2 Samuel 12:26-30

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.
