1 Chronicles 11:4-9

4David and all Israel marched to Jerusalem (that is, Jebus); the Jebusites who inhabited the land were there.

5The inhabitants of Jebus said to David, “You will never get in here.” Yet David did capture the stronghold of Zion, that is, the city of David.

6David said, “Whoever is the first to kill a Jebusite will become chief commander.” Joab son of Zeruiah went up first, so he became the chief.

7Then David took up residence in the stronghold; therefore, it was called the city of David.

8He built up the city all the way around, from the supporting terraces to the surrounding parts, and Joab restored the rest of the city.

9David steadily grew more powerful, and the Lord of Armies was with him.
