Chapter Overview
Summary
Psalm 51 (MT) / Psalm 50 (LXX) is the Psalter's foundational penitential-psalm — the Miserere — composed (per its superscription) by David after Nathan's confrontation over Bathsheba and Uriah (2 Sam 12). No other psalm shaped Western liturgical confession-theology more: the Latin Miserere mei Deus (v. 1) gave its name to an entire genre of polyphonic-composition (Allegri, Palestrina, Lotti). Its radical anthropological confession ('I was brought forth in iniquity, and in sin did my mother conceive me,' v. 5) became the scriptural foundation for Augustine's original-sin doctrine. Its 'create in me a clean heart' (v. 10) uses the verb bara — the creation-verb of Genesis 1:1 — applying it to the human-heart: moral-regeneration is a new-creation act of God.
Notable Variants
51:4 'against you only have I sinned' → Romans 3:4 citation ('that you may be justified in your words'); 51:5 'conceived in sin' as Augustinian original-sin foundation; 51:10 'create in me a clean heart' deploying bara/ktizō creation-verb for spiritual-regeneration; 51:16–17 'sacrifices of God are a broken spirit' as prophetic-ethical critique of ritual.
Structural Notes
MT Ps 51 = LXX Ps 50. 21 verses (MT/LXX), 19 verses (English). One of the seven penitential psalms.
For the director of music. A psalm of David.
Superscription tying the psalm to Nathan's confrontation of David after Bathsheba and Uriah (2 Sam 11–12) tracks MT. The historical-narrative-to-liturgical-psalm movement makes this the Bible's clearest example of particular-sin confession becoming universal-liturgical-template.
after he had gone in to Bathsheba. When Nathan the prophet came to him,
Superscription continues tracks MT.
Be gracious to me, God, according to your faithful love; according to the abundance of your compassion, wipe out my rebellions.
'Have mercy on me, O God, according to your steadfast love' tracks MT. 'MISERERE MEI DEUS.' The Latin Vulgate Miserere mei, Deus — the opening words of the psalm — became the title of one of Western Christendom's most-set liturgical texts (Allegri, Palestrina, Lotti, Scarlatti, Lassus).
Wash me thoroughly from my guilt, and from my sin cleanse me.
'Wash me thoroughly from my iniquity' tracks MT.
For my rebellions — I know them, and my sin is before me continually.
'For I know my transgressions, and my sin is ever before me' tracks MT. Self-recognition-of-sin as confession-prerequisite.
Against you — you alone — have I sinned, and done what is evil in your sight, so that you are justified when you speak and blameless when you judge.
Masoretic (WLC)
לְךָ לְבַדְּךָ חָטָאתִי וְהָרַע בְּעֵינֶיךָ עָשִׂיתִי לְמַעַן תִּצְדַּק בְּדָבְרֶךָ תִּזְכֶּה בְשָׁפְטֶךָ
Against you, you only, have I sinned and done what is evil in your sight, so that you may be justified in your words and blameless in your judgment
Septuagint (LXX)
σοὶ μόνῳ ἥμαρτον καὶ τὸ πονηρὸν ἐνώπιόν σου ἐποίησα ὅπως ἂν δικαιωθῇς ἐν τοῖς λόγοις σου καὶ νικήσῃς ἐν τῷ κρίνεσθαί σε
Against you only have I sinned and done evil before you, that you may be justified in your words and prevail when you are judged
ROMANS 3:4 CITATION. Paul cites this verse verbatim from the LXX at Romans 3:4: 'Let God be true though every man is a liar, as it is written: That you may be justified in your words, and will prevail when you are judged' (hopōs an dikaiōthēs en tois logois sou kai nikēseis en tō krinesthai se). Paul deploys the psalmic text to defend God's faithfulness against the charge that Israel's unbelief undermines divine-reliability: even human-sin has God's truthfulness as its foil.
'AGAINST YOU ONLY.' David's confession — though his sin was against Bathsheba and Uriah — emphasizes that all sin is ultimately against God. This theological-reduction locates divine-offense as the universal-element of sin (cf. Gen 39:9 Joseph: 'how could I do this great wickedness and SIN AGAINST GOD'). The vertical dimension of sin (against God) contains and transcends the horizontal (against neighbor), without canceling the latter.
