Israel's God has a personal name. In the Hebrew Bible it is written with four consonants — יהוה, Yod–He–Waw–He, the Tetragrammaton (Greek for "four letters") — and it stands there some 6,800 times, from its self-disclosure at the burning bush ("I AM THAT I AM… the LORD God… this is my name for ever," Exodus 3:14–15) to the psalmist's "thou, whose name alone is JEHOVAH, art the most high over all the earth" (Psalm 83:18). Yet how that name is to be read, vocalized, and handled has been contested for well over two thousand years — and the two English forms most people know, Yahweh and Jehovah, are the endpoints of that long argument, not neutral spellings.
This page traces the story of the Name across time, earliest witness first: the Second-Temple reverence that stopped pronouncing it, reading Adonai ("Lord") aloud in its place (so the Septuagint's Kyrios and every "the LORD" of later Bibles); the Greek Fathers who nonetheless transcribed what they had heard — Clement's Jave, Origen's Iao, the Iabe of Epiphanius and Theodoret; Jerome, who calls the Name "unspeakable" and records how Greek scribes, leaving it in archaic Hebrew letters, produced the notorious misreading "ΠΙΠΙ"; the Masoretes, who fixed the consonantal text and pointed it with the vowels of the spoken substitute; the medieval readers who fused those borrowed vowels with the consonants to coin the hybrid "Jehovah"; Gesenius and the nineteenth-century Hebraists who argued the older sound was "Yahweh"; and the modern Sacred-Name and Jehovah's-Witness movements that make the form of the Name a matter of obedience. The "belief that developed" here is the church's whole practice-and-understanding of the Name — how to say it, whether to say it, and what turns on getting it right — not a single dogma.

The chronological witnesses are being added, earliest first; the five below run from the earliest Christian transcriptions to the fifth-century reports of how the Name was actually spoken. Still to come are the Second-Temple avoidance and Septuagint Kyrios-substitution that precede them, the Masoretic pointing, the medieval "Jehovah," Gesenius's "Yahweh," the KJV/ASV, and the modern Sacred-Name and Jehovah's-Witness movements. The Name's earliest extrabiblical attestation (the Egyptian "Shasu of yhw" at Soleb) and the disputed reading of a second Yahweh figure are weighed under Arguments below.
Clement of Alexandria gives one of the earliest Christian transcriptions: the "mystic name of four letters" affixed to the high priest and the innermost sanctuary "is called Jave, which is interpreted, 'Who is and shall be'" — a two-syllable Greek rendering close to the modern "Yahweh," glossed by the self-naming of God at the burning bush.1
Origen, refuting the Gnostic sorcerers who traded on potent-sounding names, reports the Hebrew forms of the Name — Iao, Jah, Sabaoth, Adonai — and insists that these, drawn "from the Hebrew Scriptures," are "names of one and the same God," not the several deities the magicians imagined; the passage doubles as evidence of how the Name was written and spoken in the Greek-speaking church and its magical fringe (that fringe — the survival of Iao, Sabaoth, and Adonai as voces magicae in the Greek Magical Papyri — is weighed on the Name in the Greek Magical Papyri).2 In his notes on Psalm 2 he adds the textual observation at the root of the whole later confusion: in "the more accurate exemplars" the Name is written not in Greek but in Hebrew characters, "not, however, in the current script, but in the most ancient" — the archaic paleo-Hebrew letters whose resemblance to the Greek capitals Π-Ι-Π-Ι bred the "Pipi" misreading Jerome would record.3
Epiphanius of Salamis, running through the Hebrew names of God in his heresy-catalogue against the Gnostic Archontics, renders the Tetragrammaton in Greek as Ἰαβέ (Iabe) — which his modern translator gives as "Jahveh" — and glosses it "He who was and is, He who forever is," tying it to the burning-bush self-naming; the two-syllable ya-be he reports, not the later three-syllable "Jehovah," is what he takes the Name's sound to be.4
Jerome, listing the ten Hebrew names of God for Marcella, calls the Tetragrammaton "unspeakable" (ἀνεκφώνητον) and records the celebrated blunder by which Greek readers, mistaking the Hebrew letters left in the text for the visually similar Greek ones, read the Name aloud as ΠΙΠΙ ("Pipi") — the classic proof that its true sound was already being lost and that leaving it in archaic Hebrew script inside a Greek book actively bred misreadings.5
Theodoret of Cyrus gives the single most-cited patristic report of the living pronunciation: answering a question on the Name revealed to Moses, he states that the Samaritans say it Ἰαβέ (Iabe) while the Jews say Ἀϊά (Aïa — the "I AM" of Exodus 3:14, not the Tetragrammaton itself). The Samaritan two-syllable ya-be, from the one community that never adopted the taboo on speaking the Name, is the chief external support for the modern "Yahweh" — though Theodoret wrote centuries after the Name had left common Jewish speech, worked from the Greek and Syriac rather than the Hebrew, and may here depend on Epiphanius.6
The off-timeline sub-claims about the Name — whether it should be spoken at all, how it was vocalized, its earliest attestation, its pronunciation, and the "second Yahweh" reading — are being worked as argument pages. Two rival pairs are weighed together first: whether to speak the Name or reverently avoid it, and how the four consonants were to be read (Yahweh or Jehovah); then a standalone claim — whether the New Testament autographs themselves contained the Name; several further sub-claims are already weighed on adjacent timelines and are linked below:
Before the argument over how the Name was to be read came a deeper one over whether it was to be spoken at all. The Second-Temple reverence that stopped pronouncing יהוה, reading Adonai ("Lord") in its place — from which the Septuagint's Kyrios and every "the LORD" of later Bibles descend — is met in the modern period by the Sacred-Name and Jehovah's-Witness movements, which hold the Name should be restored to speech. The two are weighed as a pair, with the historical practice kept carefully apart from the normative "must" on either side.
