1 Chronicles 20:1-3 - The Capture Of Rabbah
1 Later the next spring, at the time that kings go out to fight, Joab led out the army, ravaged the territory of the Ammonites, and then went out and attacked Rabbah, while David remained behind in Jerusalem. Joab besieged Rabbah and conquered it. 2 David confiscated the crown of their king from his head, and found that its weight was a talent in gold. A precious stone had been set in it, and it was placed on David's head. He also confiscated a great amount of war booty that had been plundered from the city, 3 brought back the people who had lived in it, and put them to conscripted labor with saws, iron picks, and axes. David did this to every Ammonite city, and then David and his entire army returned to Jerusalem.
