1 Chronicles 11:4-9
David and his men attack Jerusalem
4 David and the whole Israelite army marched to attack Jerusalem. At that time, the city was called Jebus. The people who lived there were called Jebusites. 5 The Jebusites said to David, ‘You will never get into our city.’ But David did get in and he took Zion, the city's strong place. It is now called the City of David.
6 David had said to his soldiers, ‘The man who attacks the Jebusites first will become the captain of my army.’ Zeruiah's son Joab attacked first. So he became the captain of the army.
7 David went to live in the strong place of the city. So people called it ‘The City of David’. 8 David built more houses all around it, from the edge of the hill to the city's walls. Joab built up again the other buildings in the city. 9 David became more and more powerful because the Lord Almighty was with him.
