is there anywhere in the Bible in which hell is reffered to as eternal torture?
Kind of, maybe.
In the Greek we get words and expressions like
aionion and
tous aionos ton aionon. These are often translated as "everlasting"/"eternal" and "forever and ever" respectively. More literally tous aionos ton aionon translates as "the ages of the ages", while
aionion is the adjective form of the Greek word aion, which as one might guess already means "age". Aionon probably, in a more strict sense, means something like "enduring" or "age-enduring", with the sense of something of an age, or enduring of an age, with the age being indefinite. Since it is indefinite, then if the "age" is unending then it means somewhat implicitly that it is everlasting.
As such, if the realities of hell (whatever they might be) are of unending endurance, then we could say they are "eternal".
But I've here really only touched upon the "eternal" aspect. The other is "torture". The implication of the word "torture", at least in the popular notion of hell, is that God sentences people to ceaseless tortures, and thus it is an eternal torture external, and given from God. That is how some Christians have perceived hell in history. I don't think it's particularly biblical though, nor is it the most representative of historic Christian thought.
One of the chief problems about talking about hell biblically is that the Bible says almost nothing on the subject. An objective reading of Scripture reveals that there are different sorts of ideas, and descriptions being used to describe both the present and future state of the wicked; but at no point do we get anything resembling a discrete picture. We have Jesus in the Gospels using the common Jewish idea that the place of the dead (She'ol or Hades) is split between the place of the righteous dead (Paradise) and the place of the wicked dead (Gehenna); the thing is the Jewish view was hardly all that dogmatic, and to the extent we have a picture of popular Jewish eschatology Hades/She'ol was a stop-gap, an interim, a waiting place until Resurrection and Judgment. Jewish views of the time, as now, remain diverse. Perhaps the second most important place people look for hell language is the Lake of Fire mentioned in St. John's Apocalypse (Revelation), of course given the very nature of the Revelation as apocalyptic and figurative language is attempting to take what is apocalyptic as literal just doesn't work. In the Apocalypse we read that even death and hades are cast into the lake, which should at least offer us pause as we contemplate what is being said.
It shouldn't be entirely shocking, then, to discover that at no point in the two thousand years of Christian history has there ever been anything resembling a definite view of "hell". There has, instead, always been a great deal of diversity. There are a myriad of views on the subject in Christianity, without any one being authoritative or definite. There is no
de facto orthodox view of Hell.
