" The actual word “hell” is used roughly twelve times in the New Testament, almost exclusively by Jesus himself. The Greek word that gets translated as “hell” in English is the word “Gehenna.” Ge means “valley,” and henna means “Hinnom.” Gehenna, the Valley of Hinnom, was an actual valley on the south and west side of the city of Jerusalem. Gehenna, in Jesus’s day, was the city dump. "
