The Name of God: YHWH and the Tetragrammaton
God said to Moses, “I AM WHO I AM,” and he said, “You shall tell the children of Israel this: ‘I AM has sent me to you.’”Exodus 3:14 · World English Bible
Original Language & Text
The personal name of the God of Israel appears in the Hebrew Bible as four consonants, יהוה (YHWH), called the Tetragrammaton ('four letters'), appearing roughly 6,800 times. Ancient Hebrew was written without vowels, and by the Second Temple period the name was considered too sacred to pronounce aloud (based on a strict reading of the third commandment, Exodus 20:7); readers substituted 'Adonai' ('my Lord') or, in some contexts, 'HaShem' ('the Name'). When medieval Masoretic scribes added vowel points to the Hebrew text, they inserted the vowels of 'Adonai' (or sometimes 'Elohim') beneath YHWH's consonants as a reading cue, producing the hybrid form later Christian scholars misread literally as 'Jehovah' (attested from the 12th-16th centuries). The reconstructed original pronunciation 'Yahweh' is based on transliterations in Greek patristic sources and grammatical analysis of the verb root 'hayah' ('to be'), connecting it to Exodus 3:14's 'ehyeh asher ehyeh' ('I am who I am' or 'I will be what I will be').
Key Terms in the Original Language
the Tetragrammaton, God's personal name, traditionally considered too sacred to pronounce
The name's original pronunciation was lost after Jewish tradition substituted “Adonai” (“my Lord”) aloud; “Jehovah” and “Yahweh” are both modern scholarly reconstructions, not a recovered original pronunciation known with certainty.
“I am” or “I will be” (Exod. 3:14, “I AM WHO I AM”)
This is a form of the ordinary Hebrew verb “to be,” hayah; because Hebrew doesn't sharply distinguish present and future the way English does, the phrase has been read both as a philosophical statement of self-existent being and as a more relational promise, “I will be [with you].”
History & Authorship
In ancient Israel the divine name was apparently spoken relatively openly (it appears in personal names, blessings, and inscriptions like the Lachish letters and Mesha Stele), but reverence for it intensified during and after the Babylonian exile, and by the Second Temple period Jewish practice avoided pronouncing it entirely, substituting 'Adonai' in speech, a custom reflected in the Septuagint's rendering of YHWH as 'Kyrios' (Lord). This avoidance became fixed rabbinic practice, and the true pronunciation was effectively lost to common knowledge over centuries, surviving mainly in scholarly reconstruction. Christian translators inherited the 'Lord'/'Kyrios' substitution pattern in most English Bibles (rendering YHWH as 'LORD' in small capitals), while some Reformation and post-Reformation scholars popularized 'Jehovah' as a literal (but linguistically mistaken) reading of the vowel-pointed form; the American Standard Version (1901) and Jehovah's Witnesses' New World Translation later used 'Jehovah' throughout. Since the 19th-20th centuries, comparative Semitic philology has favored 'Yahweh' as the more historically accurate reconstruction.
How This Debate Developed
-
c. 3rd c. BC onward
Avoidance of pronouncing YHWH
Second Temple Jewish practice increasingly substitutes “Adonai” aloud rather than pronouncing the name directly.
-
3rd–2nd c. BC
Septuagint renders YHWH as “Kyrios”
Cements the “Lord” substitution pattern that carries into how the New Testament quotes the Old.
-
6th–10th c. AD
Masoretes add vowel points
Later scribes add “Adonai”'s vowels to the consonants YHWH, a hybrid later misread as “Jehovah.”
-
19th–20th c.
“Yahweh” reconstruction
Modern scholarship converges on “Yahweh” as the more likely original pronunciation, while “Jehovah” remains in popular and some denominational use.
The Popular / Mainstream View
Most Jewish practice today continues the ancient custom of not pronouncing the divine name, substituting 'Adonai' in liturgical reading or 'HaShem' in everyday speech, and most English Bibles used by Protestants and Catholics render YHWH as 'LORD' (small capitals) rather than transliterating it, following the Septuagint/Vulgate tradition. Among scholars and in some Christian traditions (and various English translations like the Jerusalem Bible and some scholarly works), 'Yahweh' is used as the best reconstructed historical pronunciation, while 'Jehovah' persists primarily in certain historic hymns, the Jehovah's Witnesses' theology and the New World Translation, and some older English translations.
Minority & Alternative Views
Jehovah's Witnesses and 'Jehovah' usage
Jehovah's Witnesses hold that the divine name should be actively used and proclaimed rather than avoided, using 'Jehovah' throughout their New World Translation (including in New Testament passages where they believe YHWH was originally present before later scribal substitution with 'Kyrios'), a textual claim not supported by any extant Greek New Testament manuscript and rejected by mainstream textual scholars.
Sacred Name movement
A range of smaller Christian groups (sometimes called Sacred Namers) insist on using a specific transliterated form of the divine name (variously 'Yahweh,' 'Yahuah,' or others) and sometimes a Hebrew form of Jesus's name ('Yahshua' or similar), arguing that substituting generic titles like 'God' or 'LORD' obscures a name they consider essential to proper worship and identity.
Rabbinic prohibition on any pronunciation
Traditional Orthodox Judaism holds the correct pronunciation should not be reconstructed or spoken at all under any circumstances outside historic Temple ritual, treating scholarly reconstructions like 'Yahweh' as inappropriate even as an academic exercise, since the prohibition is understood as a matter of ongoing religious law (halakha), not merely a lost linguistic detail.
What Scholars Say
It is well established among historical linguists that 'Jehovah' arose from a Christian misreading of Masoretic vowel points borrowed from 'Adonai' and does not reflect how the name was ever actually pronounced in antiquity; this is essentially uncontested outside of specific theological communities that retain 'Jehovah' for tradition's sake. 'Yahweh' is the scholarly consensus reconstruction, supported by early Greek transliterations (e.g., in Clement of Alexandria and other patristic sources rendering it 'Iabe') and by the name's likely derivation from the Hebrew verb 'to be,' though full certainty about ancient pronunciation is unattainable given the absence of vocalized ancient Hebrew sources. What remains a matter of religious practice rather than linguistics is whether the name should be spoken, written, or substituted — a question of law and reverence, not translation accuracy.
