as when fire kindles the brushwood, and the fire causes the water to boil. Make your name known to your adversaries, that the nations may tremble at your presence!
As when the melting fire burneth, the fire causeth the waters to boil, to make thy name known to thine adversaries, that the nations may tremble at thy presence!
as when fire kindleth the brushwood, and the fire causeth the waters to boil; to make thy name known to thine adversaries, that the nations may tremble at thy presence!
(As fire kindleth stubble--Fire causeth water to boil,) To make known Thy name to Thine adversaries, From Thy presence do nations tremble.
— as fire kindleth brushwood, as the fire causeth water to boil, to make thy name known to thine adversaries, that the nations might tremble at thy presence!
Meaning in one sentence
Isaiah 64:2 shows God’s people praying for him to reveal his power like fire, so that enemies would know his name and tremble.
Context
Isaiah 64 sits at the end of a long prayer that stretches back through chapter 63. The people of Judah are in distress, feeling as if God has hidden his face. They remember the days when he came down in power, at Sinai, in the exodus, and they cry out for him to do it again. “Oh that you would tear the heavens,” they plead, “that the mountains might quake at your presence.” This is not a calm request. It is raw, desperate hope from a nation that knows its own sin and longs for God to act. Verse 2 continues that cry with an image of fire: dry brushwood catching, water boiling over. The prophet is asking for something fierce and unmistakable.
Key Words
The Hebrew word behind “brushwood”, hamasim, has puzzled translators. The older idea was “melting fire,” but many scholars now connect it to an Arabic root meaning “crackling” or “splintering.” It suggests dry twigs that snap and blaze in an instant. That is the picture: God’s presence ignites everything flammable. And “causes the water to boil”, a simple, domestic image of a pot over a hot fire, makes the point even plainer. The heat is too intense for anything to stay as it was. The verse ends with the purpose: “Make your name known to your adversaries, that the nations may tremble at your presence.” The word “tremble” here is not just fear. It is a shaking that comes from recognizing who God is. This is the point of the fire: not destruction for its own sake, but revelation that changes how people respond.
How Christians Read This Verse
Christian interpreters have read this verse as a prayer for a visible, overwhelming display of God’s power. Matthew Henry saw it as the church asking God to “shine forth” and deliver his people. Barnes noted the vividness of the language, connecting it to volcanic imagery in the region. Keil and Delitzsch pointed to the Arabic background of “brushwood” as dry, crackling twigs, emphasizing the swiftness of the fire. Others have focused on the purpose clause: God makes himself known so that even his enemies might recognize him and tremble. Across traditions, there is agreement that the verse portrays a theophany, a coming of God that breaks into human history with unmistakable force. The disagreement lies in how literal the language is meant to be and whether it applies primarily to the return from exile or to a future day of the Lord.
A common misunderstanding
Some read this verse as if God simply enjoys burning up his enemies. But the fire here is not an end in itself. The whole phrase swings toward a purpose: “to make your name known to your adversaries.” The boiling water and blazing brushwood are means, not the goal. God’s desire is that the nations would know who he is, and that knowledge leads to trembling, not just terror. The fire is revelatory, not merely destructive.
Living This Out
You have a situation right now that feels impossible. A relationship that seems beyond repair. A financial strain that keeps tightening. A fear that just won’t leave. This verse gives you language for that moment. You can ask God to come down, not gently, but with the kind of power that changes everything. Not for revenge, but so that everyone involved would know who he is. The prayer is honest: you want the mountains to move, the water to boil. And you trust that when God acts, even those who oppose him will see his name and tremble. This week, bring that one impossible thing to him and ask him to make himself known in it.
Main takeaway: God’s power is not for show but to make himself known, so that even enemies may recognize and fear him.

For ages 5, 8
This verse is a prayer: “God, please come and help us, like a big fire that boils water.” When you feel scared or sad, you can ask God to show how strong he is.
For ages 9, 12
In Isaiah 64, God’s people are crying out for him to show up in a powerful way. They use fire and boiling water as pictures of how awesome God’s power is. But notice why they want this: so that everyone, even people who don’t follow God, would know who he is and respect him. The goal isn’t destruction; it’s revelation. When you face a hard situation, you can pray like this: “God, please act so clearly that everyone will see how great you are.”
Questions People Ask
What does ‘brushwood’ mean in Isaiah 64:2?
Brushwood refers to dry twigs or stubble that catch fire quickly. The Hebrew word ‘hamasim’ likely comes from the idea of crackling or breaking into pieces. It emphasizes the speed and intensity of God’s action.
Why does the verse mention water boiling?
Water boiling is a vivid image of how God’s presence would affect the world, like a pot set over an intense fire. It shows that nothing stays the same when God comes down. The heat of his power changes everything.
What does ‘make your name known’ mean here?
In the Bible, God’s ‘name’ represents his character, reputation, and power. Making his name known means revealing who he is so that people, even enemies, recognize him and respond with awe.
Is this verse about God being angry?
Partially. The fire imagery does reflect God’s judgment on evil, but the purpose is not simply punishment. The goal is that God’s name would be known, and that the nations would tremble, which can lead to repentance and worship.
How does Isaiah 64:2 fit with the rest of the chapter?
The chapter opens with a cry for God to tear the heavens and come down (verse 1). Verses 2-3 continue that prayer, remembering how God acted in the past. Then verses 4-6 shift to confession of sin. The whole chapter is a mix of desperate hope and honest repentance.
