1 Chronicles 20:1-2

1In the spring, Joab led the Israelite army out to fight. That was the time of year when kings go out to fight battles. Joab and his army attacked the land of the Ammonites and he won against them. He put his soldiers around Rabbah city so that they could attack it. But David had stayed in Jerusalem. Joab attacked Rabbah and he destroyed its buildings.

2When David came, 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.
