2 Samuel 12:26-31

²⁶Now Joab fought against Rabbah of the sons of Ammon, and captured the royal city. ²⁷Then Joab sent messengers to David and said, “I have fought against Rabbah, I have even captured the city of waters. ²⁸Now then, gather the rest of the people and camp opposite the city and capture it, or I will capture the city myself and it will be named after me.” ²⁹So David gathered all the people and went to Rabbah, and he fought against it and captured it. ³⁰Then he took the crown of their king from his head; and its weight was a talent of gold, and it had a precious stone; and it was placed on David’s head. And he brought out the plunder of the city in great amounts. ³¹He also brought out the people who were in it, and put some to work at saws, iron picks, and iron axes, and made others serve at the brick works. And he did the same to all the cities of the sons of Ammon. Then David and all the people returned to Jerusalem.
