Have mercy on me, O God, in your goodness; in the greatness of your compassion wipe out my offense. Thoroughly wash me from my guilt and of my sin cleanse me. For I acknowledge my offense, and my sin is before me always: "Against you only have I sinned, and done what is evil in your sight," That you may be justified in your sentence, vindicated when you condemn. Indeed, in guilt was I born, and in sin my mother conceived me; Behold, you are pleased with sincerity of heart, and in my inmost being you teach me wisdom. Cleanse me of sin with hyssop, that I may be purified; wash me, and I shall be whiter than snow. Let me hear the sounds of joy and gladness; the bones you have crushed shall rejoice. Turn away your face from my sins, and blot out all my guilt. A clean heart create for me, O God, a nd a steadfast spirit renew within me. Cast me not out from your presence, and your holy spirit take not from me. Give me back the joy of your salvation, and a willing spirit sustain in me. I will teach transgressors your ways, and sinners shall return to you. Free me from blood guilt, O Lord, my saving God; then my tongue shall revel in your justice. O Lord, open my lips, and my mouth shall proclaim your praise. For you are not pleased with sacrifices; should I offer a holocaust, you would not accept it. My sacrifice, O God, is a contrite spirit; a heart contrite and humbled, O God, you will not spurn. Be bountiful, O Lord, to Sion in your kindness by rebuilding the walls of Jerusalem; Then shall you be pleased with due sacrifices, burnt offerings and holocausts; then shall they offer up bullocks on your altar.
A partial indulgence is granted to the faithful, who with repentant heart recite the psalm Have mercy on me (Ps 50).
