This drawing shows the City of David on the Eastern Hill of Jerusalem.
King David captured the city of the Jebusites (2 Samuel 5.9) and since that time it was called the City of David. The Jebusite fortress was destroyed and covered over with a stepped stone structure that may have served as a foundation for David’s Palace/Fortress that stood higher up the hill. The Jebusite city walls remained intact and were an integral part of the defences of the City of David.
This drawing also shows a fortified area to the east of the City of David with a large tower. This tower was built in the Jebusite period and continued to be used until the time of Hezekiah.
