Short answer. Partly, but the popular version is wrong in both directions, so here is the careful one. Isaiah 7:14 in Hebrew uses the word almah, which means a young woman of marriageable age, not the specific Hebrew word for virgin, bethulah. So the emphatic "virgin" is not simply sitting in the Hebrew. But the virgin reading is also not a Christian invention: the Jewish translators of the Greek Septuagint, more than two centuries before Jesus, rendered almah as parthenos, "virgin." Matthew later quoted that Greek version (Matthew 1:23). And in its original setting the verse was an eighth-century-BCE sign to King Ahaz about a child born in his own lifetime, not, at first, a prediction about a birth seven hundred years later. So it is neither a plain prophecy of a virgin-born messiah nor a simple mistranslation. It is a "young woman" verse that an ancient Jewish translation read as "virgin," which a Gospel writer then applied to Jesus.
What Isaiah 7:14 says in Hebrew
The Hebrew word at the center of everything is almah. It denotes a young woman of marriageable age, and it always refers to an unmarried one, who in that culture would ordinarily be presumed a virgin. But the word's core meaning is her youth and unmarried status, not a technical statement about her sexual history. Hebrew did have a word that leans more directly toward "virgin," bethulah, and Isaiah did not use it. That omission is the whole debate in miniature. Honesty requires the counter-point too: bethulah is not perfectly unambiguous either, since in a few places it needs a qualifier to make virginity explicit and can describe a betrothed or bereaved woman (Joel 1:8). So one cannot say Isaiah "avoided the clear word for a vague one." The accurate, narrow statement is this: the term in Isaiah 7:14 primarily means "young woman," and the forceful "virgin" is a reading laid on top of it, not the first thing the Hebrew says.
The original context: a sign to King Ahaz
Lift the verse back into its chapter and the messianic haze burns off. Isaiah 7 is set during the Syro-Ephraimite crisis around 734 BCE, when King Ahaz of Judah is terrified because two neighboring kings, Rezin of Aram and Pekah of Israel, have allied against him. Isaiah comes to steady him and offers a sign: a young woman will conceive and bear a son and call him Immanuel, "God with us," and before that child is old enough to tell right from wrong, the lands of the two kings Ahaz fears will be laid waste (Isaiah 7:15-16). The child is a living clock. His growth measures a near-term political deliverance for eighth-century Judah, and the very next chapter offers a parallel sign-child, born to the prophetess and named Maher-shalal-hash-baz, on the same "before the boy can speak" timetable (Isaiah 8:1-4). In its own world the Immanuel of Isaiah 7 is a child of Isaiah's own day, not a figure of the distant future.
The Septuagint chose "virgin," and it was Jewish
Here is the fact that dismantles the lazy skeptical meme. The strong "virgin" reading does not begin with Christians. Around the third to second century BCE, Jewish scholars translating Isaiah into Greek, the Septuagint, rendered almah with the Greek word parthenos, which carries a much stronger sense of "virgin." That translation choice was made more than two hundred years before Jesus was born, by Jews, for Jews, with no Christian agenda possible. Whether those translators intended full sexual virginity or simply reached for a normal Greek word for a young unmarried woman (parthenos can occasionally mean that too) is debated, but they did select the more virginity-loaded term. So the "virgin" in the virgin birth has an ancient and Jewish pedigree. It is an interpretive move inside the transmission of Israel's own scriptures, not a Christian error smuggled in at the last minute.
Matthew builds the virgin birth on the Greek
The New Testament then does what first-century interpreters routinely did: it reads an old text forward. Matthew 1:22-23 quotes Isaiah 7:14 in its Greek, parthenos form and presents the birth of Jesus to the virgin Mary as its fulfillment. Two things are true at once here, and honesty holds both. Matthew is working from the Greek, not the Hebrew, and he is reading the verse messianically and long-range, which is not what the verse meant in Ahaz's crisis. That is a fulfillment hermeneutic, the standard first-century practice of finding new, deeper reference in ancient scripture, rather than a claim about Isaiah's original intent. And separately, the virgin birth as a narrative does not stand only on this proof-text: Luke tells an independent birth story with the same claim (Luke 1:34-35) and never leans on Isaiah 7:14 at all. The doctrine and the proof-text are linked, but they are not the same thing.
The honest part
Tier it, and watch it correct both camps. Bedrock: the Hebrew of Isaiah 7:14 uses a word whose primary meaning is "young woman," not the most specific term for virgin, and the verse's first context is an eighth-century sign to Ahaz about a near-term birth. Also bedrock, and usually left out by the skeptics: the "virgin" reading is not a Christian mistranslation but a pre-Christian Jewish rendering in the Septuagint, which Matthew then used. Contested: exactly how much virginity almah and parthenos each imply, and how deliberate the Septuagint's choice was. And what none of this decides, against the apologists' fear and the skeptics' hope alike: whether the virgin birth actually happened. That question rests on the Gospel infancy narratives of Matthew and Luke, on history and theology, not on one Hebrew noun. The mature conclusion is the unglamorous one that annoys everybody: it is not a clean prophecy and it is not a clean mistake. It is a young-woman verse, read as "virgin" by ancient Jews in Greek, applied to Jesus by a Gospel writer, and the doctrine lives or dies elsewhere.
Common questions
Does Isaiah 7:14 say "virgin" or "young woman"?
In Hebrew it says almah, "young woman" of marriageable age. The specific Hebrew word most associated with virginity is bethulah, which Isaiah did not use. The strong "virgin" reading comes from the Greek Septuagint, which translated almah with parthenos, "virgin." So the Hebrew says young woman; the Greek says virgin.
Was the virgin birth a mistranslation?
Not a simple error. The Hebrew almah means "young woman," so the emphatic virgin sense does depend on the Greek. But that Greek reading (parthenos) was chosen by Jewish translators of the Septuagint more than two centuries before Christianity, not invented by Christians. It is better described as an ancient interpretive rendering than a mistake.
What does the Hebrew word almah mean?
It means a young woman of marriageable age who is unmarried, and who in that culture would normally be presumed a virgin. Its core meaning is her youth and unmarried status rather than a technical statement about virginity. Hebrew had other words that specify virginity more directly.
Who is the child in Isaiah 7:14 originally about?
A sign-child named Immanuel, given to King Ahaz of Judah during the Syro-Ephraimite crisis around 734 BCE. Before the child grew up, Isaiah said, the two kings threatening Judah would be gone (Isaiah 7:15-16). In its original context it is a near-term prophecy about eighth-century politics, not a distant prediction.
Did Jewish translators really render it "virgin" before Christianity?
Yes. The Septuagint, the Greek translation of the Hebrew scriptures made by Jews in roughly the third to second century BCE, used parthenos ("virgin") at Isaiah 7:14, over two hundred years before Jesus. The virgin reading is therefore pre-Christian and Jewish in origin, whatever the translators precisely intended.
Does this mean the virgin birth is false?
No. Whether the virgin birth happened is a separate question that rests on the Gospel infancy narratives of Matthew and Luke, not on the wording of Isaiah 7:14. The point here is narrower: the Hebrew verse says "young woman," the "virgin" comes from the ancient Greek, and the doctrine does not stand or fall on that single proof-text.
This page settles a word, not a birth. Whatever you conclude about Mary, conclude it from the Gospels that tell her story, not from a single Hebrew noun that means "young woman" and a Greek translation that made it "virgin" three centuries before anyone argued about it. The honest reading here is the one that leaves both the debunker and the apologist slightly unsatisfied, which is usually the sign it is right.
