Well, look at what that says. "... destroy both soul and body in hell." ???
Who can destroy both soul and body in hell?
God.
The antecedent to which realm, the earthly dirt body is destroyed, is....
That those in the natural material realm
CANNOT destroy the soul. Jesus makes that distinction, so as to highlight that the soul is accessible only to God, within his soul repository (Book of Life), just like a user account is within the system registry of the system administrator.
An anology is, that other user accounts (soul beings) cannot within the natural realm have administrator access to delete other user accounts, where each individual user is depicted as an IP address within the earthly realm WAN (wide area network), linking all hardware/firmware (body/brain) together, within this AI material universe simulated reality.
God can revoke a user account (soul) from acccessing his WAN (earthly material reality), therefore rendering the user account hell bound to the ether status, the user registry (soul repository) of the system administrator, where by default, the hardware/firmware (body/brain) is destroyed within the material reality, but that the soul is then relegated to the user account registry, until the system administrator decides to permanently wipe it out (jott it out) from his registry (book of life) and thereby as an anology condemn it to the Lake of Fire, which is the second death.
God is not actually destroying a material earthly body in Hell, but is destroying the soul in the Lake of Fire (metaphor) and this indirectly credits the body as well going there by the fact the soul access to the material realm has been revoked, pending final execution on death row, the second death.
Blessed and holy are those who share in the first resurrection. The second death has no power over them.
1st death is biological death, severing of the user account from the hardware/firmware.
2nd death is soul death, jotting out or wiping the user account from the soul registry (Book of Life) of the Creation/System Administrator who is God.
How is it that "both soul and body" can be destroyed in hell? How does the body get there?
As explained, the first tent, that is earthly body dies and returns to the dust where it came from, it doesn't materially go to an immaterial place called Hell. The detailed explanation is given above.
because you will not abandon me to the realm of the dead, nor will you let your faithful one see decay.
It is merely using a hyperbole of implying that if the material body, the first tent dies, then don't file me and forget about me in your user registry (soul repository), because I desire to be clothed. Again this phrase is pointing to the resurrection of the user account being upgraded to the second tent, the last Adam, within the second earth and second Heaven context. It just implies that God will not let us be naked souls within his soul repository, but will cloth us and upgrade our being to a higher realm of many rooms, that Jesus promised that he has prepared for us.
Apostle John in 1 John 3:2 said we don't know what that second tent will be. Paul alludes to it being a celestial body, for for the heavens, like the Lord from Heaven. We shall see him as he is in his Heavenly resurrected ten as our last Adam, so too will we be like him, what ever that second tent entails. It definitely is not the dirt body, because Paul states that the first tent must dissolve and something else must be raised to cloth the soul (user account, within the soul repository of God.
The realm of the dead below is all astir to meet you at your coming; it rouses the spirits of the departed to greet you— all those who were leaders in the world; it makes them rise from their thrones— all those who were kings over the nations.
Satan is depicted as finally joining those souls of the past kings and leaders he wielded, who are on second death row in the Lake of Fire, when he too joins them, when the Book of Condemned is opened at the Judgement of the Dead, the second death of those users accounts, inclusive of Satan who will permanently be erased from God's soul repository. It makes them rise from their thrones is a hyperbole as to say "what the heck", the same has become of you Satan.
