What OpenAI's Newest Codex Found In The World's Oldest Codex: Hunting in the Bible

When I was a kid, my friend's dad found a new largest prime number. He had added one small step to a continuous record humanity has kept alive since Euclid. I thought it was awesome.

There are about half a million known valid verse-to-verse cross-references in the Bible. Scholars over two thousand years of scholars have presumably found most of what's there.

Could we find actually new ones with Codex 5.5?

What makes a cross-reference good

A strong cross-reference generally has:

• some textual intersection (we are using the Septuagint here, because the New Testament writers often quoted Greek scripture)
• a conceptual parallel, meaning the same kind of scene or argument is being replayed
• and a theological impact, meaning the parallel actually changes how you read the later passage.

A few are below.

I. Isaiah 37:16 ↔ Luke 4:5

O LORD of hosts, the God of Israel, who is enthroned above the cherubim, You are the God, You alone, of all the kingdoms of the earth. You have made heaven and earth.
Isaiah 37:16 (NASB95)

And he led Him up and showed Him all the kingdoms of the world in a moment of time.
Luke 4:5 (NASB95)

The year is 701 BC. Sennacherib commands the dominant army of the age and has just rolled through forty-six fortified Judean cities (his own annals brag the number) on his way to Jerusalem. The Assyrian empire is the largest the world has yet seen. By every visible measure, the lord of the inhabited world is the man at the city gate, not the God in the temple. Hezekiah is in a corner.

Sennacherib makes the point explicit. He stands beneath the wall and shouts a propaganda speech in Hebrew so the defenders can hear: Yahweh is just another local deity. This civilization had its gods. That one had its gods. None of them survived. Why should this one be different? A taunting letter follows.

Hezekiah carries it into the temple, spreads it open before God, and prays. You alone are God of all the kingdoms of the earth. Sennacherib is the only visible power here, yet Hezekiah, against worldly evidence, prays to the one he believes is the true sovereign, YHWH.

Seven centuries later, around 27 AD and around the same location, Jesus is forty days into a fast. The devil takes him up, shows him every kingdom on earth in an instant, and makes an offer. Luke does not hide the brokerage claim. I will give You all this domain and its glory; for it has been handed over to me, and I give it to whomever I wish.

Satan presents himself as the kingdoms' current owner. The visible sovereign in this scene is the prince of this world--arguably the one behind Sennacherib, 700 years hence.

What is the connection? The phrase Isaiah uses is unusual in Greek. The standard idiom for "kingdoms of the earth" uses γῆ, the ordinary word for ground or land. Isaiah picks οἰκουμένη instead, "the inhabited world." Across the entire Greek Bible, Old Testament and New, that variant appears only three times.

• Isaiah 23:17. Tyre, after seventy years, restored as a trading hub "to all the kingdoms of the inhabited world."
• Isaiah 37:16. Hezekiah's prayer, above.
• Luke 4:5. The wilderness temptation, above:

καὶ ἀναγαγὼν αὐτὸν ἔδειξεν αὐτῷ πάσας τὰς βασιλείας τῆς οἰκουμένης
and leading him up he showed him all the kingdoms of the inhabited world.

The Greek beneath the English is the same in both cases across Isaiah 37:16 and Luke 4:5. Once that's visible, the two scenes are part of one question: who actually has these kingdoms?

As proof of who these kingdoms really belong to, the angel of YHWH killed 185,000 Assyrian soldiers in one night. However, Jesus elsewhere calls Satan the ruler of this world, and when Satan claims in the wilderness that they have been handed over to him, Jesus does not dispute the claim. It appears that Satan steps into a sharper version of Sennacherib's role: visible sovereign for now, usurper that is already-but-not-yet defeated.

One way to read the whole Bible is as the story of a throne. Adam was given dominion over the earth and lost it. Hostile powers have run the kingdoms ever since, sometimes through a Sennacherib, sometimes through other vessels. But Hezekiah's prayer reveals faith in the true king. Jesus refuses the counterfeit transfer that would have made him a vassal of the broker, and takes the long road back: cross, tomb, resurrection, and rightful sovereignty over all the kingdoms of the world.

