(1.) David took from the Jebusites the fortress of Mount Zion. He "dwelt in the fort, and called it the city of David" (1Ch 11:7). This was the name afterwards given to the castle and royal palace on Mount Zion, as distinguished from Jerusalem generally (1Ki 3:1; 8:1), It was on the south-west side of Jerusalem, opposite the temple mount, with which it was connected by a bridge over the Tyropoeon valley.
(2) Bethlehem is called the "city of David" (Lu 2:4,11), because it was David's birth-place and early home (1Sa 17:12).
