Psalms 51:1-7 KJV
Have mercy upon me, O God, according to thy lovingkindness: according unto the multitude of thy tender mercies blot out my transgressions.
Wash me thoroughly 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.