II. Genesis 29:10 ↔ Matthew 28:2

When Jacob saw Rachel the daughter of Laban his mother's brother, and the sheep of Laban his mother's brother, Jacob went up (προσελθὼν) and rolled the stone (ἀπεκύλισεν τὸν λίθον) from the mouth of the well and watered the flock of Laban his mother's brother.
Genesis 29:10

And behold, a severe earthquake had occurred, for an angel of the Lord descended from heaven and came (προσελθὼν) and rolled away the stone (ἀπεκύλισεν τὸν λίθον) and sat upon it.
Matthew 28:2

~1800 BC. Jacob is on the run. He has stolen his brother Esau's blessing, and Esau has sworn to kill him for it. He flees to Haran and arrives at a well outside the city, where three flocks of sheep wait beside a stone too heavy for one shepherd to move. The local custom is to wait until every flock arrives and the shepherds combine their strength. Then Rachel arrives with her father's sheep. Jacob rolls the stone himself, waters her flock, kisses Rachel, and weeps. The betrothal that births the twelve tribes of Israel begins at this stone.

Roughly eighteen centuries later, ~30 AD, on the third morning, an angel descends from heaven, rolls away the stone sealing Jesus' tomb, and sits on it. The earth shakes. The Roman guards collapse like dead men. Mary Magdalene and the other Mary arrive, find the grave empty, and meet the risen Christ on the road back to the disciples.

The Greek for "rolled away the stone" in Matthew 28:2 is ἀπεκύλισεν τὸν λίθον, and this phrase occurs only twice in the entire Greek Bible. The other place is Genesis 29:10.

Apparently, betrothal at a well is core to the Hebrew cultural narrative: Isaac and Rebekah in Genesis 24, Jacob and Rachel in Genesis 29, Moses and Zipporah in Exodus 2. A man arrives in a foreign country, comes to a well, encounters a young woman, water is drawn, marriage follows. Jesus carries the type forward in John 4 at Jacob's literal well with a twist, asking a Samaritan woman for a drink and offering her living water in return.

Could this simple textual similarity point to something deeper? Matthew calls Jesus the bridegroom more than once (Matt 9:15, 22, 25). Paul names the church his bride in Ephesians 5. Revelation closes with the wedding supper of the Lamb. At the empty tomb, Matthew stages the type-scene at the threshold of that consummation. The bridegroom has returned from the farthest country, which is death. The stone is rolled away. The women arrive. They are the first to meet him on the other side. Christ, the well of living water, is risen.

The stone that sealed death becomes the stone that opens the betrothal for multitudes to find salvation.

OpenBible and TSK do not link Genesis 29:10 to Matthew 28:2. The exact verbal match goes unflagged, and the typological reading with it. Matthew's resurrection scene is more than victory over the grave. It is the bridegroom emerging from the tomb to meet his bride.

III. 1 Kings 18:34 ↔ John 2:7

Then he said, 'Fill four pitchers with water (ὑδρίας ὕδατος) and pour it on the burnt offering and on the wood.' And he said, 'Do it a second time,' and they did it a second time. And he said, 'Do it a third time,' and they did it a third time.
1 Kings 18:34

Jesus said to them, 'Fill the waterpots with water (ὑδρίας ὕδατος).' So they filled them up to the brim.
John 2:7

~860 BC. Israel is three years into a drought Elijah called down. King Ahab and Queen Jezebel have led the country into the worship of Baal, the Canaanite storm-god who is supposed to deliver rain. Elijah summons all Israel to Mount Carmel and stages a contest: two altars; whichever god answers with fire is God in Israel.

The prophets of Baal cry out from morning to evening. They cut themselves. Nothing happens. Then Elijah builds his altar, lays the wood, cuts up the bull, and issues a strange command: fill four pitchers with water and pour them on the offering. He has it done three times. The altar is drenched, the trench around it filled. Elijah prays, and the fire of YHWH falls and consumes everything: the bull, the wood, the stones, the dust, even the water.

Roughly nine centuries later, around 27 AD, Jesus attends a wedding feast at Cana with his mother and disciples. The wine runs out. Mary tells him. Jesus says his hour has not yet come, but he acts anyway. Six stone water jars (symbolizing incompleteness/the flesh, one less than seven) stand nearby for the Jewish rite of purification. Jesus says, "Fill the waterpots with water." The servants fill them to the brim. He has them draw some and take it to the headwaiter, who does not know where it came from and tells the bridegroom this is the best wine yet. Wine, of course, symbolizes the blood of Jesus. What could be more purifying?

The Greek for "water jars of water" is ὑδρίας ὕδατος. It occurs only twice in the entire Greek Bible. Both occurrences are above.

The occurrences coincide with one question: who is God in Israel? Elijah's water turns to fire and answers by burning. Jesus' water turns to wine and answers by overflowing.

OpenBible and TSK do not link 1 Kings 18:34 to John 2:7.

