Hinnom, valley, W and S of Jerusalem. Its ill repute in the Bible emanated from the worship there of foreign gods, including supposed child sacrifice to Molech at Tophet. In later Jewish literature it was called Ge-Hinnom [Heb.,=valley of Hinnom] and in the Greek of the New Testament, Gehenna. A place for burning refuse in later Israelite times, it provided imagery for a fiery Hell in the Books of Isaiah and the New Testament. It appears as Jahannam in the Qur'an.
