It is in eg Mark:
Mark 9:43 ... rather than having two hands, to go to hell, into the fire that shall never be quenched.
So I don't think you can say 'not burning forever' was the general view.
There the word is
shamad, 'be destroyed'.
or
shamad; or to eternal fire.
ὁ θάνατος ὁ δεύτερός 'death, the second one' yup.
It's not unlikely that Ep. Hebrews is a pseudepigraph, but that aside, the phrase is καταργήσῃ ... τὸν διάβολον '[that] he might destroy' the devil, not 'destroyed'.
There, for the reasons above, we must differ.
At that point in Ecclesiastes he's saying that the dead are dead, end of story. Later he considers what becomes of the 'breath', the spirit (without making it clear what).
Wow, it seems as if you have given much thought in your ^ above^ reply.
Right, at Ecclesiastes 12:7 Solomon considers the spirit ( it ).
Thus, one's life's spirit (it) is a neuter "it" just as it is at Numbers 11:17,25.
As far as ' breath ' please notice Psalms 104:29 because when 'breath ' is taken away one dies....
Dies just as Adam died and 'returns' to the dust - Genesis 3:19
I find in the Christian 'Greek' Scripture of Mark 9:43 is the word: Gehenna.
King James used the English word hell in place of the word Gehenna found in verse 43.
I am wondering where you got the word shamad at verse 43.
' fire the inextinguishable ' is: Gehenna .
Gehenna was a garbage pit outside of Jerusalem where things were destroyed. Not kept burning forever.
So, Gehenna is a fitting word for: destruction - Psalms 92:7
Thus, the symbolic ' lake of fire ' is ' fire the inextinguishable '
The definition of the lake of fire is defined as 'second death' according to Revelation 20:13-14.
In death there is No pain ( Psalms 115:17; Psalms 146:4; Ecclesiastes 9:5; Isaiah 38:18; John 11:11-14 )
Thus, the wicked which are ' destroyed forever ' are considered as being in ' second death ' (No resurrection).
Sinner Satan ends up in ' second death ' (Revelation 21:8)
Through Jesus' death, Jesus might make Satan ineffective - Hebrews 2:14 B, and this is a sure thing since sinner Satan ends up in 'second death'.
Sinner Satan knows he has a short or limited amount of time as per Revelation 12:12 B; Psalms 37:9-11.
Jesus was made manifest in that Jesus might destroy the works of the devil as per 1 John 3:8 B; John 8:44.
A foremost work of the devil is ' death ' thus Jesus brings to nothing ' enemy death ' - 1 Corinthians 15:26.
Brings an end to death for those who will stand fast in righteousness toward God and Jesus.