'WHEN YOU ARE JUDGED' (en tō krinesthai se). The LXX's passive/middle reading — 'when you are judged' — differs from MT's active 'in your judging.' Paul follows the LXX. The notion that God is 'judged' (by those who would accuse him of injustice) creates space for theodicy-discussion: God is justified in the court-of-theodicy-critics.
Look — in guilt I was brought forth, and in sin my mother conceived me.
Masoretic (WLC)
הֵן־בְּעָווֹן חוֹלָלְתִּי וּבְחֵטְא יֶחֱמַתְנִי אִמִּי
Behold, I was brought forth in iniquity, and in sin did my mother conceive me
Septuagint (LXX)
ἰδοὺ γὰρ ἐν ἀνομίαις συνελήμφθην καὶ ἐν ἁμαρτίαις ἐκίσσησέν με ἡ μήτηρ μου
For behold, I was conceived in iniquities, and in sins my mother desired me
ORIGINAL-SIN TEXT. Augustine's doctrine of original-sin (De peccatorum meritis et remissione, De natura et gratia, Confessions) rests substantially on this verse. The confession — 'I was conceived in iniquities' — describes not merely David's particular origin but the universal human-condition: sin-enmeshment precedes personal-choice. Romans 5:12–21 ('as sin came into the world through one man') and Ephesians 2:3 ('by nature children of wrath') extend the theology.
'MY MOTHER DESIRED ME' (ekissēsen me). The LXX's 'desired/craved' (from kissaō, a rare verb for maternal-longing) differs from the MT's simpler 'conceived' (yechematni). The LXX rendering emphasizes the mother's desire-for-the-child as the context within which the sinful-nature emerges — not blaming the mother, but showing sin-penetration into the most-tender desires.
Look — you desire truth in the innermost being; so in the hidden depths, teach me wisdom.
'Behold, you delight in truth in the inward being' tracks MT. Divine-demand for inward-truth — anticipating John 4:24's 'worship in spirit and truth.'
Purify me with hyssop and I will be clean; wash me and I will be whiter than snow.
'Purge me with hyssop, and I shall be clean' tracks MT. Hyssop — the purification-plant of Leviticus 14 (leper-cleansing) and Exodus 12:22 (Passover blood-application). John 19:29's hyssop-stalk at the crucifixion connects Christ's death to this purification-chain.
Let me hear joy and gladness; let the bones you have crushed rejoice.
'Let me hear joy and gladness; let the bones that you have broken rejoice' tracks MT.
Hide your face from my sins, and wipe out all my guilt.
'Hide your face from my sins' tracks MT. The hide-your-face-from-sins petition — inversion of the usual 'do not hide your face' prayer.
Create in me a clean heart, God, and renew a steadfast spirit within me.
Masoretic (WLC)
לֵב טָהוֹר בְּרָא־לִי אֱלֹהִים וְרוּחַ נָכוֹן חַדֵּשׁ בְּקִרְבִּי
Create in me a clean heart, O God, and renew a right spirit within me
Septuagint (LXX)
καρδίαν καθαρὰν κτίσον ἐν ἐμοί ὁ θεός καὶ πνεῦμα εὐθὲς ἐγκαίνισον ἐν τοῖς ἐγκάτοις μου
Create in me a clean heart, O God, and renew a right spirit in my inward parts
CREATION-VERB APPLIED TO REGENERATION. 'CREATE' (bara / ktison) is the same verb used at Genesis 1:1 ('in the beginning God CREATED the heavens and earth'). Reserved almost exclusively for divine-action in the Hebrew Bible, bara here names moral-spiritual regeneration as a creation-act of God. The sinner cannot self-reform his heart; only the creator-God can create a clean heart.
'RENEW' (encainison). The 'new' (kainos) root — the LXX's verb here — anticipates 2 Cor 5:17 ('if anyone is in Christ, new creation' — kainē ktisis) and Ezekiel 36:26 ('I will give you a new heart and put a new spirit within you'). The new-covenant regeneration theology begins here and receives full development in Ezekiel and Paul.
