Thematic Bible: Ammonites defeated and tortured

Now Joab fought against Rabbah of the children of Ammon, and took the royal city. Joab sent messengers to David, and said, "I have fought against Rabbah. Yes, I have taken the city of waters. Now therefore gather the rest of the people together, and encamp against the city, and take it; lest I take the city, and it be called after my name." read more.
David gathered all the people together, and went to Rabbah, and fought against it, and took it. He took the crown of their king from off his head; and its weight was a talent of gold, and [in it were] precious stones; and it was set on David's head. He brought forth the spoil of the city, exceeding much. He brought forth the people who were therein, and put them under saws, and under iron picks, and under axes of iron, and made them pass through the brick kiln: and he did so to all the cities of the children of Ammon. David and all the people returned to Jerusalem.
