Meanwhile Joab fought against Rabbah1 of the Ammonites and captured the royal citadel.
Joab then sent messengers to David, saying, "I have fought against Rabbah and taken its water supply.
Now muster the rest of the troops and besiege the city and capture it. Otherwise I will take the city, and it will be named after me."
So David mustered the entire army and went to Rabbah, and attacked and captured it.
He took the crown2 from the head of their kinga--its weight was a talentb of gold, and it was set with precious stones--and it was placed on David's head. He took a great quantity of plunder from the city
and brought out the people who were there, consigning them to labor with saws and with iron picks and axes, and he made them work at brickmaking.c He did this to all the Ammonite3 towns. Then David and his entire army returned to Jerusalem.
