What does the Bible say about David's sin in Psalm 51?

In Psalm 51, David acknowledges his transgressions and the depth of his sin, stating, 'Against thee, thee only, have I sinned and done this evil in thy sight.' This acknowledgment conveys the comprehensive nature of his sinfulness, not just in his actions but as part of his very nature, as made clear when he states he was 'shapen in iniquity.' The psalm reveals David's understanding that true repentance involves recognizing the gravity of sin and its consequences, as well as the need for divine grace.
