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.

It happened, at the time of the return of the year, at the time when kings go out [to battle], that Joab led forth the army, and wasted the country of the children of Ammon, and came and besieged Rabbah. But David stayed at Jerusalem. Joab struck Rabbah, and overthrew it.

And it came to pass, at the time of the return of the year, at the time when kings go out `to battle', that Joab led forth 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 overthrew it.

And it cometh to pass, at the time of the turn of the year -- at the time of the going out of the messengers -- that Joab leadeth out the force of the host, and destroyeth the land of the sons of Ammon, and cometh in and beseigeth Rabbah -- David is abiding in Jerusalem -- and Joab smiteth Rabbah, and breaketh it down.

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.
