In the spring of the year, at the time when kings normally conduct wars, David sent out Joab with his officers and the entire Israelite army. They defeated the Ammonites and besieged Rabbah. But David stayed behind in Jerusalem.

So Joab fought against Rabbah of the Ammonites and captured the royal city.

Joab then sent messengers to David, saying, "I have fought against Rabbah and have captured the water supply of the city.

So David assembled all the army and went to Rabbah and fought against it and captured it.

When David came to Mahanaim, Shobi the son of Nahash from Rabbah of the Ammonites, Makir the son of Ammiel from Lo Debar, and Barzillai the Gileadite from Rogelim
