[5]1 Peter 1:23
(23) For you have been born again, not of perishable seed, but of imperishable, [ ̓́αφθαρτος/aphthartos] through the living and enduring word of God.
1 Peter 1:25
(25) but the word of the Lord endures forever.[αἰών/aion] " And this is the word that was preached to you.

[10]1 John 2:17
(17) The world and its desires pass away, but whoever does the will of God lives forever. [αἰών/aion]

[13]Luke 1:33
(33) And he shall reign over the house of Jacob for ever; [αιωνας/aionas] and of his kingdom there shall be no end.[τελος/τελος]
In this verse “aionios” is paired with “without end.” “aionios” cannot be paired with “without end” if it means only “ages” a finite period. “Aionios” by definition here means eternal.
[14]Revelation 14:11
(11) And the smoke of their torment ascendeth up for ever and ever:[εις αιωνας αιωνων/eis aionas aionas] and they have no rest day nor night, who worship the beast and his image, and whosoever receiveth the mark of his name.
In this verse “aionas aionon torment” is paired with “no rest day or night.” If “aionas, aionon” means “a finite period” at some time they would rest, “Aionas, aionon” by definition here means “forever and forever.”
[15]John 10:28
