Hell is a old english way of avoiding persecution by the Church in the translation days. it was translated from four very different words.
Sheol = Grave
Hades = Grave
Tartaroo = the abyss = Black nothingness
Gehenna = the valley of Slaughter
If you took The Gospel to far remote island dwellers isolated from the rest of the world, who also had their own specific language, and they had only one word in their language which partially covered the concept of a place after death for the dead, would you be inclined to use it? That's what Paul and other disciples did with the Konine Greek. Tartaroo and hades were Greek terms for a place for the dead. And the pagan Greeks had all sorts of beliefs and traditions attached to those terms. So how did Apostle Paul teach in the Greek to overcome the pagan's usage of such terms? By examples to show the difference.
When Jesus said in Matt.10:28 to not fear those who can kill the body but not the soul, to understand that doesn't require we have a specific word for where the soul goes after flesh death. The common sense of the Message is enough to know that some type of place or state for the soul after flesh death must exist. It is automatically inferred within His statement there. But our Lord Jesus did not leave us guessing, for He told the malefactor crucified with Him that he would be with Him in Paradise that day. So that idea of Paradise is a specific label, but still from the Greek language manuscripts of the Book of Luke. 1 Peter 3:19 also gives us a bit more information on a place for the dead after flesh death, revealing there is a place in the heavenly after flesh death where some souls go to and are put in a heavenly prison. Same idea of a heavenly prison is described with the idea of Satan being locked in his pit prison in the heavenly.
So what does all this New Testament information about a place in the heavenly after flesh death do to all the Old Testament usages for Hebrew sheowl, etc.? Just because other words like in Hebrew are used, does that really change... the whole concept of a heavenly prison for dead souls after they died? If Christ was able to preach The Gospel to the "spirits in prison" who were sometime disobedient back to Noah's days according to Peter, how does that shed new light upon souls of the dead in Old Testament times? In other words, the idea of a holding place in the heavenly for the wicked did not just change... between Old and New Covenant periods. The same kind of place that exists now per the New Testament examples is the same place that existed back in Old Testament times too.
