Contradiction with 2 Samuel 11:1
While both passages describe the same event – the siege of Rabbah – 2 Samuel 11:1 states that David remained in Jerusalem, whereas further text details David's involvement in the situation that followed, which 1 Chronicles 20:1 does not.
2 Samuel 11:1: And it came to pass, after the year was expired, at the time when kings go forth [to battle], that David sent Joab, and his servants with him, and all Israel; and they destroyed the children of Ammon, and besieged Rabbah. But David tarried still at Jerusalem. [after...: Heb. at the return of the year, or, in the spring]
Paradox #1
The verse in question mentions a war season, but it does not directly mention Bathsheba or David's wrongdoing with her, which is described in 2 Samuel 11. This omission can seem inconsistent or conflicting because both passages discuss events related to King David, yet they focus on different aspects or details of that time.
