Jesus believed in and warned people about a place called hell. The word he used was “gehenna”, which is normally translated in our English Bibles as “hell”.
In Old Testament times the valley south-west of Jerusalem was called Ge Hinnom and it was the city’s rubbish dump. It was a notorious valley that was previously used as a place of child-sacrifice to Molech* the detestable God of the Ammonites. Molech’s image was believed to have been a hollow brazen figure, with the head of an ox, and outstretched human arms. The figure was heated red hot by a fire from within and the babies placed in its arms to be slowly burned, while to prevent the parents from hearing the dying cries, the sacrificing priests beat drums.
