Psa 51:1 To the chief Musician, A Psalm of David, when Nathan the prophet came unto him, after he had gone in to Bathsheba. Have mercy upon me, O God, according to thy lovingkindness: according unto the multitude of thy tender mercies blot out my transgressions.
Psa 51:2 Wash me throughly from mine iniquity, and cleanse me from my sin.
Psa 51:3 For I acknowledge my transgressions: and my sin is ever before me.
Psa 51:4 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.
Psa 51:5 Behold, I was shapen in iniquity; and in sin did my mother conceive me.
It seems there is a difference between all 3.
Can someone break down all 3? A little confused.