IV. Jeremiah 13:18 ↔ Luke 1:52

Say to the king and the queen mother (δυναστεύουσιν, "the ruling ones"), "Take a lowly seat (ταπεινώθητε), for your beautiful crown has come down (καθῃρέθη) from your head."
Jeremiah 13:18

He has brought down (καθεῖλεν) rulers (δυνάστας) from their thrones, and has exalted those who were humble (ταπεινούς).
Luke 1:52

~597 BC. Babylon is at the gate. King Jehoiachin has been on the throne three months, after his father died in the middle of Nebuchadnezzar's siege. The royal household includes his mother Nehushta, the queen mother. Jeremiah says to the king and the ruling ones (δυναστεύουσιν): take a lowly seat (ταπεινώθητε). The crown of glory has come down (καθῃρέθη) from your head. Within weeks, Jehoiachin and his mother will be marched to Babylon as prisoners.

Roughly six centuries later, around 5 BC, an unknown peasant girl from Nazareth has just learned from Gabriel that she will conceive the Son of the Most High. She visits her cousin Elizabeth. The unborn John leaps in Elizabeth's womb. Mary opens her mouth and sings. He has brought down (καθεῖλεν) rulers (δυνάστας) from their thrones, and has exalted those who were humble (ταπεινούς).

The Greek of Jeremiah 13:18 in the LXX has three distinct roots: δυναστ- (ruling), ταπειν- (humbled), καθαιρ- (brought down), which reappear in Luke 1:52. Standard Magnificat references, Hannah's song (1 Sam 2:7-8) and Psalm 113, share generally one root with Luke 1:52, whereas this location in Jeremiah shares three.

Jeremiah foretold the coming down and emptying of the Davidic crown itself. However, the Magnificat is sung by the mother of the true Davidic king while he is still in her womb. The crown Jeremiah said came back on its rightful head, flipping former slaves to free sons of God.

OpenBible and TSK do not link Jeremiah 13:18 to Luke 1:52.

V. Deuteronomy 28:48 ↔ 2 Corinthians 11:27

therefore you shall serve your enemies whom the LORD will send against you, in hunger (ἐν λιμῷ), in thirst (καὶ ἐν δίψει), in nakedness (καὶ ἐν γυμνότητι), and in the lack of all things; and He will put an iron yoke on your neck until He has destroyed you.
Deuteronomy 28:48

I have been in labor and hardship, through many sleepless nights, in hunger (ἐν λιμῷ) and thirst (καὶ δίψει), often without food, in cold and exposure (καὶ γυμνότητι).
2 Corinthians 11:27

~56 AD. Paul writes to Corinth from Macedonia. Rival missionaries have called him untrained and weak. A true apostle, he thinks, should look like the one who sent him. So he responds with what he calls boasting like a fool, listing exactly what they consider disqualifying. Thirty-nine lashes five times. Three beatings with rods. One stoning. Three shipwrecks. Dangers from rivers and robbers and false brothers. Hunger (ἐν λιμῷ) and thirst (καὶ δίψει). Fastings. Cold and nakedness (καὶ γυμνότητι).

The three nouns λιμός, δίψος, γυμνότης appear together, in the same order and the same form, in the entire Greek Bible exactly twice. Here and Deuteronomy 28:48.

Moses, in Deuteronomy 28, lists what will happen if Israel keeps the covenant and what will happen if Israel breaks it. The curses escalate: drought, plague, defeat, deportation. Serving enemies in hunger (ἐν λιμῷ), thirst (καὶ ἐν δίψει), nakedness (καὶ ἐν γυμνότητι), and lack of everything, with an iron yoke on the neck until destruction.

But why would Paul bear the curses if he did not break the covenant? He who first bore the curses also did not break the covenant, but was the new covenant.

Cursed is everyone who hangs on a tree. (Gal 3:13)

Always carrying about in the body the dying of Jesus, so that the life of Jesus also may be manifested in our body (2 Cor 4:10).

Paul wears the curse because he is in Christ, and Christ took the curse. The same words that meant Israel's judgment now mark the apostle of the one who absorbed them, the new Israel: Hunger, thirst, nakedness.

OpenBible and TSK do not link the two verses.

VI. 2 Chronicles 6:26 ↔ Matthew 1:21

When the heavens are shut up and there is no rain, because they have sinned against You, and they pray toward this place and confess Your name, and turn from their sin (ἀπὸ τῶν ἁμαρτιῶν αὐτῶν) when You afflict them
2 Chronicles 6:26

She will bear a Son; and you shall call His name Jesus, for He will save His people from their sins (ἀπὸ τῶν ἁμαρτιῶν αὐτῶν).
Matthew 1:21

~960 BC. Solomon has just finished building the temple and stands before it to dedicate it. He prays a long covenant prayer, rehearsing every scenario in which Israel will need forgiveness. If they sin and are defeated, if they sin and there is drought, if they go into exile. The people would turn from their sins (ἀπὸ τῶν ἁμαρτιῶν αὐτῶν), pray toward the temple, and YHWH would forgive.

