The Tetragrammaton is the four-letter Hebrew name of God: יהוה, usually written in English as YHWH. Because the Hebrew text was written with consonants only, nobody today can be certain how it was originally spoken. The common scholarly reconstruction is Yahweh (roughly YAH-way). The traditional English form is Jehovah (jeh-HOH-vah). Both are attempts to put vowels into the same four consonants. The original pronunciation was lost because Jewish readers stopped saying the name aloud and said Adonai (“Lord”) instead. So the honest answer is: we can say it, but we cannot prove we are saying it the way Moses did.
What exactly is the Tetragrammaton?
The word Tetragrammaton is Greek for “four letters.” It refers to the four Hebrew consonants י (yod), ה (he), ו (waw), ה (he) — YHWH. This is the name by which God revealed Himself to Israel. In Exodus 6, God says to Moses:
I am the LORD. I appeared to Abraham, to Isaac, and to Jacob as God Almighty, but by My name the LORD I did not make Myself known to them. — Exodus 6:2-3 (BSB)
In that BSB rendering, “the LORD” in small capitals stands in for the Hebrew YHWH. The same is true in most English Bibles. When you see LORD in capitals in the Old Testament, the translator is telling you the Hebrew has the four letters.
The name is tied to God’s self-description at the burning bush:
God said to Moses, “I AM WHO I AM. This is what you are to say to the Israelites: ‘I AM has sent me to you.’” — Exodus 3:14 (BSB)
That connection is why the name is often explained as the self-existent one or the unchanging, eternal God. Easton’s Bible Dictionary takes the meaning of the word from Exodus 3:14 to be the unchanging, eternal, self-existent God, the “I am that I am,” a covenant-keeping God.
Why is the original pronunciation uncertain?
Biblical Hebrew was written without vowels. Vowel sounds were supplied by the reader from memory and habit. That works fine while a language is spoken, but it becomes a problem when a name is deliberately avoided in speech for centuries.
By the time of the Second Temple, Jewish readers had stopped pronouncing the name. Easton’s Dictionary records the practice: the name “was held by the later Jews to be so sacred that it was never pronounced except by the high priest on the great Day of Atonement,” and elsewhere readers said Adonai instead. That custom rested on a reading of Leviticus 24:16, though Easton calls that reading a false interpretation of the verse.
When medieval scribes (the Masoretes) added vowel points to the Hebrew text, they did something practical. They kept the consonants of YHWH and added the vowel points of Adonai — the word readers actually said. That combination is the raw material behind the English form Jehovah. It is not a record of how the name was spoken in ancient Israel; it is a record of how readers avoided speaking it.
So the uncertainty is not a modern doubt. It is the direct result of a very old and very reverent practice.
How do you actually say Yahweh and Jehovah?
Yahweh is the reconstruction most Hebrew scholars prefer. It is usually said YAH-way, sometimes YAH-veh. The reasoning is partly comparative: the short form Yah appears in names and in the Psalms (“Hallelujah” ends with it), and early Greek writers transcribed the name in ways that point toward a two-syllable form like Yahweh. That is strong evidence, but it is still reconstruction, not a recording.
Jehovah is the traditional English form, said jeh-HOH-vah. It entered English through the Latin of the Middle Ages and became fixed in the King James Version at a handful of places where the Hebrew actually has YHWH. The KJV prints it in capitals, for example in Exodus 6:3 and Psalm 83:18. The American Standard Version of 1901 used “Jehovah” far more widely, which is why this site quotes the ASV whenever a passage contains the name.
Both pronunciations are in wide use. Neither is a sin to say. Neither is a magic formula. What matters is that the name refers to the one true God, and that He is addressed with reverence.
Should Christians say the name aloud at all?
Faithful Christians have answered this differently, and the differences are worth stating fairly.
Many Jewish readers, and some Christians who follow their reasoning, treat the name as too holy for ordinary speech and say Adonai or “the Lord” instead. This is a position of reverence, not superstition, and it has deep roots.
Most Christian traditions read the Old Testament’s commands to call on the name of the Lord as an invitation, not a prohibition. They sing “Praise the name of the LORD” from Psalm 113 without hesitation:
Praise, O ye servants of the LORD, praise the name of the LORD. Blessed be the name of the LORD from this time forth and for evermore. — Psalm 113:1-2 (KJV)
Jehovah’s Witnesses use “Jehovah” constantly and regard the name as central to worship. This site is not affiliated with them and differs from them on several important doctrines, but their use of the name is not the point of difference. Historic Trinitarian Christians also honour the name; they simply read it through the fuller revelation of the New Testament, where Jesus is called Lord.
A practical rule many believers follow: read “the LORD” as the LORD when you read aloud, and use Yahweh or Jehovah in study and discussion when you are talking about the name itself.
What should you do with the name?
The Tetragrammaton is not a puzzle to solve but a person to know. Psalm 106:8 says God saved Israel “for his name’s sake, that he might make his mighty power to be known.” The name is bound up with God’s character and His saving acts, not with a syllable.
If you want to go further, read Exodus 3 and Exodus 6 slowly, in a translation that marks the divine name. Notice how often the Psalms call God’s people to praise the name. Pray the Psalms back to God, using whatever form your conscience allows. And do this in the company of a local church, where the name of the Lord is confessed and sung week by week.
Pronunciation is a small thing. Knowing the One who bears the name is everything.
Questions readers ask
Is “Jehovah” a wrong pronunciation of the Tetragrammaton?
It is not the original pronunciation, and most scholars think Yahweh is closer. But “Jehovah” is a long-established English form with centuries of use in translation and worship. It is a faithful attempt to read the same four consonants, not a corruption of them.
Why did the Jews stop saying the name?
They treated the name as uniquely holy and read Adonai (“Lord”) in its place, a practice Easton’s Dictionary ties to a reading of Leviticus 24:16. The custom was already old by the time vowel points were added to the Hebrew text.
Does the New Testament tell us how to pronounce it?
No. The New Testament was written in Greek and uses Kyrios (“Lord”) where the Old Testament has YHWH. It never spells out the Hebrew pronunciation, which is one reason the original sound remains uncertain.
Which pronunciation should I use in prayer?
Either is acceptable, and many Christians simply say “Lord.” What Scripture emphasises is reverence and truth, not a particular set of vowels. If you are unsure, follow the practice of your local church.
