1 Chronicles 20:1

At the time of the return of the year, at the time when kings go out, Joab led out 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.

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.

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.

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.

Now in the spring, at the time when kings go out to war, Joab went out at the head of the armed forces and made waste all the land of the Ammonites and put his men in position before Rabbah, shutting it in. But David was still at Jerusalem. And Joab took Rabbah and made it waste.
