1 Chronicles 20:1-3

1In the spring, the time when kings go out to battle, Joab led the army ⌞to war⌟. They destroyed the Ammonites and came to Rabbah to attack it, while David stayed in Jerusalem. Joab defeated Rabbah and tore it down.

2He took the gold crown from the head of Rabbah’s king and put it on David’s head. (The crown was found to weigh 75 pounds, and in it was a precious stone.) David also took a lot of goods from the city.

3He brought out the troops who were there and put them to work with saws, hoes, and axes. He did the same to all the Ammonite cities. Then David and all the troops returned to Jerusalem.
