In the Bible, Jerusalem is defined as lying within territory allocated to the tribe of Benjamin though occupied by Jebusites. David is said to have conquered these in the Siege of Jebus, and transferred his capital from Hebron to Jerusalem which then became the capital of a united Kingdom of Israel, and one of its several religious centres. The choice was perhaps dictated by the fact that Jerusalem did not form part of Israel's tribal system, and was thus suited to serve as the centre of its confederation. Opinion is divided over whether the so-called Large Stone Structure and the nearby Stepped Stone Structure may be identified with King David's palace, or dates to a later period.
