Psalm 51:1-10

Have mercy upon me, O God, according to thy lovingkindness:
According unto the multitude of thy tender mercies blot out my transgressions.
Wash me throughly from mine iniquity,
And cleanse me from my sin.
For I acknowledge my transgressions:
And my sin is ever before me.
Against thee, thee only, have I sinned, and done this evil in thy sight:
That thou mightest be justified when thou speakest, and be clear when thou judgest.

Behold, I was shapen in iniquity;
And in sin did my mother conceive me.
Behold, thou desirest truth in the inward parts:
And in the hidden part thou shalt make me to know wisdom.
Purge me with hyssop, and I shall be clean:
Wash me, and I shall be whiter than snow.
Make me to hear joy and gladness;
That the bones which thou hast broken may rejoice.
Hide thy face from my sins,
And blot out all mine iniquities.
Create in me a clean heart, O God;
And renew a right spirit within me.
