You're reading Matthew. You hit chapter 1, verse 23: "Behold, the virgin shall conceive and bear a son, and they shall call his name Immanuel." Matthew says this fulfills a prophecy from Isaiah.
You flip back to Isaiah 7:14. The original context turns out to be a confrontation between the prophet and a wicked king named Ahaz, threatened by an army from the north. The "virgin" — actually, the Hebrew word can also mean "young woman" — is going to bear a son named Immanuel as a sign to Ahaz that the threatening kings will fall before the boy is old enough to choose food.
The instinct of any honest reader: "Wait. That doesn't sound like it's about Jesus at all. Is Matthew misusing the verse?"
When Matthew quotes Isaiah, is he twisting the original meaning?
This is the question Page 12 answers. The short answer: no, but only because he's making a series of careful interpretive choices that the Old Testament itself trained him to make. Walking through those choices is what this page is about.
The framework comes from Schnittjer & Harmon's How to Study the Bible's Use of the Bible. They identify seven specific decisions every careful reader makes when one biblical author uses another. The methodology behind every Intertextuality Pair on this site runs on these seven choices.
Before the seven choices, the premise: the Bible interprets itself, and does so contextually.
"The authors of the New Testament did not invent a new hermeneutic. They followed the well-worn interpretive path used by prophets, psalmists, narrators, visionaries, and sages of Israel's scriptures."
Notice what that sentence claims. The NT authors aren't doing something exotic to the OT. They're doing what Old Testament authors had been doing to each other for centuries. Deuteronomy interprets and advances Exodus. Chronicles interprets and advances Samuel-Kings. The prophets interpret and advance the Torah. By the time Matthew picks up Isaiah, he's stepping into an established practice.
That changes the question. It's not "Is Matthew allowed to read Isaiah this way?" It's "How did the OT itself train its readers to read this way?" The seven choices spell that out.
Are the Old and New Testaments two separate books that happen to share covers? Or are they one organic whole?
The dominant trend in modern scholarship has been to treat the OT as having meanings unrelated to NT fulfillment — to read each testament "in isolation," as if the NT authors are forcing alien meanings onto OT texts. This is the sequestered reading.
The biblical authors themselves treat Scripture as connected. They display "canonical consciousness" — awareness that earlier Scripture is authoritative and that they are writing into a continuous story.
Two principles drive this:
Practical consequence: When studying how a NT author uses an OT text, first examine how that OT text was already being developed within the OT canon, before looking outside it. The NT is usually picking up a thread the OT has already been pulling.
Did NT authors distort the original meaning of OT texts to make them about Christ? Or did they legitimately advance revelation within the text's original meaning?
This is the heart of the worry. If Matthew is quoting Isaiah 7:14 about a sign to King Ahaz and applying it to Jesus' birth 700 years later, isn't he changing the meaning?
The biblical authors' answer is no — they are advancing revelation, not adjusting meaning. Three things make this work:
The contrast looks like this:
| Problematic view | Biblical view |
|---|---|
| NT authors adjust OT meaning | NT authors advance OT revelation |
| NT borrows extrabiblical methods | NT follows OT interpretive precedents |
| Meaning changes between testaments | Meaning deepens and is fulfilled |
| Spirit adds new meaning | Spirit illuminates intended meaning |
Practical consequence: Before concluding that a NT use of the OT is "noncontextual," check whether the OT text itself contains forward-pointing elements, and whether other OT texts had already developed that passage further.
When you suspect that one biblical text is referring to another, is identifying the allusion a precise science with clear criteria, or interpretive judgment?
It's both. There are clear criteria, and there is judgment. You need both.
The vocabulary to know:
| Term | What it means |
|---|---|
| Quotation | Explicit verbal repetition, often marked ("as it is written") |
| Paraphrase | Intentional rewording of the donor text |
| Allusion | Intentional evocation without explicit citation |
| Echo | Subtle resonance where intentionality is uncertain |
| Trace | Possible connection, speculative |
The site uses these distinctions. Blue highlights in The Bible mark quotations; green marks allusions; amber marks echoes. (See Page 04 Quick Reference.) The reason for the gradient is exactly this — different levels of certainty about whether an intertextual connection is intentional.
