Truths of God were not the same as the Biblical Patriarch’s understanding of their surroundings. Nonetheless, there was a symbiosis between YHVH and Israel through YHVH’s ‘metalogue’.
God might say “forever” concerning HIS statutes …yet, there was no example of specific ***relatable*** ‘Time-mapping’, only conceptualizing of ‘referred continuance’ by the tools given to the primitive sense, not a lesser ‘sense’. Furthered, humankind has a ‘lifetime’, a ‘durative’ notion to the Cosmos by which humankind is cosmologically – agriculturally ‘related’ by not fully conceptualized or mentally ‘relatable’ as ‘comprehensible’. Therefore, “forever” is a toss at the unseen as the unseen is conceptualized. (“Forever”: Hebrew: Olam: Genesis 9:12; Ecclesiastes 12:5; Isaiah 26:4; Psalm 145:13; etc. { all such usages allude to a ‘duration’ of non-accounting-rather, an era or aeon}). This “non-accounting” does not mean that the concept of ‘accountable’ is dismissed, it is not that at all.
So, “forever” is an idea that is beyond the scope of one person’s lifetime. “Forever” was ‘participated’ in hierarchical festivities, agricultural observances, and various religious observances in order to ‘partake’ of the mask of eternity. “Representation” becomes the practical approach.
