The Tetragrammaton is the four Hebrew letters י (yod), ה (he), ו (waw), ה (he) — YHWH — that spell the personal name of God in the Old Testament. In English Bibles it is usually rendered “the LORD” in small capitals, or “Jehovah” in some older translations. It is used for three main things: to name God as the one who revealed Himself to Israel, to mark Him off from every other god, and to give His people a name to call on in worship, prayer and blessing. The name appears about 6,800 times in the Hebrew Scriptures, from Genesis to Malachi. It is not a magic formula, and it is not a secret code. It is God’s own self-given name, and its use is tied to knowing Him, trusting Him and speaking of Him rightly.
What exactly is the Tetragrammaton?
The word “Tetragrammaton” comes from Greek and simply means “four letters.” Those four letters are the consonants of God’s covenant name. Ancient Hebrew was written without vowels, so the original pronunciation is not certain today. Most scholars suggest something like “Yahweh”; the older English form “Jehovah” arose later by combining the consonants with the vowels of another word.
When God called Moses at the burning bush, He gave the name in direct speech:
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.’” God also told Moses, “Say to the Israelites, ‘The LORD, the God of your fathers—the God of Abraham, the God of Isaac, and the God of Jacob—has sent me to you.’ This is My name forever, and this is how I am to be remembered in every generation. — Exodus 3:14-15 (BSB)
Here the name is bound up with God’s self-existence and His faithfulness to His promises. It is not a label He picked up; it is who He is.
Why does the name matter in the Bible?
The name matters because the Bible treats it as God’s own self-revelation. To know the name is to know the God who acts in history. The psalmist prays:
May they know that You alone, whose name is the LORD, are Most High over all the earth. — Psalm 83:18 (BSB)
God also says through Isaiah:
I am the LORD; that is My name. I will not yield My glory to another or My praise to idols. — Isaiah 42:8 (BSB)
So the Tetragrammaton is used to distinguish the God of Israel from the idols of the nations. It is His identity, His reputation and His claim on His people.
How is the Tetragrammaton used in worship and prayer?
In the Old Testament, calling on the name of the LORD is a regular way of describing worship. It means approaching God as He has revealed Himself, not as we imagine Him. The Psalms are full of this:
From where the sun rises to where it sets, the name of the LORD is praised. — Psalm 113:3 (BSB)
And:
O LORD, our Lord, how majestic is Your name in all the earth. You have set Your glory above the heavens. — Psalm 8:1 (BSB)
So the name is used in praise, in blessing, in oath-taking and in prayer. It is not used as a talisman or a chant to manipulate God. The third commandment warns against misusing it:
You shall not take the name of the LORD your God in vain, for the LORD will not leave anyone unpunished who takes His name in vain. — Exodus 20:7 (BSB)
That command is not mainly about avoiding a certain sound. It is about not attaching God’s name to lies, empty oaths or false worship.
Do Christians use the Tetragrammaton today?
Yes, but in different ways. Most modern English Bibles follow the ancient Jewish practice of reading “Adonai” (Lord) in place of the name, and so they print “the LORD” in small capitals. Others, especially older translations like the King James Version and the American Standard Version, use “Jehovah” in many places. The ASV, for example, reads at Psalm 83:18:
That they may know that thou alone, whose name is Jehovah, Art the Most High over all the earth. — Psalm 83:18 (ASV)
Christians also believe the name belongs to Jesus. He said to the Father:
I have revealed Your name to those You have given Me out of the world. — John 17:6 (BSB)
And Paul writes of Jesus:
Therefore God exalted Him to the highest place and gave Him the name above all names, that at the name of Jesus every knee should bow, in heaven and on earth and under the earth, and every tongue confess that Jesus Christ is Lord, to the glory of God the Father. — Philippians 2:9-11 (BSB)
So for Christians, the God of the Old Testament is the God and Father of Jesus Christ. To pray “Our Father in heaven, hallowed be Your name” (Matthew 6:9) is to honour the same name.
Is there a right or wrong way to use the name?
The Bible does not give a pronunciation guide, and it does not command a particular spelling in English. What it does command is reverence. We are to use the name in truth, not in superstition. We are to call on God as He has revealed Himself, not as a charm. And we are to speak of Him with awe, because He is not like us.
Some Christians avoid saying the name aloud out of reverence, following the ancient Jewish custom. Others use “Yahweh” or “Jehovah” in reading and singing. Still others simply say “the Lord.” These are differences of practice, not of salvation. What matters is that we know the God whose name it is.
How should this shape your own reading and prayer?
When you see “the LORD” in small capitals in your Bible, remember that it stands for the Tetragrammaton. Let it slow you down. That name is God’s way of saying, “This is who I am, and I am with you.” Use it in prayer as a reminder that you are speaking to the living God, not to an idea. Use it in worship as a way of giving Him the honour He alone deserves. And use it in your own study to see how often the Bible ties God’s name to His saving acts.
If you want to go further, read Exodus 3 and 6, Psalm 113, and John 17 slowly. Ask your pastor or a trusted believer to help you see how the name of God runs through the whole story of Scripture. And keep pointing your heart to the One who has made His name known in Jesus Christ.

Questions readers ask
Is the Tetragrammaton the same as Jehovah?
Yes and no. The Tetragrammaton is the four Hebrew letters YHWH. “Jehovah” is a much later English form that combines those consonants with vowels from another word. It is a traditional way of writing the name, but it is not the original pronunciation.
Can Christians pray using the Tetragrammaton?
Christians have always prayed to the God of Israel, who revealed Himself by that name. Some use “Yahweh” or “Jehovah” in prayer, while others say “Lord” or “Father.” What matters is that we pray to the true God through Jesus Christ, not that we use one particular form of the name.
Why do some Bibles say “LORD” instead of the Tetragrammaton?
Following an ancient Jewish custom, many Bible translations read “Adonai” (Lord) in place of the divine name, and so they print “LORD” in small capitals. This is a way of showing reverence and following long-standing practice. Other translations, like the King James Version and the American Standard Version, use “Jehovah” in many places.