The five tests for identifying an allusion:
The risk to avoid: parallelomania — finding connections everywhere. Stock phrases and lyrical idiom can create false positives. The cleanest allusions stack multiple indicators; uncertain cases get treated as echoes (amber) rather than confident quotations (blue).
Practical consequence: Use methodological rigor; hold conclusions with humility. The cleaner the indicators, the bolder the color.
When interpreting a text, do you focus only on the immediate paragraph and chapter (horizontal context), or also on the network of intertextual connections it sits within (vertical context)?
You need both.
Some passages function as anchor texts — passages around which extensive networks of allusion form. The classic example is Exodus 34:6–7, the "attribute formula" ("The LORD, the LORD, a God merciful and gracious, slow to anger, and abounding in steadfast love…"). This text is quoted or alluded to over 30 times across the Old Testament. Each new use carries forward the cumulative theological weight of all the previous uses. By the time you reach the New Testament, the formula is doing enormous work.
Practical consequence: When studying a text, trace its allusions both backward (to earlier texts) and forward (to later texts). Don't flatten meaning to horizontal context only. Vertical connections add theological depth — and the original audience expected you to hear them.
When interpreting a NT use of the OT, should you prioritize parallels from other biblical texts, or from extrabiblical Jewish literature (Second Temple texts, rabbinic writings, Dead Sea Scrolls)?
Biblical parallels first. Extrabiblical literature provides comparative context, but is secondary.
The order matters:
1. START → Biblical parallels (OT → OT, NT → OT)
2. → Extrabiblical parallels (for comparison)
3. → RETURN to biblical interpretationWhy this order? Because extrabiblical sources have problems biblical sources don't:
Extrabiblical sources are valuable for comparison and contrast — they show what the interpretive environment looked like — but they don't determine biblical meaning.
Practical consequence: When studying Paul's use of Genesis 15:6, first trace how the OT itself develops this text (Psalm 106:30–31, Nehemiah 9:8) before turning to Jewish interpretive traditions. The OT-to-OT trail almost always gets you to where Paul is going.
When the NT identifies an OT person, event, or institution as a "type" of Christ, is that type recognized only in retrospect, or did it contain forward-pointing expectation in its original context?
Both kinds are real. Page 11 walks through this in detail; the short version:
Both are valid because the criterion is divine intent (which was always present), not human author awareness (which may have come later).
The discipline against fanciful typology comes from the five tests (Page 11): correspondence, historicity, escalation, pointing-forwardness, retrospective interpretation. All five must pass.
Practical consequence: Don't limit typology to only the cases the NT explicitly names. But don't invent types either. Look for divine design in real redemptive history — and run every proposed type through the five tests.
The technical-sounding choice. Quick translation: when a biblical author quotes a speech from an earlier text, does he sometimes legitimately re-assign who's speaking, who's being addressed, or who's being talked about?
Yes. This is called prosopological exegesis (from Greek prosopon, "person/character"). It does not replace historical interpretation — it operates alongside it.
A worked example explains it best.
Hebrews 1:8–9 quoting Psalm 45:6–7
Original context (Psalm 45): A royal wedding song. The royal bride speaks to the human king, addressing him with elevated language: "Your throne, O God, is forever and ever..."
Hebrews 1:8–9: The author of Hebrews quotes the same verse but the speaker is now God, the addressee is now the Son.
What changed: The speaker (royal bride → God) and the referent (human king → Christ).
Why it works: Hebrews isn't ignoring the historical context. He's recognizing that the language of the psalm was always too elevated for any merely human king. The royal language was anticipating its true subject — and the divine voice was always implicit. The psalm has both meanings: it was true of the historical king as God's anointed, and it is true more fully of the Messiah as the divine Son.
Prosopological exegesis appears throughout Scripture:
This is not ahistorical. Hebrews 3:7 affirms David's authorship of Psalm 95 and the Holy Spirit's speech through it. Both are true. Both matter.
Practical consequence: When the NT applies an OT speech to a new speaker, referent, or addressee, this is a legitimate technique with OT precedents. It honors the original historical context while recognizing the fuller meaning the divine Author always intended.
