Psalms 51

For the Chief Musician. A Psalm by David, when Nathan the prophet came to him, after he had gone in to Bathsheba.

Have mercy on me, God, according to your loving kindness. According to the multitude of your tender mercies, blot out my transgressions.

Wash me thoroughly from my iniquity. Cleanse me from my sin.

For I know my transgressions. My sin is constantly before me.

Against you, and you only, I have sinned, and done that which is evil in your sight, so you may be proved right when you speak, and justified when you judge.

Behold, I was born in iniquity. My mother conceived me in sin.

Behold, you desire truth in the inward parts. You teach me wisdom in the inmost place.

Purify me with hyssop, and I will be clean. Wash me, and I will be whiter than snow.

Let me hear joy and gladness, that the bones which you have broken may rejoice.

Hide your face from my sins, and blot out all of my iniquities.

Create in me a clean heart, O God. Renew a right spirit within me.

Don’t throw me from your presence, and don’t take your Holy Spirit from me.

Restore to me the joy of your salvation. Uphold me with a willing spirit.

Then I will teach transgressors your ways. Sinners will be converted to you.

Deliver me from the guilt of bloodshed, O God, the God of my salvation. My tongue will sing aloud of your righteousness.

Lord, open my lips. My mouth will declare your praise.

For you don’t delight in sacrifice, or else I would give it. You have no pleasure in burnt offering.

The sacrifices of God are a broken spirit. O God, you will not despise a broken and contrite heart.

Do well in your good pleasure to Zion. Build the walls of Jerusalem.

Then you will delight in the sacrifices of righteousness, in burnt offerings and in whole burnt offerings. Then they will offer bulls on your altar.

Overview. This chapter is a profound personal lament and plea for mercy in the wake of grave sin, expressing deep sorrow, self-awareness of guilt, and dependence on God’s steadfast love. It stands as one of the penitential psalms, giving voice to a soul crushed under the weight of transgression yet reaching toward cleansing and restoration through divine grace alone.

Flow.

The psalm opens with urgent petitions for mercy, rooted not in human merit but in God’s abundant lovingkindness and tender mercies (vv. 1–2).
The confession intensifies as the psalmist acknowledges the persistent presence of sin and affirms God’s righteousness in judgment, even when that judgment falls upon the sinner (vv. 3–4).
A turn inward follows, recognizing the depth of human corruption from birth and God’s desire for truth within (vv. 5–6), leading to vivid imagery of purification and the longing for restored joy (vv. 7–9).
The petitions shift toward spiritual renewal and the reinstatement of communion with God, culminating in the promise to proclaim God’s goodness if restored (vv. 10–14), followed by a recognition that true worship flows from repentance, not ritual (vv. 15–17).
The psalm closes with intercession for Zion, linking personal restoration to the well-being of God’s people and the renewal of proper worship (vv. 18–19).

Connections. Following Psalm 50, which emphasizes God’s demand for integrity and true worship over empty ritual, this psalm personalizes that call by modeling the repentance God truly desires. The focus on inward truth and contrition directly responds to the warnings of the preceding psalm. The longing for a clean heart and renewed spirit prepares the way for Psalm 52, where the fate of the deceitful contrasts sharply with the hope of the repentant, and where trust in God’s steadfast love remains the anchor.

What it teaches. The psalm bears witness to the reality of original sin (WCF 6.3), the absolute necessity of inward renewal (Ezek. 36:26; cf. WCF 13.1), and the primacy of God’s mercy in justification. It teaches that forgiveness flows from divine lovingkindness, not human sacrifice (WCF 11.1), and that true worship arises from a broken spirit and contrite heart (BC Article 23). The plea for the Holy Spirit’s presence (v. 11) reflects the Reformed understanding of sanctification as God’s work within (WCF 13.3), while the link between personal renewal and corporate restoration echoes the covenantal unity of individual and community in God’s redemptive purpose (HC LD 31).

Apply. When burdened by sin, approach God not with excuses or offerings, but with honesty and expectation of mercy grounded in his character.
