Hell is a place with many sub-sections to it.  In all, hell has 5 compartments.  Hell can be spoken of as a whole entity, but usually the Bible specifies where in hell it is talking about.  This can be proven when you go back to the Greek scriptures.  There are 5 Greek words used when the original scriptures are talking about hell, but the English versions of the Bible usually only translate it as one word: "hell".  So, although the translation isn't wrong, per se, the translation could be better, as I see it.  Let's begin.

The first section of hell is called Tartarus, which comes from the Greek "ταρταρώσος" (2 Peter 2:4).  This place is a prison for fallen angels who sinned before the flood of Noah.  No human beings or demons ever go there anymore.  Greek literature (not biblical, but not to be thrown out as complete lies) also describes this place as being where the Titans and other powerful creatures make their dwelling.

The second section is called paradise, the Greek is "παραδείσω" (Luke 23:43), and this is the place where righteous dead stayed before Jesus' first coming.  They were held captive here by Satan because Jesus had not conquered death yet.  After He died on the cross and opened the way for gentiles, conquering death, Jesus went to paradise and took all the souls from there with Him when He ascended to Heaven (Ephesians 4:8).

Hades/Hell is the third part of hell.  In Greek, it is "’άδες" (Matthew 16:18).  The Hebrew calls it sheol-hades which is almost literally translated as "the unseen world of hell".  This can be related to what you already believe to be hell, as it is a place reserved for nothing but torment.  The wicked dead have always gone here.  After the 1000 year reign of Christ on Earth (Revelation 20:4) these souls will be reunited with their unglorified bodies and cast into the lake of fire for all eternity along with Satan and the rest of the fallen angels.

The Abyss/Bottomless Pit would be the fourth part of Hell (Romans 10:7).  The Greek is "’άβυσσος".  This is the abode of demons and some angelic beings.  The 200,000,000 demons released in Revelation come from this Pit.  No human ever has or ever will go here.  The hebrew equivalent is "abaddon" and is translated into English as "destruction". 

The final word translated as hell, unless otherwise specifically noted, is the Lake of Fire, or "λίμνεν τοù πύρος" (Revelation 21:8).  This is the eternal hell and perdition of fallen angels and wicked humans.  Also referred to as Gehenna (γέεννα).  It must be taken as a literal lake of fire because that is how it is described in the bible, and that is what the Greek refers to it as well as the English.  There is nothing symbolic about it.

For those of you that have looked up the verses and still don't believe that Paradise is a part of hell, then please allow me to explain.  In Ephesians 4:9 Jesus went to preach to the people in paradise, this is stated as fact in the bible.  Jesus went to paradise (Luke 23:43).  Also, hell is in the bowels of the earth according to Ezekiel 31:14 ("nether parts of the earth".)  Now, if you read the verse Matthew 12:40, Jesus went to the bowels of the earth, everything falls in place.  To lay it out nice and neat, follow below:

Jesus went to paradise to save lost souls, after dying on the cross;

Hell is in the nether parts of the earth;

Jesus went to the bowels of the earth.

Paradise is in the bowels of the earth, thus making it a part of hell!
