JERUSALEM IS the center of the world in the Book of 1 Enoch. That echoes Ezekiel 5:5 and 38:12, where Jerusalem is “the center [literally, “navel”] of the earth.” 

This is a concept probably best known from Greek religion, where the oracle of Delphi was at the site of the omphalos, the stone that was supposedly substituted for Zeus by his mother Rhea because Kronos was eating their children as soon as they were born. The omphalos represented the connection between Earth and Heaven—in other words, it was the center (or navel) of the world. Ezekiel, whose prophecies were well known to the authors of 1 Enoch, wrote that it was the city God desired for His eternal dwelling place (Psalm 132:13–14) that was the true center of all things. 

The description of Jerusalem in 1 Enoch chapters 26 and 27 also includes a description of a “cursed valley,” which is a reference to the Valley of Hinnom, where children were sacrificed to Molech at the Tophet. Although we didn’t make it explicit in our discussion, this is the origin of the idea that equates the place of eternal punishment with Gehenna (Hebrew ge = “valley”; henna = "Hinnom”), found in Matthew 5:22, 29, and 30 (sometimes rendered “hell”). 

Enoch was also taken to the mountain of God where he was shown the Tree of Life and the Tree of the Knowledge of Good and Evil. The mountain of God is in the midst of “seven glorious mountains,” a sharp contrast to seven burning mountains described in 1 Enoch 18:13–16 and 21:3–6, which were angels being punished for transgressions. 

Finally, Enoch is transported to places that seem to be Petra and Arabia—interesting, since the only other locations that can be positively identified in 1 Enoch are Jerusalem and the areas around Mount Hermon.
