1 Chronicles 11:5-7

Revised Standard Version

⁵ The inhabitants of Jebus said to David, “You will not come in here.” Nevertheless David took the stronghold of Zion, that is, the city of David. ⁶ David said, “Whoever shall smite the Jeb′usites first shall be chief and commander.” And Jo′ab the son of Zeru′iah went up first, so he became chief. ⁷ And David dwelt in the stronghold; therefore it was called the city of David.
