The following spring, the time of year when kings go to war, Joab led the Israelite army in successful attacks against the towns and villages of the Ammonites. In the process they laid siege to the city of Rabbah and destroyed it. But David had stayed behind in Jerusalem.
When David arrived at Rabbah, he removed the crown from the king's head, and it was placed on David's own head. The crown was made of gold and set with gems, and it weighed about seventy-five pounds. David took a vast amount of plunder from the city.
