1 Chronicles 20:2-3

2Then David took the crown from the head of their king.1 It was found to weigh a talent of gold2 and was set with precious stones, and it was placed on David’s head. And David took a great amount of plunder from the city.

3David brought out the people who were there and put them to work3 with saws, iron picks, and axes. And he did the same to all the Ammonite cities. Then David and all his troops returned to Jerusalem.
