And according to the multitude
of thy tender mercies blot out my iniquity.
Wash me yet more from my iniquity,
and cleanse me from my sin.
For I know my iniquity, and my sin is always before me.
To thee only have I sinned, and have done evil before thee:
that thou mayst be justified in thy words
and mayst overcome when thou art judged.
For behold I was conceived in iniquities;
and in sins did my mother conceive me.
For behold thou hast loved truth:
the uncertain and hidden things of thy wisdom
thou hast made manifest to me.
Thou shalt sprinkle me with hyssop, and I shall be cleansed:
thou shalt wash me, and I shall be made whiter than snow.
To my hearing thou shalt give joy and gladness:
and the bones that have been humbled shall rejoice.
Turn away thy face from my sins,
and blot out all my iniquities.
Create a clean heart in me, O God:
and renew a right spirit within my bowels.
Cast me not away from thy face;
and take not thy holy spirit from me.
Restore unto me the joy of thy salvation,
and strengthen me with a perfect spirit.
I will teach the unjust thy ways:
and the wicked shall be converted to thee.
Deliver me from blood, O God, thou God of my salvation:
and my tongue shall extol thy justice.
O Lord, thou wilt open my lips:
and my mouth shall declare thy praise.
For if thou hadst desired sacrifice,
I would indeed have given it:
with burnt offerings thou wilt not be delighted.
A sacrifice to God is an afflicted spirit:
a contrite and humbled heart,
O God, thou wilt not despise.
Deal favourably, O Lord, in thy good will with Sion;
that the walls of Jerusalem may be built up.
Then shalt thou accept the sacrifice of justice,
oblations and whole burnt offerings:
then shall they lay calves upon thy altar.
-- Psalm 50 Douay-Rheims Bible
