Matthew and Mark both quote Isaiah at the Jordan, and both stop at the end of Isaiah 40:3. Luke keeps reading. He carries the citation through 40:4 and 40:5 and stops on four words: the salvation of God. Screened against 30,637 units of the Greek Old Testament, those three verses are the three deepest measurements in the chapter — 13, 11 and 8 words, each with a tie band of one. Then the chapter ends with seventy-six names, and one of them is a man the Hebrew Genesis does not have. This study measures both ends, prints its own counter-examples, and says plainly what it could not check. See the method →
Luke 3:1–38 (selections)
Greek NT · ESVThe Shape of the Passage
Frame (inclusio) around a sequenceWho wrote this, to whom, and why does the chapter open with a Roman date and end with a list of dead men?
Author
Luke — the physician, Paul’s companion (Col 4:14), writing the first of two volumes for Theophilus and promising an “orderly account” (Luke 1:1–4). Chapter 3 is where that promise is cashed. He is the only evangelist who dates the gospel by a synchronism of named rulers — a fifteenth regnal year, a governor, three tetrarchs and a high priesthood — and the only one who carries Isaiah’s wilderness citation past its first verse. Matthew and Mark stop at Isaiah 40:3. Luke goes on through 40:4 and 40:5, and stops on the words the salvation of God.
Why that matters for reading him. Those four words are not a flourish. They come back once, in the last speech of Acts, and nowhere else in the New Testament. Whatever else Luke is doing in chapter 3, he is planting the sentence his second volume will close on.
Audience
Theophilus and a largely Gentile readership — readers for whom a Roman consular-style date is orientation rather than decoration, and for whom “all flesh” is not a throwaway. Luke’s genealogy does not stop at Abraham the way Matthew’s does. It keeps going — past Abraham, past Noah, past Adam — and ends at God. A reader with no Jewish ancestry is inside that list from the second line.
How they would have heard the three questions. Crowds, tax collectors and soldiers all ask the same thing, and John never tells one of them to change his profession. He tells each of them what to do with what is not theirs. The repentance Luke reports is auditable.

A Roman date, a desert preacher, and what an ancient genealogy was for.
Read the chapter against how the ancient world dated events and used ancestor lists — and against the Jewish movements that were also baptising in water.
Which parallels shed light on religion and worldview?
Dating by rulers. Luke’s six-fold synchronism is the standard ancient way of fixing a year — Thucydides does it, and so does Jeremiah 1:1–3 and Ezekiel 1:1–3. The form itself is a prophetic-book opening, and Luke uses it to introduce a prophet.
Genealogy as argument. In the ancient Mediterranean a family list was not an archive record; it was a claim — to land, to priesthood, to a throne, to a people. That is why Matthew’s runs to Abraham and David and Luke’s runs to Adam. They are making different claims, not correcting each other’s data.
- Josephus, Life 1–6 — a first-century Jew opening his autobiography by reciting his priestly descent from public registers: what genealogies were for.
- Josephus, Antiquities 18.116–119 — John the Baptist as a historical figure, executed by Herod Antipas: an outside witness to the man Luke dates.
- 1QS (Community Rule) III–V — a Judaean group practising repeated washings tied to repentance and the Spirit. A parallel, not a source, and not Scripture on this shelf; John’s baptism is once, public, and for outsiders.
- Jubilees 8:1–5 — a Second-Temple retelling that also knows a Kainan between Arphaxad and Shelah. Not consulted in the original for this page and not Scripture here; noted because it shows the extra name was not unique to one Greek manuscript tradition.
Luke 3 begins with the most powerful men alive and ends with a list of the dead. The first list is short, current, and famous; the second is long, obscure, and finished. Both are ways of saying where a person comes from, and Luke lets them face each other across one chapter. Tiberius Caesar is at the top of the world and is not in the genealogy. Cainan is a name nobody can tell you a story about, and he is.
Six words, each of which can be counted.
Every count in this section came from a search of the corpora on this disk, not from a concordance entry quoted at second hand. Where a count is of the local Greek Old Testament rather than of the whole Septuagint tradition, it says so.
“Salvation” — the substantivised neuter. The form σωτήριον occurs three times in the whole Greek New Testament and all three are Luke’s (2:30, 3:6, Acts 28:28); the word stands once more in the genitive at Ephesians 6:17, so the lexicon count is four. Its presence in Isaiah 40:5 is a feature of the Greek text; the Hebrew there has no noun for salvation at all.
