Isaiah 4:3 promises that the people who survive God’s judgment on Jerusalem will be called holy, meaning they will belong to God and be set apart for him. The verse is a prophecy spoken by Isaiah, the eighth-century prophet who ministered in Judah, and it speaks to the faithful remnant who remain in Zion and Jerusalem after the nation’s sin has been dealt with.
It will happen, that he who is left in Zion, and he who remains in Jerusalem, shall be called holy, even everyone who is written among the living in Jerusalem…

What Isaiah 4:3 Means
The verse begins with “he who is left” and “he who remains,” two phrases that point to a remnant, the small group that outlasts a disaster. In Isaiah’s day, Jerusalem had been shaken by invasion and by the consequences of its own injustice. The prophet is saying that God will not simply end the story with ruin. A people will remain, and God will keep them.
The phrase “shall be called holy” is the center of the verse. To be holy in the Old Testament means to be set apart for God’s purposes and marked as his. Those who remain are not holy because they are impressive or because they earned it. They are holy because God has claimed them and cleansed them. The word “written among the living” adds a picture of a register or census, where God records the names of those who belong to him and to life.
The verse does not promise that every person in the city will be spared or that hardship will vanish. It describes a people who come through judgment and are identified as God’s own afterward. Read on its own, it is a statement of hope, but it depends on the cleansing that the surrounding verses describe.
The Context of Isaiah 4:3
Isaiah 4 belongs to the early chapters of the book of Isaiah, which open with a sharp indictment of Judah’s pride, idolatry and social injustice. The book is traditionally attributed to the prophet Isaiah, and its first audience was the people of Jerusalem and Judah. Chapter 4 follows judgment-laden material in chapters 2 and 3, and it turns the mood toward restoration. The verses just before describe a time of desperation, when men are scarce and women plead to be called by a man’s name for their protection and dignity.
Verses 4 through 6 explain how the remnant becomes holy. The Lord washes away the filth of Zion and purges the blood of Jerusalem by a spirit of justice and a spirit of burning, then covers the city with a cloud by day and a fire by night, plus a shelter from heat and storm. Seen in that setting, verse 3 is the hinge of the passage. Holiness is the result of God’s cleansing judgment, and the sheltering presence that follows is the evidence of it.

Isaiah 4:4
When the Lord shall have washed away the filth of the daughters of Zion, and shall have purged the blood of Jerusalem from within it, by the spirit of justice, and by the spirit of burning.

This verse, which follows directly, explains the means by which the Lord washes away the filth and purges the blood. Reading it alongside verse 3 shows that holiness comes through God’s judgment and cleansing rather than through the people’s own effort.
Isaiah 1:18
“Come now, and let us reason together,” says the LORD: “Though your sins be as scarlet, they shall be as white as snow. Though they be red like crimson, they shall be as wool.

Isaiah 1:18 offers a parallel picture of God making unclean people clean. It shows the same prophet’s conviction that God is willing and able to cleanse a sinful people and restore them to himself.
A Short Prayer From Isaiah 4:3
Lord, you see the places in my life that have been shaken and stripped bare. Thank you that you do not leave your people without hope. Wash away what is unclean in me, and let me belong to you in the way you describe in your word. When I feel small or overlooked, remind me that you know my name and have written it among the living. Let your presence cover me like a shelter, and help me live as one who is set apart for you. Amen.
