Gehenna, (/ɡɪˈhɛnə/; Hebrew: גיא בן הינום‎‎ Ancient Greek: γέεννα), from the Hebrew Gehinnom (Rabbinical: גהנום/גהנם), is a small valley in Jerusalem and the Jewish and Christian analogue of hell. The terms are 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.
