Why Do Old Testament Quotations Sometimes Look Different in the New Testament?

You follow a New Testament footnote back to the Old Testament, expecting the same sentence. Instead, a word changes, a phrase disappears, or the quotation seems to make a different point. Hebrews mentions a body where your Psalm mentions ears. Paul describes a descent where Deuteronomy describes a sea crossing. Those are real differences worth investigating.

Old Testament quotations can look different in the New Testament because of English translation choices, different ancient textual forms, selective quotation, and deliberate interpretation. These explanations sometimes work together, but none explains every passage. The useful question is which explanation fits this particular quotation and what evidence supports it.

Separate Four Kinds of Difference

Before deciding that an author misquoted Scripture, identify what has changed:

• English wording: Translators may express related Hebrew and Greek phrases differently.
• Ancient source text: The New Testament writer may use a Greek form that differs from the Hebrew text underlying your Old Testament.
• Quotation form: A writer may shorten a passage, select particular clauses, or connect several scriptural passages.
• Interpretive use: A writer may explain, adapt, or apply earlier Scripture within a new argument.

These categories describe different questions. A translation decision concerns how words become English. A textual question concerns which ancient wording stands behind them. An interpretive question concerns what an author does with that wording.

Keep those questions separate long enough to investigate them. Calling every difference a paraphrase can conceal manuscript evidence. Calling every difference a textual variant can conceal an author’s visible explanation. Both shortcuts make the Bible harder to read accurately.

First Compare the Passages in the Same Translation

An English Bible normally translates its Old Testament and New Testament from different source languages. The quotation in Hebrews is translated from Greek, even when the quoted Psalm is translated from Hebrew. The translators are not simply copying their English Psalm into Hebrews.

The ESV’s published preface identifies its principal Hebrew and Greek editions and explains when other witnesses inform its decisions. Consulting a translation’s preface can therefore answer a question that comparing English sentences alone cannot.

Begin with both passages in one version. Then compare a second version and read the notes. If the mismatch disappears, English wording may explain it. If both versions preserve the same substantial difference, investigate the ancient texts and the author’s argument.

Avoid choosing whichever version makes the quotation look tidiest. A translation can serve readers by preserving a difference rather than silently harmonizing it. For the broader distinction between textual basis and translation method, see Bible Translations Explained.

Hebrew and Greek Scripture Have Their Own Textual Histories

The Masoretic Text is the Hebrew textual tradition underlying many modern Old Testaments. The Septuagint, often abbreviated LXX, is a collection of ancient Greek scriptural texts, many translated from Hebrew. It is useful background for New Testament quotation, but treating it as one uniform translation creates problems.

Different books have different translation characteristics. Greek copies also developed textual differences. The introduction to the New English Translation of the Septuagint, or NETS, specifically warns against imagining a uniform collection. A modern Septuagint edition also involves editorial decisions about which readings to print.

Consequently, finding a New Testament quotation unlike the Hebrew does not establish that its author invented the difference. Yet finding a similar Greek reading does not, by itself, establish exactly which copy the author used.

Sometimes a Greek translation may preserve evidence for a different Hebrew source. Sometimes the difference arose through translation or within Greek transmission. Each proposal requires passage-specific evidence. Greek is not automatically correct because a New Testament writer uses it; Hebrew is not automatically corrupt because a quotation differs.

For the wider manuscript history, see How Did We Get the Bible?. Here, the narrower task is tracing a particular quotation through the evidence available for it.

Recognize Quotation Alongside Explanation

A biblical writer can quote Scripture while also explaining it. Modern quotation marks and parentheses help English readers follow that movement, but they are editorial presentation, not an ancient manuscript’s modern punctuation system.

Read the introductory formula and the sentences that follow. Is the writer identifying a speaker, drawing a conclusion, connecting passages, or supplying an explanation? Do not assume every word in a printed quotation block belongs to a continuous sentence in the earlier passage.

