Yahweh in Exodus 3:13-15: God's Name Explained
Short answer: In Exodus 3:13-15 God answers Moses' question about his name by revealing himself as Yahweh, the self-existent, covenant-keeping God of Abraham, Isaac, and Jacob. The name is not a magic word or a secret code; it is God's own disclosure of his identity. It appears throughout the Old Testament, most often where God acts to save, judge, or make himself known. Exodus 6:2-3, Deuteronomy 6:4, Psalm 83:18, Isaiah 42:8, and Jeremiah 16:21 all assume that Yahweh is the personal name of Israel's God, distinct from the generic titles translated God and Lord. The verses about Yahweh are therefore about who God is, not merely what he is called.
What Moses actually asked in Exodus 3:13
Moses is standing before a burning bush that is not consumed. God has already spoken to him, called him by name, and commissioned him to bring Israel out of Egypt. Moses, understandably, wants credentials. He raises a practical objection: when he returns to the Israelites and announces that the God of their fathers has sent him, they will want to know the name of this God. Titles such as God Almighty or the God of your fathers are not enough here. In the ancient world, to know a deity's name was to have some handle on the deity's identity and character.
Notice the shape of the question. Moses does not ask, what is your power like, or what will you do. He asks, what is his name. The question is about identity. He is about to appear before a people who have lived for centuries in a land saturated with named gods, and he needs to be able to say precisely which God has acted. The rest of Scripture treats that name with weight precisely because it was given as an answer to a real, anxious question, not as a riddle for scholars.
This matters for how we read every later verse about Yahweh. When Psalm 83:18 prays that the nations may know that you alone, whose name is Yahweh, are the Most High over all the earth, it is picking up the same concern Moses had. The name identifies. It distinguishes the living God from the idols and from every rival claim. The verses about Yahweh are, at root, verses about knowing who is actually God.
The answer God gave: I am that I am
God does not rebuke Moses for asking. He answers. The answer recorded in Exodus 3:14 is dense and much discussed: I AM WHO I AM. He then tells Moses to say to the Israelites that I AM has sent him. And in the next verse he expands the answer into the name by which he is to be remembered throughout all generations. The self-designation carries the sense of being, of existence, of presence. God is not one being among many who happen to have a name; he is the one who is.
It is worth being honest about the limits here. The Hebrew of Exodus 3:14 has been translated and interpreted in several faithful ways across centuries, and serious students of the text differ over the precise nuance. What the passage plainly does is tie the name directly to God's self-existence and to his presence with his people. It does not turn the name into a formula to be pronounced for magical effect, and it does not license speculation beyond what the text says. The point is the God who is, not a verbal talisman.
Exodus 6:2-3 picks up the thread when God says to Moses, I am Yahweh. He goes on to say that he appeared to the patriarchs as God Almighty but did not make himself known to them by his name Yahweh in the same way. The revelation is progressive. The name is not a new invention; the depth of what it means is being unfolded as God moves to redeem a people from slavery. That is why the exodus is the great Yahweh event of the Old Testament.
Yahweh as the covenant name of Israel's God
Throughout the Old Testament, Yahweh is the personal, covenant name of the God of Israel. When God makes promises to Abraham, Isaac, and Jacob, he binds himself by his own name. When he brings Israel out of Egypt, he acts for his name's sake, so that it might be known among the nations. The name is not a cold label on a file; it is the signature of a God who commits himself to a particular people and keeps his word to them across generations.
This is why Deuteronomy 6:4 stands at the head of Israel's confession. Hear, Israel: Yahweh is our God. Yahweh is one. The verse names him and then confesses his oneness. The people are not left with a vague sense of the divine. They are told who this God is, that he is theirs by covenant, and that he is one, not a pantheon. Every command that follows in that chapter, including the call to love God with heart, soul, and strength, rests on the identity established in that opening line, and on the name that carries it.
So when the Old Testament speaks of the name of Yahweh, it is often shorthand for God's revealed character and his claim on his people. To call on the name of Yahweh is to appeal to him as he has made himself known. To profane the name is to treat that revelation with contempt. The name and the God are inseparable, which is why the biblical writers can move so quickly from speaking of God's name to speaking of God himself.
Why God says, that is my name
Isaiah 42:8 is one of the most direct statements in Scripture about the name: I am Yahweh. That is my name. I will not give my glory to another, nor my praise to engraved images. The context is a confrontation with idolatry. God is not merely asserting a preference in titles; he is drawing a line between himself and every manufactured god. His name is tied to his glory, and his glory will not be handed over to something carved by human hands.
There is a pastoral edge to this. The verses about Yahweh are not abstract trivia for word studies. They answer a real human temptation, which is to blur the living God into whatever we find most convenient, or to domesticate him into a tribal mascot. Isaiah 42:8 refuses that. The God who is, the one whose name is Yahweh, will not be reshaped to suit us. He will not share his glory with our preferred images, ancient or modern.