'CLEAN HEART' (kardian katharan). Matthew 5:8 ('blessed are the PURE IN HEART, for they shall see God' — hoi katharoi tē kardia) echoes this psalm's purification-petition Christologically.
Do not cast me away from your presence, and do not take your Holy Spirit from me.
'Cast me not away from your presence, and take not your Holy Spirit from me' tracks MT. HOLY SPIRIT LANGUAGE — one of the OT's rare explicit 'Holy Spirit' (ruach qodshecha / pneumatos hagiou) references (also Isa 63:10–11). The Davidic fear that the Spirit might depart (as with Saul, 1 Sam 16:14) is the personal-specific context.
Restore to me the joy of your salvation, and sustain me with a willing spirit.
'Restore to me the joy of your salvation' tracks MT. Joy-of-salvation — the experiential-recovery petition. Uphold me with a 'willing spirit' (pneumati hēgemonikō / princely-spirit) for governing-one's-life.
Then I will teach rebels your ways, and sinners will return to you.
'Then I will teach transgressors your ways' tracks MT. Forgiveness-produces-evangelism — the restored-sinner's teaching-vocation.
Deliver me from bloodguilt, God — God of my salvation! My tongue will sing aloud of your righteousness.
'Deliver me from bloodguilt, O God' tracks MT. 'Bloodguilt' (damim / haimatōn) — Uriah's-blood on David's hands.
Lord, open my lips, and my mouth will declare your praise.
'O Lord, open my lips, and my mouth will declare your praise' tracks MT. This opening-of-lips petition became the traditional introit for Christian morning-prayer (Liturgy of the Hours) — the daily-office opens each day with this line.
For you do not desire sacrifice — I would give it; you take no pleasure in burnt offering.
Masoretic (WLC)
כִּי לֹא־תַחְפֹּץ זֶבַח וְאֶתֵּנָה עוֹלָה לֹא תִרְצֶה
For you will not delight in sacrifice, or I would give it; you will not be pleased with a burnt offering
Septuagint (LXX)
ὅτι εἰ ἠθέλησας θυσίαν ἔδωκα ἄν ὁλοκαυτώματα οὐκ εὐδοκήσεις
For if you had desired sacrifice, I would have given it; you will not be pleased with whole burnt offerings
PROPHETIC-ETHICAL CRITIQUE OF RITUAL. This verse stands in the biblical family of sacrifice-critiques alongside 1 Sam 15:22 ('to obey is better than sacrifice'), Isa 1:11–17, Amos 5:21–24, Hos 6:6 ('I desire steadfast love and not sacrifice'), Micah 6:6–8, and Ps 40:6–8. The critique is not of the sacrificial-system per se but of sacrifice-without-contrition. Hebrews 10:5–10 picks up the family of texts to argue Christ's obedient self-offering supersedes the Levitical system.
The sacrifices God accepts are a broken spirit; a broken and crushed heart — God, you will not despise.
'The sacrifices of God are a broken spirit; a broken and contrite heart, O God, you will not despise' tracks MT. BROKEN-SPIRIT SACRIFICE. The 'broken and contrite heart' (lev-nishbar ve-nidkeh / kardian syntetrimmenēn kai tetapeinōmenēn) defines the true sacrifice. Matthew 5:3 ('blessed are the poor in spirit') and 5:4 ('blessed are those who mourn') articulate the Beatitudes from this penitential anthropology. Isaiah 57:15 and 66:2 develop the broken-and-contrite theology as God's preferred-dwelling among humans.
Do good to Zion in your favor; build up the walls of Jerusalem.
'Do good to Zion in your good pleasure; build up the walls of Jerusalem' tracks MT. The editorial-addition (perhaps post-exilic) extends the Davidic-individual penitence to national-corporate petition — appropriate for Second Temple liturgical use.
Then you will delight in righteous sacrifices — burnt offering and whole offering; then bulls will be offered on your altar.
'Then will you delight in right sacrifices, in burnt offerings and whole burnt offerings; then bulls will be offered on your altar' tracks MT. The editorial close — restoring the temple-cultus in eschatological-fulfillment — sits in apparent tension with v. 18. Resolution: v. 18 critiques sacrifice-alone; v. 21 envisions the restored-cultus in which ethical-contrition and ritual-sacrifice rejoin.