“The word of God” — the prophetic call-formula with one word changed. Our Greek Old Testament has ἐγένετο λόγος κυρίου 85 times and ἐγένετο ῥῆμα κυρίου 5 times; Luke writes ῥῆμα θεοῦ, which is zero hits there and one hit in the New Testament.
“Release, forgiveness” — the jubilee word of Leviticus 25, and the New Testament’s word for the forgiveness of sins. Five of the seven occurrences of the accusative ἄφεσιν ἁμαρτιῶν are Luke’s — and adding the other cases (Luke 1:77, Acts 13:38) makes it seven of nine.
“What shall we do?” — eight occurrences in the Greek New Testament, three of them in five verses here, and the closest fourth is the crowd at Pentecost (Acts 2:37).
“As was supposed” — a two-word parenthesis that qualifies the whole list before it begins. Luke does not withdraw the genealogy; he tells you where its first link is not what it appears.
“Cainan” — two occurrences in the Greek New Testament, both here. The second (Enosh’s son) is in every text; the first (Arphaxad’s son) is in the Greek Genesis and not in the Hebrew one.
How this chapter handles the Old Testament:
Luke 3 quotes the Old Testament once, and says so: “as it is written in the book of the words of Isaiah the prophet.” That single citation runs 13, then 11, then 8 words deep across three verses, each with a tie band of 1 — the three deepest measurements in the chapter against the Greek Old Testament, and they are consecutive. Everything else in the chapter that sounds like the Old Testament measures 5 or less, and the deepest of those are two runs of five — Abraham’s servant talking to Laban, and Isaac feeling for a son in the dark. Prophetic diction is not quotation, and the numbers here separate the two cleanly.
The screens, both directions, with the distributions printed.
Two exhaustive screens. Every one of the 38 verses of Luke 3 against 30,637 verse units of the Greek Old Testament held here; and every one of them against the other 7,889 verses of the Greek New Testament. Runs are contiguous whole word forms, never lemmas. Nothing was sampled.
Screen 1 — Luke 3 against the Greek Old Testament:
Across the 38 rows: 35 reach two, 24 reach three, 12 reach four, 5 reach five, 3 reach eight, 2 reach eleven, 1 reaches thirteen, and nothing reaches fourteen.
- 3:4 → Greek Isaiah 40:3 — run 13, tie band 1. The deepest in the chapter.
- 3:5 → Greek Isaiah 40:4 — run 11, tie band 1.
- 3:6 → Greek Isaiah 40:5 — run 8, tie band 1. Three consecutive verses hold the top three places, and no other row in the chapter reaches even six.
- 3:13 → Greek Genesis 24:56 — run 5, tie band 1. A narrative formula and nothing more. The band is 1 and the finding is still zero.
- 3:22 → Greek Genesis 27:21 and 27:24 — run 5, tie band 2. Isaac to Jacob. The deepest contact the voice at the baptism has with the Greek Old Testament is an accident.
- 3:17 → run 4, tie band 38. ἐν τῇ χειρὶ αὐτοῦ. The band is the whole story.
- 3:27 → 1 Esdras 5:5 — run 4, tie band 1. τοῦ Ζοροβαβὲλ τοῦ Σαλαθιήλ. The deepest measurement anywhere in the genealogy is four words, and it lands on a book outside the Hebrew canon. It proves nothing except that two names in a row is as much contact as a name-list can generate.
Screen 2 — Luke 3 against the rest of the Greek New Testament:
Across the 38 rows: 31 reach two, 23 reach three, 17 reach four, 9 reach five, 8 reach six, 7 reach seven, 6 reach eight, 5 reach ten, 3 reach fourteen, 2 reach twenty, 1 reaches twenty-two, and nothing reaches twenty-three.
- 3:8 → Matthew 3:9 — run 22, band 1. 3:9 → Matthew 3:10 — run 20, band 1. 3:7 → Matthew 3:7 — run 10, band 1.
- 3:4 → Matthew 3:3 and Mark 1:3 — run 14, band 2. One word deeper than any of the three reaches into Greek Isaiah.
