Hell is considered by some people as a place where the soul suffers after death. The concept of hell is widely distributed in religious beliefs all over the world, such as Buddhism, Hinduism, some factions of Judaism and Christianity today, Islam and so on.
Fundamentalist Jews, on the other hand, don't recognize the existence of hell and think it is a heretical concept influenced by pagan ideas. Hell refers to the place where the dead are detained and punished, which can be said to be the prison and execution ground of the underworld.
Extended data:
Lucifer, the former vice king of heaven, God's right-hand man, an archangel with six wings of light, led one-third of the angels of heaven to launch a rebel war in the south of the original heaven (the highest place in heaven, also called Crystal Heaven) for various reasons, and was taken to Chuangshi Mountain to fall into the sky after failure.
The concept of seven demons in hell was invented by later generations, mostly from the personal imagination of Japanese comics and domestic fantasy writers, which does not conform to the Christian Bible.
The etymology of Satan is the verb "confrontation", which has been used in the Bible to refer to the devil who confuses mankind (the snake and the red dragon in the Garden of Eden).
