1 Chronicles 11:6-8

Amplified Bible, Classic Edition

⁶ And David said, Whoever smites the Jebusites first shall be chief and commander. Joab son of Zeruiah [David’s half sister] went up first, and so he was made chief.

⁷ David dwelt in the stronghold; so it was called the City of David.

⁸ He built the city from the Millo [a fortification] on around; and Joab repaired and revived the rest of the [old Jebusite] city.