- 3:22 → Mark 1:11 — run 10, band 1. 3:16 → Matthew 3:11 — run 8, band 1. 3:3 → Mark 1:4 — run 6, band 1.
- 3:6 → Acts 28:28 — run 4, band 1. A short run, and the shortness is the point: the two verses share exactly τὸ σωτήριον τοῦ θεοῦ and nothing around it. Those four words occur in no other verse of the Greek New Testament.
- 3:5 → Revelation 6:14 — run 4, band 1. Printed as a counter-example. A band of 1 on four ordinary words is not a connection, and this page will not treat one as a connection anywhere else either.
At the top: Luke alone carries the Isaiah citation to 40:5, and the phrase he lands on — τὸ σωτήριον τοῦ θεοῦ — stands in the Greek Isaiah where the Hebrew has an adverb. It returns once, at the end of Acts. At the bottom: Luke’s list runs 21 links from Adam to Abraham, which is what the Greek Genesis gives and one more than the Hebrew, because of Cainan. Two independent measurements, at the two ends of one chapter, pointing the same way. What that means about Luke’s Bible is a question this page raises and does not answer: we did not compare manuscripts, we have no apparatus, and we do not know what a first-century scroll of Isaiah or Genesis in Luke’s hands would have read.
What the scholarship says, and what this page could not check.
This is the section that keeps the shelf honest. It names the limits of the measurement before it names its results.

What this page did NOT check, and where it is weakest:
- No critical apparatus of any kind was consulted, for any text. Not for the Greek New Testament, not for the Greek Old Testament, not for the Hebrew. The Admin/Arni reading in Luke 3:33 is a live variant and the SBLGNT itself flags it; this page measured the SBLGNT and let the variant stand unadjudicated. Several editions of Luke read Ἀράμ there instead, which would make the list one name shorter.
- The Cainan question was checked on this disk only. That means: Rahlfs’ Septuaginta as digitised by CATSS, and the Masoretic text as digitised by Sefaria. We did not consult a Genesis manuscript, the Samaritan Pentateuch, the Qumran Genesis fragments, Jubilees in the original, or any Greek Genesis witness older than Rahlfs’ edition. The finding is that these two editions differ in a countable way, and that Luke agrees with one of them. It is not a finding about what any first-century scroll said.
- Greek 1 Chronicles is too short here to test. Our CATSS 1 Chronicles jumps from 1:17 to 1:24, so the stretch where a Cainan could have appeared in the Greek Chronicles is not in the file at all. Only the Hebrew side of that particular check could be run.
- 1QIsaa was not consulted. The Isaiah 40:5 point — that the Hebrew has an adverb where the Greek has ‘the salvation of God’ — was made against the Masoretic text alone. The great Isaiah scroll is exactly the witness that could complicate it, and we do not hold it.
- The runs cannot see allusion, and here that costs a lot. Psalm 2:7, Isaiah 42:1 and Genesis 22:2 all stand behind the voice at the baptism in the judgement of essentially every commentator, and they measure 2, 2 and 1. If this page reported only what the screen returns, it would have to report that the baptism has no Old Testament background, which would be false.
- Luke’s and Matthew’s genealogies are not harmonised here. Two Josephs, two fathers of Joseph, 41 generations against 26. The historic proposals — Luke gives Mary’s line; levirate marriage; legal against natural descent — are arguments, and this page has measured none of them. It reports the shape of the difference and stops.
- Direction of influence is never asserted. Nothing here says Luke used Matthew or Matthew used Luke or both used a third source; nothing says Luke read a Greek Isaiah or translated a Hebrew one; nothing says the Greek Genesis added a name or the Hebrew lost one. The runs are printed with their bands and the weighing is left to the reader.
From a desert preacher and a list of the dead, to today.
Name what you learned, why it matters, and one concrete response.
What should we carry away — and do?
- The gospel is dated. Luke pins it to a regnal year, a governor and a high priesthood, because it happened. You can be wrong about a claim that is anchored to a calendar; you cannot call it a myth.
- “All flesh.” The line Matthew and Mark did not reach is the line Luke stopped on, and it is the line his second volume ends on. The salvation of God was aimed past the fence from the first sermon.
- Repentance is auditable. Three groups asked the same question and got three answers about money, power and other people’s property. Not one of them was told to leave his job.
