2 Samuel 12:26-30

26Meanwhile, Joab fought against Rabbah of the Ammonites and captured the royal fortress. 27Then Joab sent messengers to David to say, “I have fought against Rabbah and have captured the water supply of the city.1 28Now, therefore, assemble the rest of the troops, lay siege to the city, and capture it. Otherwise I will capture the city, and it will be named after me.”

29So David assembled all the troops and went to Rabbah; and he fought against it and captured it. 30Then he took the crown from the head of their king.2 It weighed a talent of gold3 and was set with precious stones, and it was placed on David’s head. And David took a great amount of plunder from the city.
