RE: Hell is a human concept of something we don’t understand, and the bible clearly says it’s temporary because it is thrown into the lake of fire, which is also a concept.
“Hades” is the Greek word for the realm of the dead. In the Greek Septuagint, it replaces the Hebrew word “Sheol”.
There’s not a lot of description of Hades within the main canon - chiefly the teaching of Jesus in Luke 16 - but generally it is considered the holding place for the souls of the dead until the final judgement.
It is sometimes thought to be divided into “compartments” of sorts: e.g. a place of torment and a place of comfort (the bosom of Abraham). This is somewhat apparent in Luke 16 and 2 Peter 2:4 mentions the angels bound in Tartarus: the Greek name for the place of torment.
You’ll see in Revelation that Hades is always accompanied by Death (esp. see Revelation 6:8 where they are together personified). Death is thought to claim the material portion of a person and Hades the immaterial portion.
Whatever it is, the Lake of Fire supercedes Hades. Once Hades gives up its dead for the final judgement it is no longer needed and is sent to destruction along with those whose names were not in the book of life. Keep in mind that earlier Death and Hades were personified, so it makes sense in the apocolyptic setting that they could be sent to the same “place” as other persons.
Thank you for going to that trouble clarifying it. I agree with everything in that post.
