DESTRUCTION = OLETHROS
STRONGS DEFINITION
ruin, destroy, death
a) the destruction of the flesh, said of the external ills and troubles by which the lusts of the flesh are subdued and destroyed
The word ‘OLETHROS’ is properly interpreted as destruction.
He will punish those who do not know God and do not obey the gospel of our Lord Jesus. They will be punished with aionios destruction, that is, they will be shut out from the presence of the Lord and from the majesty of his power on the day he comes to be glorified in his holy people and marveled among all those who have believed.
The first word punish is “ekdikēsis” which is just concept of reap what is sown. The word second word punish is “dikē” which means to carry out the penalty of judicial decision.
This is true. Those who reign for 1000 years, reign with Christ in His glory. Yet, we know that those who were shut out of the kingdom for those 1000 years through their destruction (death), will be raised up last. The punishment is that 1000-year period in which the dead remain dead. However, in the end, we know they too will be raised in the second resurrection, we also know that the Sea, Hades, and Death must give up the dead within them. Knowing the meaning of AIONIOS, we understand that AIONIOS DESTRUCTION lasts a symbolic 1000 years.
So we read it again:
He will “ekdikēsis” (He will reward in accordance to their deeds) those who do not know God and do not obey the gospel of our Lord Jesus. They will be dikē (given the sentence of) aionios destruction [that is] they will be shut out [for a time] from the presence of the Lord and from the majesty of his power on the day he comes to be glorified in his holy people and marveled among all those who have believed.
