1 Chronicles 11:5-7

Revised Geneva Translation

⁵ And the inhabitants of Jebus said to David, “You shall not come in here.” Nevertheless, David took the tower of Zion, which is the City of David.

⁶ And David said, “Whoever strikes the Jebusites first shall be the chief and captain.” So Joab, the son of Zeruiah, went up first and was captain.

⁷ And David dwelt in the tower. Therefore, they called it the City of David.