Now back to where we started. Matthew quotes Isaiah and applies it to Jesus' birth. Walk it through the seven choices:
Step 1 — Identify the allusion (Choice 3). This is a quotation, not an allusion. Matthew explicitly cites it: "All this took place to fulfill what the Lord had spoken through the prophet." The signal is unmistakable; this lands as blue (direct quotation).
Step 2 — Connected, not sequestered (Choice 1). Matthew assumes you'll read Isaiah and Matthew as one canonical story. He's not making the OT serve a foreign agenda; he's claiming Jesus completes a story Isaiah was telling.
Step 3 — Horizontal context of Isaiah 7:14 (Choice 4). Isaiah is confronting King Ahaz during the Syro-Ephraimite war. God offers Ahaz a sign; Ahaz refuses. God gives him one anyway: "the virgin/young woman shall conceive and bear a son..." The sign confirms God's faithfulness in the present crisis — the threatening kings will fall before the boy is old enough to choose between good and evil.
Step 4 — Vertical context of Isaiah 7:14 (Choice 4). Now the deep context. Isaiah 7 sits inside Isaiah 7–12 — the Immanuel cycle, in which the name "Immanuel" recurs and develops. By Isaiah 9 the child has become "Wonderful Counselor, Mighty God, Everlasting Father, Prince of Peace," receiving David's eternal throne. By Isaiah 11 the child has become the root of Jesse, ruler over all nations, ushering in the new creation. The "young woman's son" of chapter 7 has been theologically escalated across the cycle into a divine, eternal king.
Step 5 — OT-to-OT first (Choice 5). Before turning to extrabiblical Jewish interpretation, Matthew (and we) follow the development inside the OT. The "Immanuel" sign in Isaiah was always going somewhere bigger than Ahaz's immediate moment; the OT itself developed it.
Step 6 — Advancement, not adjustment (Choice 2). Matthew is not changing what Isaiah said. He is recognizing that Isaiah's prophecy had a near-term partial fulfillment (a sign-baby in Ahaz's day) and a far-term complete fulfillment (the virgin-born Immanuel who is in fact God with us). The original meaning stands. The fuller meaning is its consummation.
Step 7 — Forward-looking type (Choice 6). Isaiah 7:14 is forward-looking. The text itself contains indicators (the name "Immanuel" — God with us; the elevated escalation across chapters 7–12) that anticipate something beyond the immediate sign. Matthew is recognizing what the text was already pointing to.
Step 8 — Prosopological dimension (Choice 7). Mild but present. Isaiah's "young woman" was a real woman in the eighth century BC; Mary is also a real woman in the first century AD. Both bear "Immanuel." But the referent of the name "God with us" differs in scope: a sign-child for one king, vs. the literal embodiment of God's presence in human flesh.
The result: Matthew has not twisted Isaiah. He has read Isaiah carefully, in full canonical context, recognizing the trajectory the prophet himself set in motion. The seven choices are how he got there.
When you encounter an OT quote or allusion in the NT:
This is the methodology behind every Intertextuality Pair on this site.
Open any Intertextuality Pair file and you'll see structured fields that correspond to these seven choices:
| Field | Choice it tracks |
|---|---|
| Reference Type (Quotation / Allusion / Echo) | Choice 3 — strength of the allusion |
| Source (TOSK / Gill / Beale-Carson / etc.) | Choice 5 — biblical and scholarly grounding |
| Connection Method(s) (Typology / Promise-Fulfillment / Analogy / etc.) | Choices 2 + 6 — how revelation advances and what kind of pattern |
| Significance (the analytical paragraph) | Choices 4 + 7 — full context, both horizontal and vertical |
| Related Trajectory Tables | Choice 1 — how this connection fits in the canonical story |
The 2,834 Intertextuality Pairs and 189 Trajectory Tables on this site aren't a list of clever connections. Each one has been validated against this methodology — which is how we can claim, plausibly, that the patterns we surface really were embedded in the text by the biblical authors themselves.
The NT authors aren't twisting OT meaning. They're following a method. That method has a name and a structure. Schnittjer & Harmon spell it out as seven specific choices. Reading the Bible's use of the Bible competently means making the same choices, in the same order, with the same caution.
You don't have to do this in detail every time you read. But knowing it's there — and knowing this site's cross-references operate on it — means that when Matthew says Isaiah was talking about Jesus, you can trust that he has reasons.
