1 Chronicles 11:6-8

Contemporary English Version

⁶ David had told his troops, “The first soldier to kill a Jebusite will become my army commander.” And since Joab son of Zeruiah attacked first, he became commander.

⁷ Later, David moved to the fortress—that's why it's called the City of David. ⁸ He had the city rebuilt, starting at the landfill on the east side.^[a] Meanwhile, Joab supervised the repairs to the rest of the city.
