Hell is the grave...
Hell’ is an Anglo-Saxon word for grave ( a hell-grond was a graveyard) and in the Old Testament is usually translated from an original Hebrew word meaning pit or grave; or in the New Testament from an original Greek word meaning grave or hell, or another Greek word used for the place where refuse was incinerated and completely destroyed outside Jerusalem.
Ecclesiastes 9:4-6, 10
For to him that is joined to all the living there is hope: for a living dog is better than a dead lion. For the living know that they shall die: but the dead know not any thing, neither have they any more a reward; for the memory of them is forgotten. Also their love, and their hatred, and their envy, is now perished; neither have they any more a portion for ever in any thing that is done under the sun... ...Whatsoever thy hand findeth to do, do it with thy might; for there is no work, nor device, nor knowledge, nor wisdom, in the grave, whither thou goest.
Put not your trust in princes, nor in the son of man, in whom there is no help. His breath goeth forth, he returneth to his earth; in that very day his thoughts perish.
Nevertheless man being in honour abideth not: he is like the beasts that perish. This their way is their folly: yet their posterity approve their sayings. Selah. Like sheep they are laid in the grave; death shall feed on them; and the upright shall have dominion over them in the morning; and their beauty shall consume in the grave from their dwelling.
