1 Chronicles 11:6-8

Young's Literal Translation

⁶ And David saith, `Whoever smiteth the Jebusite first doth become head and prince;' and go up first doth Joab son of Zeruiah and becometh head.

⁷ And David dwelleth in the fortress, therefore they have called it, `City of David;'

⁸ and he buildeth the city round about, from Millo, and unto the circumference, and Joab restoreth the rest of the city.
