If Sheol/Hades/Hell is a place, it must be a metaphysical place - a place that does not exist in the physical realm, similar to Heaven. -- Nathan.
I continue to stress that sheol/hades is NOT a literal place, and so it needs to be understood that nobody has ever gone there literally. It's merely an IMAGINARY (metaphorical) place that serves the purpose of expressing the helpless state of humans after they die. For example, mournful Jacob (thinking that his son was dead) greived because Joseph's soul (the life that was once his before death) had become prisoner to an imaginary place he called "sheol". Jacob had faith that his son would come back to life in the resurrection. When finally Joseph is restored to life it can be figuratively said that he (his life/soul) was released from the bonds of sheol.
