Did Moses Really Introduce God's Name - YHWH?
I was recently challenged on this question, and rightly so...
A friend recently asked: "If God didn't reveal His name to Moses until Exodus 6:3, how did Jacob already know it?" Great question. And it goes even deeper than Jacob.
Look at the record. Eve used the name in Genesis 4:1 . People were "calling on the name of Yahweh" as far back as the time of Enosh ( Gen. 4:26 ). Abraham built an altar and "called on the name of Yahweh" ( Gen. 12:8 ). Isaac did the same ( Gen. 26:25 ). And Jacob, after his famous ladder vision, clearly knew exactly who he was dealing with.
So what is Exodus 6:3 actually saying?
The Text Itself
God says to Moses: "I appeared to Abraham, to Isaac, and to Jacob as El Shaddai — God Almighty — but by my name Yahweh I did not make myself known to them."
On the surface, that seems to flatly contradict Genesis. But here's the key: this is not about the name itself. It's about the meaning behind the name.
The patriarchs knew the name. We know this because the manuscript evidence is overwhelming. The name Yahweh(Hebrew: YHWH) appears in the Bible as far back as Genesis 2:5 — woven naturally into the narrative long before Moses was born — and continues appearing hundreds of times through Genesis and into Exodus. This is not editorial accident. Ancient manuscripts, including the Dead Sea Scrolls discovered in 1947, confirm that YHWH was present in the text from its earliest recoverable form, not added later. The name was always there. What Israel was about to witness was the meaning of that name made visible in real history.
So, the patriarchs really did know the name. What they had not yet witnessed was what the name meant in action. Yahweh — derived from the Hebrew word "YHWH"— means something like "I AM, I WAS, I WILL BE." It is the name of the God who keeps covenant, who fulfills promises, who moves in history on behalf of His people. The patriarchs received the promises. Moses and Israel were about to watch them fulfilled — plagues, exodus, Red Sea, Sinai. That is the revelation of Exodus 6:3 . Not the letters. The living reality behind them.
Think of it this way: you might know someone's name for years before you truly know them. The patriarchs knew His name. Israel was about to know Him.
A Bonus Wrinkle: What About "Jehovah"?
Here's something most people have never considered. Ancient Hebrew was written with consonants only — no vowels. So the divine name was always written as four consonants: YHWH, called the Tetragrammaton.
Jewish tradition held this name too sacred to speak aloud. So when scribes(the Leningrad Codex of 1008 AD, the work of the Masoretes) copied the text, they placed the vowel sounds of a substitute word — Adonai (Lord) — beneath YHWH's consonants, as a reminder to say "Adonai" instead of pronouncing the name. (This was the Leningrad Codex of 1008 AD, the work of the Masoretes.) Medieval Christian scholars, not knowing this scribal tradition, read the hybrid combination literally and produced the word "Jehovah" — a word that never actually existed in ancient Hebrew. It first appeared in English around 1530 with William Tyndale.
So why do so many still use "Jehovah"? Largely because of Strong's Concordance, the beloved 19th-century Bible reference tool, and the 1901 American Standard Version, which consistently used "Jehovah" throughout. Both became enormously influential in Protestant churches and the name stuck — not because it's more accurate, but because of tradition and familiarity.
Most Hebrew scholars today believe the original pronunciation was closer to "Yahweh," supported by fragments of ancient names (like Hallelu-Yah — "Praise Yah"), early Church writings, and the Samaritan oral tradition.
So What Do We Do With All This?
Neither "Jehovah" nor "Yahweh" should become a hill to die on. What matters is understanding who the name points to.
This is Yahweh — the One who, when the heavens and earth were finished and every host of them complete, rested on the seventh day and set it apart. He is not one deity among many. He is the Creator of all that exists, and it is precisely because He made everything that He alone has the right to say, "You shall have no other gods before Me." That command in Exodus 20 isn't divine ego — it's a statement of reality. There are no others with a legitimate claim. The so-called gods of the nations made nothing. Yahweh made everything.
And this same Creator — the self-existent, eternal "YHWH" — is the One who entered into covenant with Abraham, whispered to Isaac, met Jacob at the top of a ladder, and then showed Moses what His name actually looked like when it was unleashed in history.
Exodus 6:3 is not a contradiction. It is a drumroll — the moment before the God who made the universe steps openly onto the stage of human redemption and says, "Now watch what My name means."
