Bible Dictionary · D
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” (1 Chr 11:7). This was the name afterwards given to the castle and royal palace on Mount Zion, as distinguished from Jerusalem generally (1 Kgs 3:1; 1 Kgs 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, Luke 2:11), because it was David’s birth-place and early home (1 Sam 17:12).
