KJV
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.
BSB
In the spring, at the time when kings march out to war, Joab led out the army and ravaged the land of the Ammonites. He came to Rabbah and besieged it, but David remained in Jerusalem. And Joab attacked Rabbah and demolished it.
