And this one hath called unto that, and hath said: `Holy, Holy, Holy, is Jehovah of Hosts, The fulness of all the earth is His glory.'

Meaning in one sentence
Isaiah 6:3 shows the seraphim crying "holy, holy, holy" and declaring that God's glory fills the earth. Learn the meaning of this powerful verse.
Context
Isaiah 6 is the prophet's account of his calling. It happens in the year King Uzziah dies, a time of political uncertainty. Isaiah sees the Lord seated on a high throne, the train of His robe filling the temple. Above the throne stand the seraphim, each with six wings. They cover their faces and feet in reverence and fly with two wings. The seraphim call to one another in antiphonal song, declaring God's holiness. The whole scene shakes the temple and fills it with smoke. This vision prepares Isaiah for the difficult mission ahead. He is confronted with God's majesty, his own sin, and the grace that cleanses him. The cry of the seraphim sets the theme for Isaiah's entire ministry: God is holy, and His glory covers the earth.
Key Words
The word translated holy is qadosh, which means set apart, distinct, utterly other. When the seraphim repeat it three times, they are not adding emphasis only; they are declaring that God's holiness is complete and perfect. The number three in Hebrew often signals fullness or intensity. This is not a God who is a little bit holy; He is holy through and through. Each repetition strikes a new chord of awe.
Glory is kavod, originally a word for weight or heaviness. It speaks of God's worth, His substantial presence. The seraphim see that the whole earth is full of this glory. Not just the temple, not just the heavens, but every part of creation.
The phrase fullness of the whole earth uses melo, which means that which fills something to completion. The earth is not partly covered by God's glory; it is entirely filled. This is not a future hope only but a present reality that the seraphim celebrate. God's holy presence saturates everything. Our worship acknowledges that we live in a world that already belongs to Him.
How Christians Read This Verse
Many Christian traditions have found deep meaning in this verse. Wesley and other Methodist commentators saw the triple holy as an implication of the Trinity, three Persons united in one divine nature. The Cambridge Bible notes that ancient church fathers also saw a Trinitarian allusion here. Reformed commentators like Calvin emphasize that the angels' example calls us to a life of praise that matches our profession. Keil and Delitzsch highlight the antiphonal nature of the song, showing that the seraphim respond to one another in continuous worship. Adam Clarke connects this to the practice of alternate singing in the Old Testament, from Miriam's song at the Red Sea to the choirs in Ezra. Across traditions, Christians agree that this verse confronts us with God's majestic holiness and calls us to awe.
A common misunderstanding
A common misreading is to think the whole earth is full of his glory refers only to beautiful sunsets and natural wonders. While creation does declare God's glory, the context is about God's manifest presence filling all things as fully as the temple was filled with smoke and the seraphim's song. In fact, the Hebrew word for fullness (melo) means that which fills completely. God's glory is not just visible in nature; it actively saturates the entire earth, and one day every creature will see it. This changes how we see our daily world: God is already present in every place.
Living This Out
What does this verse ask of you this week? When you feel small or overwhelmed by the state of the world, remember the seraphim's song. They did not ignore the brokenness below; they saw the throne above. You can start your day by whispering holy, holy, holy as a way of declaring that God is still King. Let that phrase realign your thoughts before you check the news or face a difficult conversation. The seraphim sang to one another, and you can do the same in your community. Pick one friend and text them a reminder of God's holiness and glory. Let this verse become a rhythm in your life, not just a memory verse. The earth is full of His glory; you can look for it today.
Main takeaway: God's holiness is utterly perfect, and His glory fills the entire earth, inviting our awe and worship.
For Families
For ages 5, 8
God is so holy that the angels say it three times. They want us to know He is perfect and special. The whole earth is full of His glory, so everywhere we go we can remember God is there.
For ages 9, 12
The seraphim are angelic beings who stand in God's presence and sing about His holiness. When they say holy three times, it shows that God is completely set apart from everything else. He is not like us in any way; He is perfect and pure. And they also say that the whole earth is full of His glory. That means God's presence fills every place, even when we can't see it. This week, try to notice one thing each day that reminds you of God's glory. Maybe it's a sunrise, a kind word, or a moment of peace. That is His glory shining through.
