Psalm 51, from the Book of Common Prayer

Psalm 51 
Miserere mei, Deus

 1 Have mercy on me, O God, according to your loving-kindness; *
    in your great compassion blot out my offenses.
 2 Wash me through and through from my wickedness *
    and cleanse me from my sin.
 3 For I know my transgressions, *
    and my sin is ever before me.
 4 Against you only have I sinned *
    and done what is evil in your sight.
 5 And so you are justified when you speak *
    and upright in your judgment
 6 Indeed, I have been wicked from my birth, *
    a sinner from my mother's womb.
 7 For behold, you look for truth deep within me, *
    and will make me understand wisdom secretly.
 8 Purge me from my sin, and I shall be pure; *
    wash me, and I shall be clean indeed.
 9 Make me hear of joy and gladness, *
    that the body you have broken may rejoice.
10 Hide your face from my sins *
    and blot out all my iniquities.
11 Create in me a clean heart, O God, *
    and renew a right spirit within me.
12 Cast me not away from your presence *
    and take not your holy Spirit from me.
13 Give me the joy of your saving help again *
    and sustain me with your bountiful Spirit.
14 I shall teach your ways to the wicked, *
    and sinners shall return to you.
15 Deliver me from death, O God, *
    and my tongue shall sing of your righteousness, O God of my salvation.
16 Open my lips, O Lord, *
    and my mouth shall proclaim your praise.
17 Had you desired it, I would have offered sacrifice; *
    but you take no delight in burnt-offerings.
18 The sacrifice of God is a troubled spirit; *
    a broken and contrite heart, O God, you will not despise.
