2 Samuel 12:24-31

Then David comforted Bathsheba, his wife, and slept with her. She became pregnant and gave birth to a son, and David named him Solomon. The LORD loved the child and sent word through Nathan the prophet that they should name him Jedidiah (which means “beloved of the LORD”), as the LORD had commanded. Meanwhile, Joab was fighting against Rabbah, the capital of Ammon, and he captured the royal fortifications. Joab sent messengers to tell David, “I have fought against Rabbah and captured its water supply. Now bring the rest of the army and capture the city. Otherwise, I will capture it and get credit for the victory.” So David gathered the rest of the army and went to Rabbah, and he fought against it and captured it. David removed the crown from the king’s head, and it was placed on his own head. The crown was made of gold and set with gems, and it weighed seventy-five pounds. David took a vast amount of plunder from the city. He also made slaves of the people of Rabbah and forced them to labor with saws, iron picks, and iron axes, and to work in the brick kilns. That is how he dealt with the people of all the Ammonite towns. Then David and all the army returned to Jerusalem.
