The name is found in 2 Samuel (5:7), one of the books of the Hebrew Bible dated to before or close to the mid-6th century BCE. It originally referred to a specific hill in Jerusalem (Mount Zion), located to the south of Mount Moriah (the Temple Mount). According to the narrative of 2 Samuel 5, Mount Zion held the Jebusite fortress of the same name that was conquered by David and was renamed the City of David.
