Hi SAT,
thank you for sharing your questions.
No. 2, in my opinion, doesn't exist.
There is nothing that God destroys that he couldn't restore, as I see it.
Jesus was also destroyed at the cross, in my opinion.
in this case if you have questions as to which death that is, it is best to type that passage into Biblehub interlinear, to seek out all the occurances of the word.
In this case, you just happened to choose the wrong translation.
It is like this:
Luke 12:5 Interlinear: but I will show to you, whom ye may fear; Fear him who, after the killing, is having authority to cast to the gehenna; yes, I say to you, Fear ye Him.
So the word "destroy" doesn't figure in that passage.
However, speaking from own memory, in Psalms there is a passage that does say "destroy" indeed.
So if you want to know if this destruction ois eternal, seek out the exact word used for "destroy", click on it at Biblehub interliniear and find in which context this word is used at other occurances.
If I remember well, this word was used fairly often in circumstances in which the destruction was not final.
But find out yourself!
Thomas
P.S.: I would choose another translation. KJV is 98% right as I see it.
They sometimes make mistakes, as I see it. For instance they said virgin birth when in fact Bible only mentions that a virgin became pregnant (which is not the same, of course) - I'm speaking from memory here.
So if you want to be 100% sure... take Biblehub Interlinear version.
