David, City of

(1.) David took from the Jebusites the fortress of Mount Zion. He "dwelt in the fort, and called it the city of David" (1Chr 11:7). This was the name afterwards given to the castle and royal palace on Mount Zion, as distinguished from Jerusalem generally (1Kings 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" (Luke 2:4; 2:11), because it was David's birth-place and early home (1Sam 17:12 ).
