'City of David' in the Bible

And the inhabitants of Jebus say to David, 'Thou dost not come in hither;' and David captureth the fortress of Zion -- it is the city of David.

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

And David hath not turned aside the ark unto himself, unto the city of David, and turneth it aside unto the house of Obed-Edom the Gittite.

And he maketh for himself houses in the city of David, and prepareth a place for the ark of God, and stretcheth out for it a tent.

and it cometh to pass, the ark of the covenant of Jehovah is entering in unto the city of David, and Michal daughter of Saul is looking through the window, and seeth king David dancing and playing, and despiseth him in her heart.
