Daniel 12:2 is a good example of what I was saying about olam.
The word translated everlasting in Dan 12:2 is olam(or owlam,or olammim). This word is used 450 times in the OT. Here are a couple examples that clearly do not mean “everlasting”.
…then take an awl and push it through his earlobe into the door, and he will become your servant** for life**(olam). Deut 15:17 NIV
…Then thou shalt take an aul, and thrust it through his ear unto the door, and he shall be thy servant for ever(olam). KJV
Clearly he will not be someones slave forever. He will be a slave for the time that remains in his life, as the NIV correctly translates it.
The Nephilim were on the earth in those days–and also afterward–when the sons of God went to the daughters of humans and had children by them. They were the heroes of old(olam), men of renown. Gen 6:4
Here olam clearly does not mean everlasting or forever. It means in the far distant past.
from an unused word
long duration, antiquity, futurity(NAS Exhaustive Concordance)
olam: long duration, antiquity, futurity
Original Word: עוֹלָם
Part of Speech: Noun Masculine
Phonetic Spelling: (o-lawm’)
Short Definition: forever (Strong’s Concordance)
Strong favors the KJV , but clearly states the same thing the NAS does in the definition, because it has to, because in so many places olam cannot be translated forever, or everlasting. It means long duration, forwards or backwards.
In places where olam means something akin to everlasting it is doubled “olam olam” which really means ages of ages, which is as close to forever Hebrew ever got.
“Blessed are You, O LORD God of Israel our father, forever and ever(olam wead olam). 1 Chron 29:10 NAS
olam is determined by its context and the subject is describing, a lifetime(indeterminate period), a long, long way back in time(an indeterminate period), a long way into the future(an indeterminate period)
Remember, Lord, your great mercy and love, for they are from of old(olam) Ps 25:6 NIV
“The LORD is merciful and gracious, slow to anger, and plenteous in mercy. He will not always chide: neither will he keep his anger for ever”(olam). Ps 103:8,9
He will not be angry for a long long time. He will not chide for a long, long time. He will not punish the wicked forever.
"As for man, his days are as grass: as a flower of the field, so he flourisheth.
16For the wind passeth over it, and it is gone; and the place thereof shall know it no more.
17But the mercy of the LORD is from everlasting to everlasting(olam wead me olam>>>olam from to olam) upon them that fear him, and his righteousness unto children’s children" Psalm 103:15-16 KJV
I have examined all 450 occurrences of olam, it is an indefinte period appropriate to the subject, and imo as regards the wicked, it is until “every knee bows, whether in heaven or on earth or under the earth, and every tongue confess that Jesus Christ is Lord to the glory of God the Father”
In all wisdom and insight 9 He made known to us the mystery of His will, according to His kind intention which He purposed in Him 10 with a view to an administration suitable to the fullness(pleroma fulness, completion) of the times, that is,** the summing up of all things in Christ**, things in the heavens and things on the earth. Eph 1
When the “times” are fulfilled, when time is complete, everything will have been “gathered into one in Christ Jesus”(KJV)
There is an excellent article on this here tentmaker.org/books/time/Time_6.html and further chapters show the relationship between olam and aionios
