Modern scholars argue that Jews branched out of the Canaanite peoples and culture through the development of a distinct monolatrous – and later monotheistic – religion centered on El/Yahweh, These foundational events, straddling the dawn of the 1st millennium BCE, assumed central symbolic importance for the Jewish people. The sobriquet of holy city ("עיר הקודש", transliterated "'ir haqodesh") was probably attached to Jerusalem in post-exilic times. The holiness of Jerusalem in Christianity, conserved in the Septuagint which Christians adopted as their own authority, was reinforced by the New Testament account of Jesus's crucifixion there. In Sunni Islam, Jerusalem is the third-holiest city, after Mecca and Medina.

Outside the Old City stands the Garden Tomb.
