In the spring when kings march out to war, Joab led the army and destroyed the Ammonites’ land. He came to Rabbah and besieged it, but David remained in Jerusalem. Joab attacked Rabbah and demolished it.Then David took the crown from the head of their king, and it was placed on David’s head. He found that the crown weighed 75 pounds of gold, and there was a precious stone in it. In addition, David took away a large quantity of plunder from the city.He brought out the people who were in it and put them to work with saws, iron picks, and axes. David did the same to all the Ammonite cities. Then he and all his troops returned to Jerusalem.
( Only Og king of Bashan was left of the remnant of the Rephaim. His bed was made of iron. Isn’t it in Rabbah of the Ammonites? It is 13 feet six inches long and six feet wide by a standard measure.)
David told the messenger,“ Say this to Joab:‘ Don’t let this matter upset you because the sword devours all alike. Intensify your fight against the city and demolish it.’ Encourage him.”
