The name Yahweh comes from the Hebrew verb hayah, “to be,” and it is tied to the words God spoke at the burning bush: “I AM WHO I AM.” In Exodus 3, Moses asks what name he should give to the Israelites, and God answers with a name that describes His own being rather than a title borrowed from human language. The name means that God is self-existent, eternal and unchanging — He does not derive His life from anyone or anything. The related form Jehovah is the traditional English rendering of the same Hebrew name, built from the consonants YHWH with the vowels of Adonai. So the short answer is this: Yahweh means “I am,” the God who simply is, and who remains the same forever.
What exactly does “I AM WHO I AM” mean in Exodus 3?
The scene is Mount Horeb. God has called Moses from the burning bush and sent him to bring Israel out of Egypt. Moses objects that he is nobody, and then asks the practical question: if the people ask for the name of the God who sent him, what should he say? God’s answer is the name itself.
And God said unto Moses, I AM THAT I AM: and he said, Thus shalt thou say unto the children of Israel, I AM hath sent me unto you. — Exodus 3:14 (KJV)
Several things are packed into that phrase. First, God is self-existent: He has His being from Himself, not from any source outside Himself. Second, He is eternal and unchangeable — “the same yesterday, to-day, and for ever.” Third, He is beyond full human comprehension; the name itself puts a limit on our curiosity. Fourth, He is faithful and true to His promises. Matthew Henry’s comment on this passage gathers those four ideas together and notes that the name explains the name Jehovah.
A few verses later God adds: “And I appeared unto Abraham, unto Isaac, and unto Jacob, by the name of God Almighty, but by my name JEHOVAH was I not known to them” (Exodus 6:3, KJV). The patriarchs knew God’s power; Moses and Israel were to know Him by the name that speaks of His unchanging covenant faithfulness.
Is Yahweh the same name as Jehovah, and where does the Tetragrammaton fit?
The Hebrew text of the Old Testament gives God’s personal name as four consonants: YHWH. Scholars call this the Tetragrammaton, from the Greek for “four letters.” Because ancient Hebrew was written without vowels, later readers had to supply them, and Jewish practice came to read the name as Adonai (“Lord”) rather than pronounce it aloud. When the Masoretes added vowel points to the text, they put the vowels of Adonai with the consonants YHWH. English translators who tried to represent that combination produced the form Jehovah; modern scholars generally reconstruct the original pronunciation as something like Yahweh.
So Jehovah and Yahweh are not two different names. They are two ways of rendering the same four letters. The King James Version and the American Standard Version use “Jehovah” in a number of places, while most modern translations print “the LORD” in small capitals to signal that the Hebrew behind the English word is YHWH. A contraction of the name also appears in worship: Psalm 68:4 calls God “JAH,” a short form of Jehovah.
What does the name Yahweh tell us about God’s character?
Because the name means “I am,” it is a statement about God’s nature before it is a label. That nature shows up in how God acts. In Isaiah, the same God who says “I am he” also says He is the first and the last, the only God, and the one who holds His people’s hand.
Thus saith Jehovah, the King of Israel, and his Redeemer, Jehovah of hosts: I am the first, and I am the last; and besides me there is no God. — Isaiah 44:6 (ASV)
The name is not abstract. It is the ground of comfort. Because God is unchanging, His promises do not shift. Because He is self-existent, He is never exhausted by the needs of His people. Because He is eternal, He is not limited by time the way we are. The prophet Malachi puts it plainly: God does not change, and that is why Jacob’s descendants are not consumed (Malachi 3:6).
This is why the name is so often connected with redemption. In Isaiah 43, God says, “I am Jehovah, your Holy One, the Creator of Israel, your King” (Isaiah 43:15, ASV). The God who simply is also saves, guides and keeps.
What does the name Yahweh mean for Christians today?
The New Testament does not discard the name; it identifies the Lord with Jesus. When Jesus says, “Before Abraham was, I am” (John 8:58), His hearers understand the claim. The One who spoke to Moses at the bush is the One who took flesh and dwelt among us. Revelation opens with grace and peace from “him which is, and which was, and which is to come” (Revelation 1:4, KJV), and later the Lord says, “I am Alpha and Omega, the beginning and the ending… which is, and which was, and which is to come, the Almighty” (Revelation 1:8, KJV).
For everyday faith, the meaning of Yahweh lands in three places. It means God is not a distant idea but a personal God who gives His name to His people. It means His character does not change with circumstances, so we can bring Him our fears. And it means our security rests in who He is, not in how strong we feel. The “I AM” is the same God who says, “Fear thou not; for I am with thee” (Isaiah 41:10, KJV).
How should this name shape the way we read and pray?
First, read the passages where the name appears and let the context teach you. Exodus 3, Exodus 6, Isaiah 41–48 and Revelation 1 are good starting points. Notice how often the name is joined to rescue, covenant and comfort.
Second, pray with the name in view. When you pray to the Father through the Son, you are praying to the God whose name means “I am” — the God who is not caught off guard by your situation and who does not change His mind about His promises.
Third, keep this in the community of faith. A local church, a pastor and trusted believers are the ordinary means God uses to help us understand Scripture and to steady us when life is hard. If reading about God’s name has stirred up anxiety or heavy questions, speak with a pastor or a mature believer in person.

The name Yahweh is not a puzzle to be solved so much as a person to be trusted. “I AM WHO I AM” is God’s own answer to the question of who He is — and every page of Scripture after Exodus 3 is, in one way or another, that answer worked out in history, until the day when the One who is comes again.
Questions readers ask
Does Yahweh literally mean “I am”?
Yes, in the sense that the name is built on the Hebrew verb “to be” and is explained by God’s own words in Exodus 3:14, “I AM THAT I AM.” It points to God as self-existent, eternal and unchanging rather than describing a quality He merely has.
Why do some Bibles say “Jehovah” and others say “the LORD”?
Both represent the same four Hebrew consonants, YHWH. “Jehovah” is an older English form that combines those consonants with the vowels of Adonai; “the LORD” in small capitals is a modern convention that signals the same Hebrew word without attempting a pronunciation.
Is Yahweh the Father only, or does the name apply to Jesus too?
Christians have historically read the New Testament as identifying Jesus with the God of Israel. When Jesus says “Before Abraham was, I am” in John 8:58, He uses the language of Exodus 3, and Revelation applies the same “which is, and which was, and which is to come” wording to Him.
How can I study the name of God further?
Start with the passages where the name appears, such as Exodus 3 and 6, Isaiah 41–48 and Revelation 1, and read them alongside a trusted commentary. A pastor or mature believer in a local church can help you work through the Hebrew background and the theological questions it raises.
