It’s not referring to hell, it’s referring to a prison, the same word is used to refer to the bottomless pit where Satan is thrown in Rev. 20:7 -
“7 And when the thousand years are expired, Satan shall be loosed out of his prison,”
Then, after his “little season”, we see him cast into hell in verse 10:
“10 And the devil that deceived them was cast into the lake of fire and brimstone, where the beast and the false prophet are, and shall be tormented day and night for ever and ever.”
So, yes, Jesus did go to a third place that is neither heaven nor hell, he went to the prison, or bottomless pit, that is reserved for disobedient angels.
I will pray for you.
