Forever and ever
"Note it in a book that it may be for the time to come forever and ever that this is a rebellious people."
No book lasts forever. Neither does Israel's rebellion last forever. Jeremiah 24:7
Jeremiah 7:7 and 25:5
The promise was that the land was individually given to them until they died, and as a nation was given to them until the earth shall be burned up and God creates a new earth. 2Peter 3:10-13.
THE AGES IN THE SCRIPTURES – VLADIMIR GELESNOFF
"Words are inadequate to describe the harm which has resulted from confounding the ages with eternity.
The Greek and Hebrew terms rendered 'forever and ever,' 'eternal,' 'everlasting' never refer to endlessness; but to a series of terminable periods know as age-times. These ages are periods in which God carries on remedial work, but they have a conclusion and pass away when the purpose to be accomplished in them has been realized. The ages are never synonymous with endlessness but always distinct therefrom.
That the words translated 'forever and ever' are associated with the hereafter of both believer and unbeliever is true; but in the case of both it is limited to the span of the ages, and has not the remotest reference to the final state of either. Therefore the dogmas of endless agony and endless sin rest on purely imaginary premises and are without the slightest shred of biblical support."
EONIAN - EVERLASTING OR AGE-LASTING – GRACE H. TODD
"That the expression 'the eons of the eons' (forever and ever, KJV) cannot mean an endless successions of eons is clearly revealed by comparing Rev. 11:15 with 1Cor. 15:24-28. In Rev. 11:15 our Lord is said to reign 'for the eons of the eons' but in 1Cor. 15 His reign is said to end. He does not reign 'for ever and ever' though He does reign for the eons of the eons."