- Ancestry is not standing. “We have Abraham as our father” was true and useless. And the list that runs to Adam puts everyone reading this inside it.
Step in response: answer John’s question with a number. Pick the thing in your life that is closest to a second tunic and give it away this week — and then read Acts 28:28 out loud and notice that you are the person it is talking about.
Luke 3:6 · to share
Greek NT + ESVEvery Deep Research page traces its passage across the whole sweep — the Old Testament, the Second-Temple world between the testaments (historical witnesses, not Scripture), and the New Testament. Follow the thread:
Pleasant Springs Church — Deep Research
Research method after Michael S. Heiser’s Bible Research Method (examine dictionaries → ancient literature → important words → textual connections → academic publications → share), with the Pleasant Springs “Author & Audience” foundation. Scripture set in the Hebrew, the Greek editions named on each page and the ESV (Old Testament), and the Greek New Testament and the ESV (New Testament), per the practice of Pleasant Springs Church. Luke 3 research grounded in Green (NICNT), Bock (BECNT), Bovon (Hermeneia), Nolland (WBC) and Marshall (NIGTC), with Pao & Schnabel in Beale & Carson on the Old Testament use, and Marshall D. Johnson on the genealogies. Text: Greek New Testament from the SBL edition as digitised by MorphGNT; Greek Old Testament from Rahlfs’ Septuaginta as digitised by CATSS; Hebrew from Sefaria’s Miqra according to the Masorah. No critical apparatus of any kind was consulted, and no variant was adjudicated — including the flagged Admin/Arni reading at Luke 3:33, which several editions do not have. ⚠️ VERSE NUMBERING — Luke has NO offset. The SBLGNT and the English Bibles agree that Luke 3 has 38 verses, and every reference to Luke on this page is the same number in a Greek New Testament and in an ESV. The two sources quoted here are also aligned, and one of them only looks it: Isaiah runs chapter-for-chapter in Hebrew, Greek and English (the one seam in that book, at 63/64, is nowhere near chapter 40); and Genesis 11 has 32 verses in the Masoretic text and 32 in the Greek — but the Greek packs Cainan’s entire generation into its verse 13, so the same verse number holds different amounts of text on the two sides. Equal verse counts are not equal contents. ⚠️ The measurement, in full. Greek against Greek. MorphGNT field 6, the normalised word (the column that already resolves elision and the movable nu); CATSS FORM column (cols 0–24), beta-code transliterated first. Both sides lowercased, accents and breathings dropped, final sigma folded, then filtered to Greek letters — the same filter applied to both corpora. Contiguous runs of whole word FORMS, never lemmas: two forms of the same verb do not match. Corpus: the 38 SBLGNT verses of Luke 3 against 30,637 verse units across the 64 CATSS Greek Old Testament files held here, and separately against the other 7,889 verses of the Greek New Testament. Exhaustive and deterministic; nothing was sampled, so no seed applies. Small numbers on this page use the Greek-side convention (unigram_fallback=True): a reported run of 1 means the two verses share one word and no two consecutive words. ⚠️ The runs find verbatim contact, not allusion, and on this page that gap is wide. The deepest Greek Old Testament contact for the voice at the baptism is Isaac speaking to a disguised Jacob (Genesis 27:21, 24; run 5, band 2), while Psalm 2:7, Isaiah 42:1 and Genesis 22:2 — the texts every commentator names — measure 2, 2 and 1. Both facts are printed. Neither cancels the other. ⚠️ The Cainan finding is a finding about two printed editions on this disk. Rahlfs’ Greek Genesis has him at 10:22, 10:24, 11:12 and 11:13; the Masoretic Genesis does not, and neither does Masoretic 1 Chronicles 1:18 or 1:24. Our Greek 1 Chronicles is missing 1:18–23 entirely, so the Greek side of that check could not be run at all. No manuscript, no Qumran fragment, no Samaritan Pentateuch and no apparatus was consulted. The claim is that the two editions differ by one countable link and that Luke’s list matches one of them — nothing about what Luke read. ⚠️ Direction of influence is never asserted. Nothing here says who wrote first among the Synoptics, which text of Isaiah or Genesis stood in front of Luke, whether a name was added or lost, or whether any reading is early or late. Typology is handled per the house position: what the text says, what the New Testament itself draws, and what we see from this side of the cross — with the seeing left to the reader.