Nearly a thousand years later, an angel appears to Joseph in a dream. Mary is pregnant by the Holy Spirit. The angel names the child Jesus (Yeshua, "YHWH saves," from the Hebrew root yasha, "to save"), for he will save (yoshia) his people from their sins (ἀπὸ τῶν ἁμαρτιῶν αὐτῶν).

The shared Greek between the two verses is ἀπὸ τῶν ἁμαρτιῶν αὐτῶν, which means "from their sins;" that exact four-word phrase appears in the entire LXX/NT corpus only four times. The three Old Testament occurrences are all temple-context: 1 Kings 8:35 and 2 Chronicles 6:26 (the two accounts of Solomon's prayer) and Ezekiel 43:10 (the new-temple vision). The fourth and only New Testament reference spoken from the lips of an angel at the naming of our savior.

The chosen place gives way to the chosen person. Where Solomon prayed toward a building, the angel announces a son. When a Samaritan woman later asks Jesus where the right place to worship is (on Mount Gerizim or in Jerusalem), he refuses both. The hour is coming, he tells her, when the Father will be worshiped neither here nor there but in spirit and truth (John 4:21-23). The where-question has dissolved into the who-question. The son is himself the place (John 2:21, "the temple of his body").

And by his very name, the son is YHWH. The place Solomon prayed toward has become a person, and the person is the God Solomon was praying to. OpenBible and TSK do not link 2 Chronicles 6:26 to Matthew 1:21.

VII. Job 22:9 ↔ Luke 1:53

You have sent widows away empty (ἐξαπέστειλας κενάς), and afflicted the orphans.
Job 22:9

He has filled the hungry with good things, and sent the rich away empty (ἐξαπέστειλεν κενούς).
Luke 1:53

Job may be the oldest story in the Bible. A righteous man loses everything, and his friends arrive to comfort him. The comfort takes the form of accusation: Job must have done something to deserve this. Eliphaz, one of these friends, lists the crimes he assumes Job committed. One of them is sending widows away empty. God later tells Eliphaz and the others they were wrong: not just about Job, but about Him.

The Magnificat is the opening song of the New Testament. A teenage girl, unmarried and pregnant by the Holy Spirit, has every reason to be terrified of what her village will conclude. Instead she is filled with the Spirit, and what comes out of her is a song about God filling the hungry and sending the rich away empty. The God she praises sides with people in her exact position.

The link is a rare Greek pairing, ἐξαποστέλλω + κενός. In the chronological opener of the Old Testament, from Eliphaz's mouth it was a false accusation against a righteous man. In the beginning of a new age and a New Testament, from Mary's mouth it is an accurate description of what God does to the actual oppressors and a deep statement of His nature.

The same logic Eliphaz applies to Job is the foundational logic of all human religion. René Girard, the French anthropologist and Stanford professor, came to this observation as an atheist. In nearly every ancient culture, when a crisis broke out, the community would find a scapegoat, kill or exile them, and order would return. The victim was assumed to deserve it. The gods were assumed to approve. Girard expected to find the same pattern in the Bible, but he found the opposite. His discovery was part of what brought him back to Christianity.

The Bible breaks the pattern. God insists on the innocence of the victim and sides against the crowd. He tells Eliphaz and Job's other "friends" they were wrong. He sends his Son to be born through a girl who, by all social standards, should have been the next scapegoat. Instead, she sings His praise.

Mary's song names the actual targets of judgment: the rich, the proud, the comfortable. Jesus will say the same thing later in plainer words: the last shall be first, and the first shall be last.

VIII. Psalm 44:23 ↔ Luke 22:46

Arouse Yourself, why do You sleep (ὑπνοῖς), O Lord? Awake (ἀνάστηθι), do not reject us forever.
Psalm 44:23

Why are you sleeping (καθεύδετε)? Get up (ἀναστάντες) and pray that you may not enter into temptation.
Luke 22:46

Israel calls out to God in Psalm 44, having been defeated, scattered, and mocked. They claim faithfulness ("we have not forgotten You, nor have we dealt falsely with Your covenant"), yet they are crushed. This culminates in a cry out to God, accusing him of being asleep.

