Psalm 50 begins with a plea for mercy. It does not excuse wrongdoing or declare that the sinner is beyond God’s help. It asks for cleansing, a renewed heart and restored joy.
The complete prayer
The following is an explanatory English rendering of the Church Slavonic prayer text, without the superscription. It is not an official liturgical translation.
Have mercy on me, O God, according to Your great mercy; according to the abundance of Your compassion, cleanse my lawlessness. Wash me thoroughly from my lawlessness and cleanse me from my sin. For I know my lawlessness, and my sin is always before me. Against You alone have I sinned and done evil before You, that You may be justified in Your words and prevail when You judge.
For I was conceived in lawlessness, and in sins my mother bore me. You have loved truth; You have revealed to me the hidden mysteries of Your wisdom. Sprinkle me with hyssop, and I shall be clean; wash me, and I shall be whiter than snow. Let me hear joy and gladness; the humbled bones shall rejoice. Turn Your face from my sins and cleanse all my lawlessness.
Create a clean heart in me, O God, and renew a right spirit within me. Do not cast me away from Your presence, and do not take Your Holy Spirit from me. Restore to me the joy of Your salvation and strengthen me with Your sovereign Spirit. I shall teach the lawless Your ways, and the ungodly shall return to You.
Deliver me from bloodguilt, O God, God of my salvation, and my tongue shall rejoice in Your righteousness. Lord, open my lips, and my mouth shall declare Your praise. If You had desired sacrifice, I would have given it; You take no delight in burnt offerings. A sacrifice to God is a broken spirit; God will not despise a broken and humble heart.
In Your good pleasure, Lord, do good to Zion, and let the walls of Jerusalem be built. Then You will accept a sacrifice of righteousness, offerings and whole burnt offerings; then they will offer bulls upon Your altar.
Psalm 50 or Psalm 51?
The Church Slavonic and Greek numbering calls it Psalm 50. Most English Bibles following Hebrew numbering call it Psalm 51. The different number does not identify a different prayer.
The setting of repentance
The superscription associates the psalm with Nathan’s confrontation of David after the episode involving Bathsheba. Recognition of responsibility is central. Confessing sin before God does not erase harm to people or the need for whatever restitution remains possible.
The images
Hyssop recalls an Old Testament rite of purification. Creating a clean heart asks for renewal, not merely relief from an unpleasant feeling of guilt. Opened lips express the recovery of praise.
A humble heart and hope
A contrite heart is not a demand for self-destruction. Joy and hope stand beside confession of sin. After reading, consider a concrete response: returning what is owed, apologising or ending a dishonest practice. Reading the psalm does not replace confession or reconciliation.
More than regret about consequences
Repentance differs from wanting shame to disappear quickly. Someone may regret that a lie was exposed while still considering deception acceptable. The psalm asks for something deeper: renewal of the heart from which decisions come. In practice, begin by distinguishing what you did, whom it harmed, and what now depends on you. You need not catalogue every possible fault. The important thing is not to hide a particular responsibility behind general observations about everybody being imperfect.
If you passed on an unverified rumour, for example, concern about your own reputation is not enough. Stop repeating it and correct the false account with those who heard it. Do not then require the injured person to comfort you immediately or declare the matter forgotten. Repair aims to reduce harm, not to secure a convenient ending to the story for the person who caused it. Prayer can sustain that difficult honesty without bypassing it.
A clean heart and restored joy
The text places cleansing beside the recovery of joy. This matters to someone who imagines repentance as a duty to feel continually worse. Asking for renewal holds out hope that life can change. You do not have to manufacture tears to demonstrate sincerity. An honest acknowledgement may be spoken calmly, with feelings arriving later. Their intensity cannot replace the truth of what you acknowledge or your willingness to act differently. Neither emotional numbness nor strong emotion should become the sole measure of prayer.
Reading unfamiliar images
Purification, sacrifice, and the rebuilding of Jerusalem belong to the biblical world. Do not turn every detail into a household procedure: mentioning hyssop does not instruct you to find a plant for a domestic cleansing ritual. Establish what a word means in the psalm before reading a commentary. Keep an accessible translation nearby and note a question when a literal reading is confusing. A private guess does not have to become a rule imposed on the family.
Preparing for confession without blaming yourself for everything
After reading, briefly note matters for which you really are responsible. Distinguish your own conduct from someone else's actions and from a misfortune outside your control. Being unable to prevent every difficulty faced by a loved one is not identical to deliberately refusing help. If the distinction is hard to make, explain the circumstances to a priest, not merely an accusing conclusion about yourself. The psalm gives language for seeking mercy, but does not replace careful consideration of an actual situation.
End the reflection by choosing a manageable action instead of prolonging an endless internal trial. Returning an item, correcting an error, or offering a quiet apology does not buy God's forgiveness. These actions express the seriousness of asking for renewal and help keep repentance from becoming only the repetition of familiar words.
