1 Chronicles 11:6-9

11:6 David said, “Whoever attacks the Jebusites first will become commanding general!” So Joab son of Zeruiah attacked first and became commander. 11:7 David lived in the fortress; for this reason it is called the City of David. 11:8 He built up the city around it, from the terrace to the surrounding walls; Joab restored the rest of the city. 11:9 David’s power steadily grew, for the Lord who commands armies was with him.
