Gehenna

Gehenna (/ɡɪˈhɛnə/; Ancient Greek: γέεννα), from the Hebrew Gehinnom (Rabbinical: גהנום/גהנם), are terms derived from a place outside ancient Jerusalem known in the Hebrew Bible as the Valley of the Son of Hinnom (Hebrew: גֵיא בֶן־הִנֹּם or גיא בן-הינום, Gai Ben-Hinnom). The Valley of Hinnom is the modern name for the valley surrounding Jerusalem's Old City, including Mount Zion, from the west and south. It meets and merges with the Kidron Valley, the other principal valley around the Old City, near the southeastern corner of the city.
