Verse in Context
Scholars' Consensus
Commentators across traditions agree that David's lips are sealed by the weight of his sin. Matthew Henry observes that David had stopped the mouth of conscience with excuses, but now guilt shuts his mouth from praise. Barnes notes that the original Hebrew verb is future tense, expressing both a prayer and a confident expectation that God will open his lips by taking away guilt and filling the heart with the joy of pardon. Clarke adds that David could not praise God for pardon until he actually felt pardoned. Gill describes the lips as shut with shame and sorrow, only a discovery of pardoning grace can open them. The Cambridge Bible points out that the power to praise aright is itself God's gift, comparing David to a leper restored to fellowship. In short, the scholars agree: divine forgiveness precedes and enables human praise. The chain is clear, guilt silences, grace opens, and the mouth then naturally declares God's praise.
How settled is the interpretation?
Interpretive difficulty: Low
What is clear: David cannot praise God until God removes his guilt and restores the joy of salvation.
What Scholars Agree and Debate
| Topic | Agreed | Debated |
|---|---|---|
| The condition of David's lips | David's lips are shut because of guilt, shame, and sorrow over his sin. He cannot praise God until the barrier is removed. | Some commentators emphasize the immediate cause (shame and sorrow, as Wesley: 'My lips, Which are shut with shame and grief'), while others point to the deeper root (consciousness of sin and need for forgiveness, as Gill and Barnes). |
| The nature of the request | David asks God to take the initiative. Only divine forgiveness can open his mouth for praise. | Is the request primarily for the act of forgiveness itself (so that praise may follow), or for the spiritual enablement to praise even after forgiveness is assured? Barnes sees it as a confident expectation that God 'would' open his lips; Clarke says David could not praise until he felt pardoned. Both affirm that praise is God's gift. |
| Grammatical nuance: imperative vs future indicative | The Hebrew form can be read as either an imperative ('open') or a future indicative ('you will open'). Both readings are prayerful. | The Cambridge Bible renders it 'thou shalt open' and explains it as a confident statement: 'when thou openest.' The KJV renders it as a petition. The interpretive difference is slight, both emphasize God's action, but the future tense stresses assurance, while the imperative stresses need. |
Historical & Cultural Context
Psalm 51 anchors in one of the darkest episodes of David's life. The title places the psalm after Nathan the prophet confronted David over his adultery with Bathsheba and the arranged death of her husband Uriah (2 Samuel 11, 12). Calvin notes that David had sunk into a spiritual lethargy for over a year before Nathan's rebuke finally roused him. The psalm is David's raw, public confession, a penitential Psalm used by the church for centuries.
Verse 15 falls near the psalm's conclusion. In the preceding verses David prays for deliverance from bloodguiltiness (v.14). The word blood refers to Uriah's murder; David now calls it by its right name (Keil & Delitzsch). Only after pleading for cleansing does he ask for his lips to be opened. In ancient Israel, public worship involved spoken and sung praise. A person bearing unconfessed guilt was effectively excluded from full participation, much as a leper was separated from the congregation (Cambridge Bible compares the leper's restoration). David feels that his sin has sealed his mouth shut, he cannot join the songs of Zion until God restores him.
This verse also echoes a broader Old Testament pattern: God is the one who opens mouths. The Lord tells Moses, 'Who made man's mouth? … Isn't it I, Yahweh?' (Exodus 4:11). The prophet Ezekiel is promised, 'I will open your mouth' when he speaks for God (Ezekiel 3:27). David is not asking for permission to speak; he is asking for the power and desire to praise, which only a restored relationship with God can provide.
Textual Notes
The supplied commentaries note no significant textual variants for Psalm 51:15. The Hebrew verb form (future tense) has been understood either as an imperative ('open') or as a future indicative ('you will open'), as reflected in translations. The Cambridge Bible prefers the literal future rendering. This grammatical difference does not change the essential meaning: David depends on God to act, whether as a plea or a declaration of trust.
Reception History
Psalm 51 is one of the seven traditional Penitential Psalms, and verse 15 has been prayed by Christians preparing for worship and confession. In the early church, this psalm was associated with Lenten disciplines, as believers sought to approach God with broken hearts and receive pardon before offering praise. The verse has also been set to music in hymns that express the joy of restored communion. Across traditions, Catholic, Orthodox, Protestant, this prayer has reminded worshippers that praise begins not with human readiness but with divine grace that opens closed mouths.
Preaching This Verse
Three-point outline
- Guilt silences praise. David's lips are shut by shame and sorrow. Sin does not merely make us feel bad; it stops our mouths from declaring God's goodness. Until we face our sin honestly, our songs ring hollow.
