1 Chronicles 20
1 Ref It happened, at the time of the return of the year, at the time when kings go out [to battle], that Joab led forth the army, and wasted the country of the children of Ammon, and came and besieged Rabbah. But David stayed at Jerusalem. Joab struck Rabbah, and overthrew it.
2 Ref David took the crown of their king from off his head, and found it to weigh a talent of gold, and there were precious stones in it; and it was set on David's head: and he brought forth the spoil of the city, exceeding much.
3 Ref He brought forth the people who were therein, and cut [them] with saws, and with harrows of iron, and with axes. Thus did David to all the cities of the children of Ammon. David and all the people returned to Jerusalem.
