Strongs only mentions hell because the KJV does and Strong's is based on the KJV not the other way around. "Hell" was never mentioned in any manuscript before the KJV because it is an English word taken from Norse mythology (the English were made up of Danes and Jutes(Vikings) and Angles and had absorbed much of their language and mythology).
IMO, Hell was an invention with no root in the scriptures at all.www.hell-is-a-myth.webs.comHow Sheol Became Hell
Sheol >Hades >Inferno >Hell
Hebrew >Greek >Latin >English
Hades came from the Greeks and was primarily a place of darkness. The word morphed from "Haides" which was originally Aionis and Aides (from aidos meaning "unseen"). Tartarus was below Hades and was a special prison for titans and involved torment.
The similarities are striking enough to make you wonder if these mythologies(egyptain, greek, roman) did not originate from stories passed down through the ages from the children of Noah re-called from pre-flood times(notably Gen 6).
Inferno came from the Romans and incorporated the idea of flames and torment. It was ruled by Pluto who was also god of time and earth and wealth. Dante took "inferno" and popularized the idea of the devil tormenting souls in worse and worse ways as you went lower and lower into it.
Hel came from the Norsemen, it was ruled by a female god Hela and was the place for the departed dead who were not warrior heroes, who went to Valhalla. "Go to Hel" was a Norse curse meaning, DIE
The English (KJV)took all three and rolled them up into one and translated Sheol (which originally meant "the unknown"and came to mean "the grave" among the Hebrews) into Hell, bringing with it all the mythological baggage of Hades, Inferno and Hel.
Hades (play /ˈheɪdiːz/; from Greek ᾍδης (older form Ἀϝίδης), Hadēs, originally Ἅιδης, Haidēs or Άΐδης, Aidēs (Doric Ἀΐδας Aidas), meaning "the unseen") was the ancient Greek god of the underworld. Thayer
