pilate at dawn. Pilate finds no fault. Barabbas released.
The Jewish leaders refuse to enter Pilate's hall "lest they should be defiled, but that they might eat the Passover." They have NOT yet eaten the Passover seder. The official Temple slaughter and seder meal are still ahead — confirming this is the morning of Nisan 14, before the feast.
Jesus is crucified at the third hour (Mk 15:25). Darkness covers the land from the sixth to ninth hour. He dies at the ninth hour — the exact time the Passover lambs were being slaughtered in the Temple (Josephus records slaughter from the 9th to 11th hours). Paul declares: "Christ, our Passover, was sacrificed for us" (1 Cor 5:7). The type and antitype align to the hour.
Joseph of Arimathea takes the body. Buried hastily in a new tomb. The urgency: the High Sabbath begins at sunset. Deuteronomy 21:22-23 requires a body not remain on the tree overnight. John confirms: "for that Sabbath was a high day" (Jn 19:31) — this is the annual feast Sabbath of Nisan 15, not the weekly Sabbath.
This is the High Sabbath John references (Jn 19:31). It is the first day of the Feast of Unleavened Bread — an annual commanded rest. The women cannot buy or prepare spices. Guards seal the tomb and set the watch (Mt 27:62-66). Jesus is in the tomb.
Mark 16:1 — the women bought spices "when the Sabbath was past."
Luke 23:56 — they prepared spices, then "rested on the Sabbath according to the commandment."
They buy spices after a Sabbath and prepare them before a Sabbath. This is only possible if two different Sabbaths bracket this day — the High Sabbath (Thursday) and the weekly Sabbath (Saturday), with Friday as the workday between them.
Luke specifies they rested "according to the commandment" — the fourth commandment, the weekly seventh-day Sabbath (Ex 20:8-11). This is distinct from the annual High Sabbath of Thursday. Matthew 28:1 uses Greek opse de sabbaton — argued by several scholars to be genitive plural: "after the Sabbaths," pointing to the end of both rest days.
Jesus rises at or just after sunset Saturday — completing three full days and three full nights. By Hebrew reckoning, sunset Saturday is the start of the first day of the week. The tomb is not opened FOR him — it was opened so the women could see he was ALREADY gone. Mark 16:9 can be punctuated: "Now having risen, early the first day of the week he appeared…" — distinguishing the time of rising from the time of appearing.
The women come with the spices they purchased Friday and prepared before the weekly Sabbath. They find the stone rolled away and the tomb empty. Angels declare: "He is not here; He is risen." The text never says Jesus rose on Sunday morning — it says the tomb was found empty on Sunday morning. The resurrection occurred the previous evening.
Starting from burial before sunset Wednesday (end of Nisan 14) and counting to sunset Saturday (end of Nisan 17):
Result: Three days and three nights — exactly as Jonah was three days and three nights in the belly of the great fish (Jonah 1:17), and exactly as Jesus declared would be the only sign given (Matthew 12:40).