This also calls for restraint. An omission may reflect selective citation, but it does not prove quotation from memory. A change that suits an argument may be deliberate, but suitability alone does not prove who introduced it. The surviving text and our reconstruction of its history are different kinds of evidence.

Worked Comparison One: Psalm 40 and Hebrews 10

Read Psalm 40:6–8 alongside Hebrews 10:5–10. In the World English Bible (WEB), the Psalm says “You have opened my ears,” while Hebrews says “you prepared a body for me.” These are not merely two English synonyms. For an additional comparison, the ESV’s Psalm footnote explains that the Hebrew uses the image of digging ears.

First, locate the passage correctly. English Psalm 40:6 corresponds to Hebrew Psalm 40:7 and Greek Psalm 39:7. Different numbering can make a successful lookup look like a missing verse.

Second, check the Greek evidence carefully. The body reading appears in major Greek Psalm witnesses and agrees with Hebrews. Martin Karrer discusses that evidence, including Papyrus Bodmer XXIV, in The Epistle to the Hebrews and the Septuagint, pages 348–349.

There is an important complication: NETS Psalm 39:7 prints ears. Its Psalms translation is based primarily on Alfred Rahlfs’s edited Greek text. You can therefore open a reputable English translation of the Septuagint and still find a difference from Hebrews.

Why did the readings diverge? Scholars have proposed an interpretive rendering of the Hebrew image, a change during Greek copying, or influence from Hebrews on later Psalm transmission. Karrer argues for the body reading as the earlier Greek form and challenges competing reconstructions. Reporting that argument is different from claiming the entire history is settled. The attestation of a reading is firmer evidence than a proposed account of its origin.

Third, read the argument. The Psalm connects worship with willingness to do God’s will. Hebrews presents the quoted words as Christ’s speech and develops them toward his bodily offering in 10:10. The body wording matters within that argument, alongside the wider discussion of sacrifice and God’s will. Benjamin Ribbens’s study of Psalm 40 in Hebrews especially emphasizes the offering Hebrews identifies, cautioning against reducing the passage to obedience alone.

What we can conclude: Hebrews’ wording has significant support in Greek Psalm transmission. That makes an accusation of careless invention premature. It does not make every detail of the earliest Greek wording or the author’s source recoverable with certainty.

Worked Comparison Two: Deuteronomy 30 and Romans 10

Read Deuteronomy 30:11–14 and Romans 10:6–10, then widen the comparison to Deuteronomy 30:1–10 and Romans 9:30–10:13. This case involves more than identifying another ancient translation.

In Deuteronomy, Moses tells Israel that God’s commandment is accessible. They do not need someone to travel to heaven or cross the sea to retrieve it. The passage ends with the commandment’s nearness and the call to carry it out. Its surrounding context includes return to God, restoration, and God’s work on the people’s hearts.

Romans uses that recognizable pattern but changes its application. Deuteronomy describes something “beyond the sea”; Romans asks about descending “into the abyss” (WEB). Paul explicitly connects the ascent and descent with Christ. He then connects the near word with the message being proclaimed, followed by confession and belief in verses 9–10.

Checking Greek Deuteronomy does not remove that difference: NETS Deuteronomy 30:11–14 also describes the sea crossing. The change cannot simply be explained by saying Paul followed the Septuagint instead of the Hebrew.

Notice the repeated “that is” in Romans (WEB). Paul marks interpretive explanations within his use of the passage. These references to Christ are visible parts of his argument, rather than English translators secretly adding Christian meaning to Deuteronomy. The United Bible Societies translation handbook distinguishes the original reference to the Law from Paul’s Christ-focused use and discusses the changed journey imagery.

Interpreters disagree about precisely how Paul understands the relationship between Deuteronomy and his gospel. Douglas Mohrmann’s study of Romans 10:6–8 surveys competing explanations before developing its own. Reading the wider contexts helps evaluate those explanations without pretending that one short comparison settles the debate.

