The Story fo David: Sin and Consequences

All of the chapters from David’s assuming power until his putting down Sheva Ben Bichri’s revolt, which constitutes most of what is written about David, seem to have been David’s sin with Bat Sheva and how he dealt with his punishment.  After that point, the text seems to rewind and give a summary of the other relevant events in David’s kingship in a single chapter (21.)  It seems that the most important thing the Prophets wanted us to know about David was how he dealt with his sin.
