Geenna, also called Gehinnom, is understood as the abode of the damned in the afterlife in Jewish and Christian Eschatology (it can thus be considered as hell). Named in the New Testament in Greek form (from the Hebrew Ge Hinnom, meaning “valley of Hinnom”). Geenna was originally a valley west and south of Jerusalem where children were burned as sacrifices to the warned god Moloch. This practice was practiced by the Israelites during the reigns of King Solomon in the 10th century B.C. and King Manasseh in the 7th century B.C. and continued until the Babylonian exile in the 6th century B.C.. Gehenna was later turned into a garbage collection center to discourage a reintroduction of such sacrifices.
The image of the burning of human beings provided the concept of “hellfire” to Jewish and Christian Eschatology. Mentioned several times in the New Testament (e.g., Matthew, Mark, Luke, and James) as a place where fire will destroy the wicked.
