Isaiah 6:5

Then said I, Woe is me! for I am undone; because I am a man of unclean lips, and I dwell in the midst of a people of unclean lips: for mine eyes have seen the King, the Lord of hosts.

Isaiah 6:5 (KJV)

Context

Isaiah 6 opens with a vision granted to the prophet in the year King Uzziah died. Isaiah sees the Lord seated on a throne, high and lifted up, with the train of His robe filling the temple. Seraphim stand above Him, calling to one another, “Holy, holy, holy, is the LORD of hosts: the whole earth is full of his glory.” The doorposts shake at their voices, and the house fills with smoke. In that overwhelming setting, Isaiah cries out the words of this verse, confessing his ruin before the holy God.

Meaning

Isaiah’s cry, “Woe is me!” expresses deep distress and a sudden, painful awareness of his own sinfulness. The word “undone” conveys a sense of being destroyed or cut off, reflecting his realization that no unclean person can stand before the holy God. His confession focuses on his lips, the instrument of speech, because he has just heard the seraphim declare God’s holiness. The contrast between God’s purity and his own impurity is overwhelming.

Isaiah also identifies with his people, acknowledging that he dwells among a people of unclean lips. This shows the corporate dimension of sin: the prophet is not isolated in his guilt but shares in the condition of the nation he represents. His words highlight the need for repentance and a turning back to God.

The climax of the verse is the reason for his despair: “for mine eyes have seen the King, the LORD of hosts.” The title “LORD of hosts” emphasizes God’s sovereign power over all heavenly and earthly armies. A true vision of God’s holiness leads to a profound sense of personal unworthiness. This is not an abstract doctrine but a reality that confronts and convicts.

Biblical connections

John 12:41 states that Isaiah saw Jesus’ glory and spoke of Him, indicating that the King Isaiah saw was the pre-incarnate Christ. This New Testament connection confirms that the vision of God’s glory in Isaiah 6 points directly to the person of Christ.

Application

Isaiah’s response reminds believers that in the presence of God’s holiness, we are all exposed and fall short. It teaches us to recognize our sinfulness, confess our inadequacies, and approach God with humility and reverence. The following verses describe how one of the seraphim purifies Isaiah’s lips with a burning coal from the altar, symbolizing forgiveness and cleansing. This action signifies God’s grace and willingness to forgive and transform those who humbly come before Him in repentance.

Reflection

Isaiah’s encounter with the King brings him to a place of humility and awe. His confession is not the end but the beginning of God’s gracious work. The same God who confronts us with our sin also provides the means of cleansing, offering forgiveness and transformation to all who repent.