Later, we find Jesus in Gethsemane, having asked his disciples to stay awake. He is in such agony that his sweat falls like drops of blood. He rises from prayer, finds them sleeping, and says:

τί καθεύδετε; ἀναστάντες προσεύχεσθε
Why are you sleeping? Get up and pray.

The sleep verbs differ (ὑπνόω in the psalm, καθεύδω in Luke) so this is not text intersection but a similarity found through rhetorical pattern: the same why-sleeping question, followed by an imperative built from the same root, ἀνίστημι. OpenBible and TSK do not link the two.

Instead of Israel crying out to God, God pleads with man. The Son is put in the position of the psalmist. Israel's cry is answered with God coming down to earth, taking the burden of our suffering so completely that He who is abandoned is the Son, one of our triune God.

IX. Job 32:19 ↔ Luke 5:38

Jesus' parable of the new wine and new wineskins is usually treated as having no Old Testament antecedent.

Job 32:19 has it. Elihu, before he speaks:

"Behold, my belly is like wine that has no vent; like new wineskins it is ready to burst."

The LXX renders the verse as:

ἀσκὸς γλεύκους ζέων δεδεμένος ἢ ὥσπερ φυσητὴρ χαλκέως ἐρρηγώς,
"a bound wineskin of fermenting sweet wine, or like the burst bellows of a smith."

(The bellows image is an LXX addition not present in the Hebrew at all.) The bridge to Luke is real on the Greek side: the LXX uses ἀσκός, the same noun Luke uses with ἀσκοὺς καινούς. What's missing on the Greek side is καινός (new). The LXX has the vessel and the pressure, but lets the "newness" qualifier drop. The picture, though, is the same: wine under pressure, a vessel about to burst.

The standard reading of Luke 5:38 treats it as a saying about freshness: old forms can't accommodate new content. Job sharpens it. New wine is not passive content waiting for a container; it exerts pressure that the vessel has to bear. Elihu uses the image for the inward pressure of speech he can no longer hold in. Jesus uses it for covenantal incompatibility: the kingdom is fermenting reality, and old religious forms aren't merely outdated, they will rupture under the pressure of what is now arriving.

What the nine findings share, beyond the Greek bridge, is where they ultimately point. Elijah's water becomes wine because the prophet's covenant lawsuit has been resolved into the wedding the prophets were preparing the road for. The widow's emptiness becomes the rich man's judgment because Christ is on his way. The crown comes down because the new king is coming. The temple-located forgiveness becomes a person's name because the chosen place gives way to the chosen person. Satan's offer of the kingdoms is exposed as parody because the kingdoms already belong to the Father. The wineskin bursts because what is now arriving cannot be held by what was. The lament about a sleeping God becomes a question put to sleeping disciples because God himself has now come into the lament. The stone is rolled away from the well so that the bride can be gathered, and rolled away from the tomb so that the bride can be gathered. Paul's hunger is covenant curse because the cursed one has already been raised. Every cross-reference, in the end, references the cross.

Jesus is everywhere in scripture. Not as a code to decode, but as the gravity that bends all the lines.

That is what a model can help with, in a small way. AI is not God. But it can point to God, and at its best deepen our understanding of God. To contribute even one stone to that work is a blessing.

I've built something in that spirit at communion.com. It tells you what a verse means, synthesizing centuries of commentary from celebrated theologians. It's available now. I hope you'll try it.

Notes on attestation

I came to all nine connections through the pipeline above, working independently. In subsequent research before posting I turned up three prior partial attestations worth disclosing.

Job 32:19 ↔ Luke 5:38. A user-submitted link from Job 32:19 to Matthew 9:17 (the synoptic parallel of Luke 5:38) exists in OpenBible's dataset, but at negative 1 votes — actively voted against by the community. The connection is absent from TSK and from peer-reviewed scholarship.

Psalm 44:23 ↔ Luke 22:46. Two prior partial attestations exist. OpenBible already links Psalm 44:23 to Mark 4:38, where the disciples wake Jesus during the storm. And the apparatuses link Luke 22:46 to Jonah 1:6, where a sailor wakes the sleeping prophet. The wake-the-sleeper formula has been recognized for a long time. What is novel is the cross between Psalm 44 and Luke 22:46 specifically, where the role flips: Jesus, in the lamenter's role, asking his disciples the question Israel reserved for asking Yahweh.

Genesis 29:10 ↔ Matthew 28:2. A 2024 devotional post on Unreached Network ("Jacob's Easter Moment") notes the rare verb shared between the LXX of Genesis 29 and the resurrection accounts. That is one niche prior attestation, post-dating the standard apparatuses. The connection is absent from TSK, OpenBible's set, and from peer-reviewed scholarship.
