When it is said
Orthodox Christians say this psalm in their morning prayers and again as they prepare for Holy Communion.
In church it is read every day at Matins, the Third Hour and Compline, and it is part of the service of confession.
At the Divine Liturgy the deacon and the priest say it together while the altar is censed, just before the procession called the Great Entrance.
Anyone may pray it at any time, and above all after a sin.
Where it comes from
Author by tradition
Written after David’s sin
The psalm’s Hebrew heading says David wrote it after the prophet Nathan came to him. David had taken Bathsheba, the wife of Uriah, for himself and had Uriah killed. When Nathan confronted him, David confessed that he had sinned against the Lord, and Nathan told him that the Lord had taken his sin away.
Psalm 51 (its heading); 2 Samuel 12:9-13
St Athanasius’s advice
St Athanasius of Alexandria wrote to a man named Marcellinus about which psalm to pray in which situation. For someone who has sinned, feels ashamed, repents and asks for mercy, he gave this one, because it holds the words of confession and repentance.
What the words mean
Why the words differ from your Bible
Orthodox books follow the Greek Bible, which numbers this psalm 50, and in a few lines the Greek differs from the Hebrew behind most English Bibles. The King James Version follows the Hebrew and has “uphold me with Thy free spirit”, while the Greek speaks of a guiding Spirit. The plain wording here follows the Greek.
Hyssop
Hyssop is a plant that grows out of walls. Under the Law of Moses, a priest dipped hyssop in blood and sprinkled a person healed of leprosy seven times, then declared him clean. In the psalm, David looks to God Himself to sprinkle him clean.
Leviticus 14:4-7; 1 Kings 4:33
The Scripture in it
Have mercy on me, O God, according to Your loving devotion; according to Your great compassion, blot out my transgressions. Wash me clean of my iniquity and cleanse me from my sin. For I know my transgressions, and my sin is always before me. Against You, You only, have I sinned and done what is evil in Your sight, so that You may be proved right when You speak and blameless when You judge. Surely I was brought forth in iniquity; I was sinful when my mother conceived me. Surely You desire truth in the inmost being; 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; let the bones You have crushed rejoice. Hide Your face from my sins and blot out all my iniquities. Create in me a clean heart, O God, and renew a right spirit within me. Cast me not away from Your presence; take not Your Holy Spirit from me. Restore to me the joy of Your salvation, and sustain me with a willing spirit. Then I will teach transgressors Your ways, and sinners will return to You. Deliver me from bloodguilt, O God, the God of my salvation, and my tongue will sing of Your righteousness. O Lord, open my lips, and my mouth will declare Your praise. For You do not delight in sacrifice, or I would bring it; You take no pleasure in burnt offerings. The sacrifices of God are a broken spirit; a broken and a contrite heart, O God, You will not despise. In Your good pleasure, cause Zion to prosper; build up the walls of Jerusalem. Then You will delight in righteous sacrifices, in whole burnt offerings; then bulls will be offered on Your altar.

In Greek
Ἐλέησόν με, ὁ Θεός, κατὰ τὸ μέγα ἔλεός σου καὶ κατὰ τὸ πλῆθος τῶν οἰκτιρμῶν σου ἐξάλειψον τὸ ἀνόμημά μου·
ἐπὶ πλεῖον πλῦνόν με ἀπὸ τῆς ἀνομίας μου καὶ ἀπὸ τῆς ἁμαρτίας μου καθάρισόν με.
ὅτι τὴν ἀνομίαν μου ἐγὼ γινώσκω, καὶ ἡ ἁμαρτία μου ἐνώπιόν μού ἐστι διαπαντός.
σοὶ μόνῳ ἥμαρτον καὶ τὸ πονηρὸν ἐνώπιόν σου ἐποίησα, ὅπως ἂν δικαιωθῇς ἐν τοῖς λόγοις σου, καὶ νικήσῃς ἐν τῷ κρίνεσθαί σε.
ἰδοὺ γὰρ ἐν ἀνομίαις συνελήφθην, καὶ ἐν ἁμαρτίαις ἐκίσσησέ με ἡ μήτηρ μου.
ἰδοὺ γὰρ ἀλήθειαν ἠγάπησας, τὰ ἄδηλα καὶ τὰ κρύφια τῆς σοφίας σου ἐδήλωσάς μοι.
ῥαντιεῖς με ὑσσώπῳ, καὶ καθαρισθήσομαι, πλυνεῖς με, καὶ ὑπὲρ χιόνα λευκανθήσομαι.
ἀκουτιεῖς μοι ἀγαλλίασιν καὶ εὐφροσύνην, ἀγαλλιάσονται ὀστέα τεταπεινωμένα.
ἀπόστρεψον τὸ πρόσωπόν σου ἀπὸ τῶν ἁμαρτιῶν μου καὶ πάσας τὰς ἀνομίας μου ἐξάλειψον.
καρδίαν καθαρὰν κτίσον ἐν ἐμοί, ὁ Θεός, καὶ πνεῦμα εὐθὲς ἐγκαίνισον ἐν τοῖς ἐγκάτοις μου.
μὴ ἀποῤῥίψῃς με ἀπὸ τοῦ προσώπου σου καὶ τὸ πνεῦμά σου τὸ ἅγιον μὴ ἀντανέλῃς ἀπ᾿ ἐμοῦ.
ἀπόδος μοι τὴν ἀγαλλίασιν τοῦ σωτηρίου σου καὶ πνεύματι ἡγεμονικῷ στήριξόν με.
διδάξω ἀνόμους τὰς ὁδούς σου, καὶ ἀσεβεῖς ἐπὶ σὲ ἐπιστρέψουσι.
ρῦσαί με ἐξ αἱμάτων, ὁ Θεὸς ὁ Θεὸς τῆς σωτηρίας μου· ἀγαλλιάσεται ἡ γλῶσσά μου τὴν δικαιοσύνην σου.
Κύριε, τὰ χείλη μου ἀνοίξεις, καὶ τὸ στόμα μου ἀναγγελεῖ τὴν αἴνεσίν σου.
ὅτι εἰ ἠθέλησας θυσίαν, ἔδωκα ἄν· ὁλοκαυτώματα οὐκ εὐδοκήσεις.
θυσία τῷ Θεῷ πνεῦμα συντετριμμένον, καρδίαν συντετριμμένην καὶ τεταπεινωμένην ὁ Θεὸς οὐκ ἐξουδενώσει.
ἀγάθυνον, Κύριε, ἐν τῇ εὐδοκίᾳ σου τὴν Σιών, καὶ οἰκοδομηθήτω τὰ τείχη ῾Ιερουσαλήμ·
τότε εὐδοκήσεις θυσίαν δικαιοσύνης, ἀναφορὰν καὶ ὁλοκαυτώματα· τότε ἀνοίσουσιν ἐπὶ τὸ θυσιαστήριόν σου μόσχους.
