Matthew 1:23 — The virgin birth
Matthew grounds the virgin birth in the Greek παρθένος (“virgin”). The Hebrew ‘almah means simply “young woman,” so the specifically virginal reading comes through the Septuagint.
When the New Testament quotes the Old Testament, it most often follows the Greek Septuagint (LXX) — the Bible of the early church — rather than the Hebrew Masoretic Text. Here are the clearest cases, side by side, each linked to the Greek text.
The apostles wrote in Greek to a Greek-speaking world, and the Scriptures they carried were the Septuagint. In dozens of quotations the argument only works from the Greek: Matthew’s “virgin,” the “body” prepared for Christ in Hebrews, the inclusion of the Gentiles in Acts 15. Some Septuagint readings once thought to be loose translation are now confirmed by the Dead Sea Scrolls. Each row below links to that verse in the Septuagint so you can read the Greek yourself.
Matthew grounds the virgin birth in the Greek παρθένος (“virgin”). The Hebrew ‘almah means simply “young woman,” so the specifically virginal reading comes through the Septuagint.
Hebrews’ argument that Christ came to offer his body follows a Greek reading “σῶμα” (a body); the Septuagint tradition itself splits between “a body” and “ears you prepared” (shown here), while the Hebrew reads “ears you have opened.” (LXX Psalm 39:7.)
James’ Jerusalem-council argument for including the Gentiles follows the LXX (“the rest of mankind seek the Lord”), not the Hebrew (“possess the remnant of Edom”).
Hebrews quotes a line found in the Septuagint (and confirmed at Qumran) that the Masoretic Text does not contain at all.
Matthew’s Gentile-hope conclusion tracks the Greek (“in his name the nations will hope”) rather than the Hebrew (“the coastlands wait for his torah”).
Paul’s “their voice has gone into all the earth” follows the LXX φθόγγος (“sound”), where the Hebrew reads “their line.” (LXX Psalm 18:5.)
Hebrews has Jacob worship “on the top of his staff” (LXX, reading מַטֶּה), where the vowel-pointed Hebrew reads “the head of the bed.”
Both Paul and Peter cite “whoever believes will not be put to shame,” following the LXX rendering of a Hebrew verb the MT reads as “make haste.”
Hebrews applies Psalm 22 to Christ using the Septuagint’s Greek wording (LXX Psalm 21:23).
Jesus reads Isaiah in the synagogue following the LXX’s “recovery of sight to the blind,” a phrase not in the Hebrew of Isaiah 61.
Jesus’ rebuke of the Pharisees follows the LXX (“teaching human precepts as doctrines”), which sharpens the Hebrew clause.
Paul’s climactic Gentile-hope citation uses the LXX’s “the nations will hope in him.”
Paul’s resurrection taunt draws on the Septuagint’s question form of Hosea 13:14.
Hebrews’ “he scourges every son whom he receives” follows the LXX of Proverbs 3:12.
Both James and Peter cite the LXX form: “God opposes the proud but gives grace to the humble.”
The Ethiopian eunuch is reading Isaiah 53 in the Septuagint when Philip explains it of Christ.
Hebrews follows the LXX of Habakkuk 2:3–4, including the “if he shrinks back” clause absent from the Hebrew word order.
Paul’s “the name of God is blasphemed among the Gentiles because of you” matches the LXX expansion of Isaiah 52:5.
Paul’s “now is the acceptable time” draws its key word δεκτός from the Septuagint of Isaiah 49:8.
Jesus’ reply to the chief priests uses the LXX “you have prepared praise,” where the Hebrew reads “you have established strength.” (LXX Psalm 8:3.)
Hebrews takes Psalm 104:4 as a statement about angels, following the LXX word order (LXX Psalm 103:4).
Peter’s “if the righteous is scarcely saved” follows the Septuagint of Proverbs 11:31.
Yes. Most Old Testament quotations in the New Testament follow the Greek Septuagint (LXX) rather than the Hebrew, because Greek was the common language of the first-century church. In dozens of places the wording only makes the New Testament author's point when read from the Septuagint.
Well-known examples include Matthew 1:23 (the "virgin" of Isaiah 7:14), Hebrews 10:5 ("a body you prepared" from Psalm 40:6), Acts 15:16-17 (Amos 9:11-12), and Hebrews 1:6 (a line of Deuteronomy 32:43 missing from the Masoretic Text). This page lists the clearest cases side by side.
The Septuagint was translated from Hebrew manuscripts centuries before the Masoretic Text was standardized, and its translators sometimes read or rendered the Hebrew differently. Some Septuagint readings are now confirmed by the Dead Sea Scrolls, showing they reflect an ancient Hebrew text.
