'City of David' in the Bible

And the inhabitants of Jebus said to David, Thou shalt not come in hither. But David took the stronghold of Zion, which is the city of David.

And David dwelt in the stronghold; therefore they called it the city of David.

And David brought not the ark home unto himself into the city of David, but he carried it aside into the house of Obed-Edom the Gittite.

And he made him houses in the city of David, and prepared a place for the ark of God, and spread a tent for it.

And it came to pass as the ark of the covenant of Jehovah came to the city of David, that Michal the daughter of Saul looked through a window, and saw king David dancing and playing; and she despised him in her heart.
