1 Chronicles 11:4-9

David and all the Israelites went to the city of Jerusalem. At that time Jerusalem was called Jebus, and the people living there were named Jebusites. They said to David, “You can’t get inside our city.” But David did take the city of Jerusalem with its strong walls, and it became the City of David. David had said, “The person who leads the attack against the Jebusites will become the commander over all my army.” Joab son of Zeruiah led the attack, so he became the commander of the army. Then David made his home in the strong, walled city, which is why it was named the City of David. David rebuilt the city, beginning where the land was filled in and going to the wall that was around the city. Joab repaired the other parts of the city. David became stronger and stronger, and the LORD All-Powerful was with him.
