1 Chronicles 20:1
And it came to pass, that after the year was expired, at the time that kings go out to battle, Joab led forth the power of the army, and wasted the country of the children of Ammon, and came and besieged Rabbah. But David tarried at Jerusalem. And Joab smote Rabbah, and destroyed it.
This verse stands within the larger block of 1 Chronicles 4–26, which traces the work of David at length. It belongs specifically to the record of David's work, taking its place among the accounts of what he did and directed. That record presents both his virtues and his mistakes, holding together his faithfulness and his failures. The books of Samuel contain a related account of the same history, and that parallel is to be compared with this verse in order to understand it fully.