- Only God can open our lips. David prays for something only God can give. The verb is future tense, 'you will open', blending request with trust. Forgiveness is not a human achievement but a divine gift that restores our voice.
- Praise is the natural response to forgiveness. When God opens our lips, the mouth declares his praise. Praise is not a duty we force; it flows from a heart that knows it has been pardoned.
Five-point outline
- The problem: a closed mouth (shame, guilt, spiritual paralysis)
- The prayer: 'Open my lips' (a cry for grace)
- The power: God alone can remove the barrier (divine initiative)
- The promise: 'My mouth will declare your praise' (confidence in God's response)
- The purpose: praise that teaches others (v.13, 'then I will teach transgressors your ways')
Illustration hooks
- A person who has wronged a friend and cannot bring themselves to speak, feeling the weight of silence, until the friend extends forgiveness and the conversation flows again.
- A worship leader who finds their own singing hollow after a season of hidden sin, they need personal restoration before they can lead others authentically.
- The experience of a church that prays this verse before the confession of sin in a service, acknowledging that only God’s pardon can truly open their mouths to praise.
Questions your congregation is asking
- Why do I sometimes feel unable to praise God, even when I want to?
- Does God need to 'open my lips' every day, or is this a one-time prayer?
- How can I tell the difference between guilt that is from God (leading to repentance) and guilt that is from the enemy (leading to silence)?
Leading a Discussion
This verse cuts to the heart of worship. It reminds us that praise is not merely something we muster up; it is a response to God's prior work of grace. David knew that his sin had sealed his mouth, and only God could break the seal. As you discuss, keep the focus on how God's forgiveness frees us to praise.
Discussion questions
- What does David ask for in this verse? Why does he need to ask God to open his lips?
- Look at the surrounding context (vv.14, 17). How does the theme of sacrifice and a broken heart connect to this prayer for opened lips?
- Barnes says the verb is future tense, 'you will open my lips.' How does that affect the way we read the verse? Is it a plea, a statement of faith, or both?
- In your own experience, has guilt ever silenced your praise? What helped you find your voice again?
- Cross-reference Exodus 4:11 and Ezekiel 3:27. What does it mean that God is the one who makes mouths and opens them?
- How does this verse challenge the idea that worship is primarily our effort or offering?
- What would it look like for your group or church to pray this verse honestly before a time of worship?

What the Commentators Say
9 public-domain commentaries, condensed into plain language.
Adam Clarke's Commentary Methodist/Wesleyan 1826
Clarke stresses that genuine praise for pardon cannot precede the actual experience of being pardoned. The heart first believes unto righteousness, and only then does God grant peace that enables the tongue to confess and praise the Redeemer.
Barnes' Notes on the Bible Protestant 1832
Barnes reads "open my lips" as a plea for God to remove guilt and give the speaker the inner assurance that sin is forgiven. Until that burden lifts, praise cannot come. Once pardon arrives, praise follows as the natural, joyful overflow.
Geneva Bible Notes Reformed 1599
The Geneva note highlights that even the ability to speak God's praise must come from God himself. The psalmist cannot open his own lips; he must ask the Lord to do it, and only then will his mouth show forth praise. True worship begins with divine enablement.
Gill's Exposition of the Bible Baptist 1748
Gill explains that the guilt of sin had shut the psalmist's lips, especially for praise and thanksgiving. Only a clear sense of pardoning grace could open them. His prayer for opened lips is a plea for that forgiveness, which alone enables joyful praise.
Jamieson-Fausset-Brown Commentary Protestant 1871
JFB explains that when the psalmist asks for his lips to be opened, the request is tied directly to the removal of guilt. Until that burden is lifted, praise and confession remain blocked, so the opening of the lips follows the clearing of the conscience.
Keil & Delitzsch OT Commentary Protestant 1876
Keil and Delitzsch stress that David refuses to soften his guilt, naming it plainly as bloodshed. Yet mercy has already lifted him; he prays not for forgiveness as something new but for its completion. God takes no pleasure in sacrifices; what he truly accepts is a spirit broken and crushed.
Lange's Commentary Reformed 1857
Lange stresses that David's confession "against Thee only" does not dismiss his wrongs against Bathsheba and Uriah. Instead it declares sin's essential nature: every offense is ultimately against God. For Lange, this is an objective theological truth, not merely David's subjective feeling, and it drives the need for divine grace alone.
Matthew Henry's Commentary Reformed/Presbyterian 1710
Henry notes that David finally stops excusing himself with the technicality that he did not kill Uriah with his own hand. Convinced he is the real murderer, he cries to God as the God of salvation for deliverance from the guilt of blood.
Wesley's Explanatory Notes Methodist/Wesleyan 1754
My lips - Which are shut with shame and grief.