That reverent non-pronunciation — reading Adonai / ha-Shem for the Name — is the older and dominant Jewish practice is sound: it rests on converging evidence (the Mishnah reserving the spoken Name to the high priest on the Day of Atonement; the blasphemy law of m. Sanhedrin turning on pronouncing it; Josephus' refusal; the Qumran paleo-Hebrew script and tetrapuncta; the Septuagint's blanket Kyrios). The normative step — that the Name therefore must not be spoken — is contested: it leans on the weaker "pronounce" sense of naqab in Leviticus 24:16 and is a Second-Temple development, not the Bible's own free use of the Name.
The restorationist point that the Name is a genuine personal name, given "for ever" as a memorial (Exodus 3:15; Psalm 83:18) and effaced by translating it "the LORD," is well-grounded. But the normative thesis of the Sacred-Name and Jehovah's-Witness movements — that it must be restored to speech — is genuinely disputed: it runs against a reverence-substitution Scripture's "memorial for ever" does not clearly forbid, against a New Testament that never restores the Name in its surviving Greek text, and (for the Witnesses) against the fact that "Jehovah" is itself the late hybrid form.
The two English forms everyone knows, Yahweh and Jehovah, are the endpoints of the same long argument over how the four consonants were to be read. They are best weighed as a pair, because the same body of evidence — the two-syllable transcriptions of the Greek Fathers, the Masoretic pointing, the theophoric names — bears on both, and the findings dovetail: what makes "Yahweh" a probable reconstruction is exactly what makes "Jehovah" impossible as a genuine ancient word.
The pointed יְהֹוָה carries the vowels of the spoken substitute Adonai, not the Name's own; splice those borrowed vowels to the consonants YHWH and you get the impossible hybrid "Jehovah" — a form absent from antiquity and first current among medieval and early-modern Christian Hebraists (Martini c. 1270, popularized by Galatinus, 1518). Two trims: the vowels are the surrogate's adapted, not copied exactly, and Galatinus popularized rather than coined the form; and the verdict rates the form's origin, not the propriety of continuing to use it.
The two-syllable Yahwe(h), first syllable fixed as Yah-, is the mainstream near-consensus reconstruction, resting on four converging lines: the patristic transcriptions (Iabe / Iaoue), the theophoric name-forms (Yeho- / -yahu / -yah), a yaqtil imperfect of "to be" fitting the burning-bush ehyeh, and the short forms Yah and Yahu. Honest caveat: it is a reconstruction, not a recording — the exact second-syllable vowels and the simple-vs-causative stem stay open, and the overreach to resist is the Sacred-Name insistence that a fixed spelling is a matter of obedience.
George Howard's 1977 thesis — that the New-Testament authors wrote the Name יהוה in their Old-Testament quotations and that the universal Kyrios of the surviving manuscripts is a later scribal substitution — is the scholarly prop under the New World Translation's restoration of "Jehovah" 237 times in the New Testament. Its Old-Testament half is genuine: some pre-Christian Greek copies did not use Kyrios but wrote the Name in square Hebrew (P. Fouad 266), paleo-Hebrew (the Naḥal Ḥever Minor Prophets), or as Iao (4QLXXLevb). But the New-Testament half is weak: not one of the thousands of surviving Greek witnesses preserves the Name, the Fathers record no controversy over so vast an edit, and the New Testament deliberately trades on Kyrios to identify Jesus with the LORD (Romans 10:13 / Joel 2:32; Philippians 2:9–11) — a reconstruction about lost autographs that every extant copy contradicts.
