2 Samuel 12:26-31
David wins Rabbah
26 At this time, Joab was attacking Rabbah, the Ammonite city. He had taken from the enemy the king's strong place in the city. 27 Joab sent men to take this message to David: ‘I have attacked Rabbah. Now I have taken the place that holds the city's water. 28 So you should bring the other soldiers of our army to make their camp here. Then you can attack the city and you can take it for us. If you do not do that, I will take the city myself. Then the city will have my name instead of yours.’
29 So David brought all the soldiers of the army together. He led them to Rabbah. They attacked the city and they won against it. 30 He took the crown off the Ammonite king's head. The crown was made of gold. It weighed 34 kilograms. There was a valuable jewel fixed on it. David's men then put the crown on David's head. David also took a lot of valuable things from the city. 31 He brought the people out from the city to do hard work for him. He made them cut wood with saws, and use iron tools and axes. He also made them work at the brick ovens. He did the same thing to the people of all the other Ammonite cities.
Then David and all his army returned to Jerusalem.