What we can conclude: Paul selects, adapts, and explains scriptural language in a Christ-focused argument. We can observe those actions directly. Reconstructing every theological or literary reason behind them requires further interpretation.

What a Wording Difference Can and Cannot Establish

The two examples should prevent a universal answer. Psalm 40 requires attention to Greek textual history. Romans 10 visibly combines scriptural language with interpretive explanation. Both require reading the surrounding argument.

A wording difference alone does not establish deception, doctrinal corruption, or incompetence. Neither does identifying an ancient quotation practice automatically demonstrate that an interpretation is persuasive. Fair criticism asks what textual form was available, what claim the author makes, and how the cited passage functions.

Christian readers can understand these uses as part of the apostles’ witness to Christ while still investigating their wording honestly. Jewish and other readers may recognize the textual relationship without accepting the Christian conclusion. Describe that disagreement accurately rather than pretending textual comparison forces everyone to share a theology.

The same distinction matters in apologetics. Showing how Hebrews interprets a Psalm establishes something about Hebrews’ theological reading. It is not independent historical proof of the events or claims that reading presupposes. Historical arguments need evidence suited to the historical question.

Comparing Bible Quotations: read both passages; compare the wording; check the evidence. Teaching summary, not a quotation of Scripture.

Use This Worksheet for Any Old Testament Quotation

Choose one quotation and complete these six entries before building an argument on it:

1. Exact citation: Record the New Testament reference and the proposed Old Testament source. Check whether the footnote identifies several passages or a different numbering system.
2. Full passages: Read the complete paragraph, poem, or speech in both books. Summarize each passage’s concern in one sentence before comparing individual words.
3. Translation and wording: Name your English version and record the specific difference. Check another version and distinguish a changed word from an omitted clause or added explanation.
4. Textual basis: Read the translation notes and preface. If Greek Scripture is relevant, identify the Septuagint edition or translation you consulted. Record whether it actually accounts for the difference.
5. Commentary and alternatives: Consult a commentary that discusses the New Testament’s use of the Old Testament. Ask whether its conclusion rests on manuscript evidence, translation analysis, contextual interpretation, or a combination.
6. Confidence and limits: State what is observable, what is probable, and what remains disputed. Write the narrowest conclusion the evidence supports.

For Psalm 40, a responsible final entry distinguishes strong evidence for the body reading in Greek transmission from uncertainty about its earliest development. For Romans 10, it distinguishes Paul’s explicit explanations from disputed accounts of his interpretive method.

If a resource merely announces that the author quoted loosely, ask it to show the comparison. Good explanations make the evidence easier to inspect.

Frequently Asked Questions

Did New Testament writers always quote the Septuagint?

No. Greek Scripture is an important source, but quotations do not all follow one uniform Greek edition. Some involve other textual forms, selection, adaptation, or combinations of passages. Identify the evidence for the individual quotation.

Does different wording mean the Old Testament was changed?

Not necessarily. The difference may involve English translation, an ancient Greek rendering, textual variation, or interpretation. A New Testament quotation does not by itself establish when a difference arose or which reading is earliest.

Why do some Septuagint translations still differ from the New Testament?

They may translate different Greek readings, follow different editorial decisions, or preserve a source passage that the New Testament writer adapts. Psalm 39 in NETS illustrates why naming the edition matters.

What should I do when I cannot resolve a quotation?

Record the exact issue and consult a specialist commentary. Keep the secure findings separate from the unresolved ones. You can understand much of an author’s argument without claiming certainty about every stage of the text’s history.

Sources and translation note:

The linked biblical texts allow readers to inspect the comparisons. NETS supplies an English translation of edited Greek texts, not a transcript of every ancient Greek manuscript. Karrer, Ribbens, Mohrmann, and the UBS handbook offer scholarly arguments with different purposes; their interpretations should not be treated as interchangeable or unanimous.
