Zion, Eretz Yisrael (The Land of Israel) and Jerusalem are mentioned frequently in ancient Jewish texts: the Bible, the Prophetic Books, the Talmud, and the ​Siddur (Jewish prayerbook). The archeological evidence for Jewish presence in The Land of Israel is abundant. While it has evolved over two millennia, the basic structure and core cont​ent of the ​Siddur and the special prayers for home and synagogue were codified and have been set for worship since the early rabbinic period, about the 6t​h​ century of the common era.
