Jesus refuses every sign to "an evil and adulterous generation" — except one. "There shall no sign be given to it, but the sign of the prophet Jonas: for as Jonas was three days and three nights in the whale's belly; so shall the Son of man be three days and three nights in the heart of the earth" (Matthew 12:39–40). This makes Jonah the only OT figure whose typological function Jesus states in his own person, in direct answer to a demand for proof. The Jonah narrative in the book itself already speaks in the first person of death and resurrection: from the fish's belly Jonah prays "Out of the belly of hell cried I" (Jonah 2:2) and acknowledges that God "brought up my life from corruption" (2:6) — the prophet voices entombment and deliverance before emerging to complete his mission. Chrysostom reads the "sign of Jonas" passage as the moment Jesus "strikes the first note of the doctrine of His resurrection, and confirms it by the type" — the typology is not illustrative decoration but the evidentiary ground for believing the resurrection before it occurs. Aquinas, compiling the Catena Aurea, addresses the chronological problem directly: the interval from Friday afternoon to Sunday morning does not straightforwardly equal "three days and three nights," and he resolves it through the biblical idiom of putting the part for the whole, a standard principle of scriptural computation. The Nineveh dimension extends the typology: Henry draws the full parallel — "Jonas being cast into the sea, and lying there three days, and then coming up alive and preaching repentance to the Ninevites... so shall the death and resurrection of Christ, and the preaching of his gospel immediately after to the Gentile world, be the last warning to the Jewish nation." Jonah's emergence from death-in-the-fish enables his mission to pagans; Christ's resurrection enables the apostolic mission to all nations. Luther's summary is characteristic in its brevity: Jonah has only four chapters, yet through his weakness moved an entire kingdom — "justly a figure and a sign of the Lord Christ."
What the primary sources show
"An evil and adulterous generation seeketh after a sign; and there shall no sign be given to it, but the sign of the prophet Jonas: for as Jonas was three days and three nights in the whale's belly; so shall the Son of man be three days and three nights in the heart of the earth." — the only sign Christ offers as proof of his messiahship; the typological parallel is structural (three days), locative (buried), and directional (emergence into renewed mission).
"There shall no sign be given to it, but the sign of Jonas the prophet. Now is He striking the first note of the doctrine of His resurrection, and confirming it by the type." — Chrysostom identifies the Jonah appeal not as illustration but as pre-announcement: Jesus is using the OT type as advance evidence for the resurrection, making Jonah's three days in the fish a prophetic guarantee of what is to come.