Jeremiah 16:21 makes the same point from the other direction. God says through the prophet that he will cause his people to know his hand and his might, and then they will know that his name is Yahweh. Knowing the name here is not reciting syllables; it is recognizing God's power at work and responding to him as God. In Jeremiah's day that meant judgment and then restoration. The name is taught by what God does, not only by what he says.
Is Yahweh the same as LORD in your Bible?
Many English translations print the word LORD in small capital letters where the Hebrew text has the four-letter name. This is a long-standing convention, rooted historically in reverence for the name and in the practice of reading a substitute aloud. When you see LORD in capitals in a passage like Psalm 83:18 or Deuteronomy 6:4, the underlying Hebrew is the name Yahweh. The World English Bible, from which the quotations in this study are taken, generally transliterates the name as Yahweh, which is why it appears plainly here.
Christians differ in practice about how to pronounce or use the name. Some read Yahweh in public worship; others follow the older custom of saying Lord even where the Hebrew has the name. Faithful believers hold both positions, and Scripture does not settle the pronunciation question for us. What the text does settle is that this is God's revealed name, that it is not a generic title, and that it is to be treated with reverence rather than emptied of content.
One more clarification is worth making. Yahweh is not the name of a different deity from the God and Father of Jesus Christ. The New Testament writers identify Jesus as Lord and apply Old Testament Yahweh texts to him, a pattern that has generated centuries of careful Trinitarian reflection. However one works through the details, the Bible does not present two gods. The God who revealed himself to Moses is the God Christians worship.
What the name Yahweh tells us about God
The name tells us that God is. He is not dependent on anything outside himself for his existence. Moses did not conjure him, Israel did not create him, and no nation sustains him. That is a different kind of claim from anything the surrounding religions made about their gods. It also means God is not silent about who he is. He speaks, he names himself, and he makes his character known through his actions, above all in the exodus.
The name also tells us that God is present. He hears the cry of an enslaved people, comes down to deliver them, and sends Moses. The self-existent God is not a distant principle. He is the God who is with his people in their suffering and who acts on their behalf. The name and the rescue belong together. When God later says that he acts for his name's sake, it means he acts in a way consistent with what he has revealed himself to be.
And the name tells us that God is holy. Isaiah 42:8 ties the name to glory that will not be shared. Jeremiah says that knowing the name comes through experiencing God's hand and might. This is not a name to be thrown around carelessly or used as a slogan. It is the name of the Most High over all the earth, as Psalm 83:18 puts it. To know it rightly is to bow before the one who bears it, and to live as people who belong to him.
Biblical fidelity check
What these passages establish is clear enough: God revealed his name to Moses, the name is Yahweh, and that name identifies him as the self-existent, covenant-keeping, holy God of Israel. The texts also tie the name to God's glory, his acts, and his refusal to share honor with idols. What the passages do not establish is a doctrine of the name as a spoken formula that guarantees results, nor a complete system of pronunciation, nor a claim that the letters themselves carry power apart from the God who revealed them. The Bible does not command a particular modern pronunciation.
A common misreading treats the name Yahweh as a kind of spiritual technology, as though saying it correctly unlocks power or access. That is wrong because it reverses the relationship the text assumes. The name is God's self-disclosure, not our mechanism. He is the one who acts; the name tells us who is acting. Another misreading flattens Yahweh into a generic word for God, so that the specific revelation to Moses loses its force. Both errors ignore the same thing: the name was given so that a particular people could know a particular God, and so that the nations would come to know him too.

Frequently asked questions
What does the name Yahweh actually mean?
The name is tied to the Hebrew verb for being, and the answer God gives in Exodus 3:14 is usually rendered I AM WHO I AM. The sense is that God is the one who is, who exists in himself and is present with his people. Scholars differ over the exact nuance of the Hebrew, and faithful translations handle it in slightly different ways. What is not in doubt is that the name is a self-revelation, not a label God was given by others.
Was Yahweh the name of a separate god before Israel worshiped him?
No. The Bible presents Yahweh as the God of Abraham, Isaac, and Jacob, the one who made the heavens and the earth. Exodus 6:2-3 describes a deeper revelation of the name rather than the introduction of a new deity. Some modern theories have proposed that Israel adopted a Canaanite god, but those arguments rest on reconstructions outside the biblical text, and the Scriptures themselves consistently present one God who reveals his name to his people.
Should Christians say Yahweh or Lord?
Both practices exist among faithful believers. Jewish tradition long substituted a title for the name out of reverence, and many English Bibles follow that convention by printing LORD in small capitals. Other translations and readers use Yahweh directly. Scripture commands reverence for the name without specifying a required pronunciation for modern languages. The important matter is that the name belongs to the living God and should be treated as holy, not used carelessly.
