yes,,i do agree with you. i look at things at times(things mentioned in the text) i notice for instance in the n.t. books the writers do not mention the apostles by name i.e. "the one who cut off the soldiers ear",,(while peter was still alive) but after he was no longer living he is mentioned by name. that is they knew they would be in danger if they were not cautious.
the same brings up a strong argument as to the dating of Revelations that is he speaks of the temple as if it still was standing (when rev. was written). i studied for a while (online) about "the dating of the gospels",,which leads to dating the epistles ect. because of facts mentioned in them.
because of this at times on c.c. as i see the post about antichrist,and the 5 times used in johns writing i ask them "how can he go from fully understanding the antichrist" in the first books he wrote to not knowing in rev. where the angel tells him "i will show thee the mystery" that is he cannot go from knowing in the first books he wrote to not knowing in the last book he wrote.,,,,not to bring this up here tho only as an example i do realize there is the spirit of unbelief(denying the Messiah come in the flesh),and the ruler who will come in the last time (600 years,60 cubits,6 cubits) we looked at,,now these prophecies it seems are easy to combine.
so but back to the copper scroll i was looking at the things mentioned in the 64 statements as to who,what where,(as for a time frame),,,,,but as you point out "this issue is so complicated",,i was trying to find something more modern (closer to 1st century) mentioned in the copper scroll,i cannot unless the stater sheds some light?,,,even those who worked on it before us set it aside saying "unless any one of the things mentioned be found we cannot tell",,,
now in the 80's in Jordon cave 24 they found what they believe to be the the oil container used by the priest in the first temple/tabernacle? its not a gold vessel it is clay pottery. so they believed it to be one of the things listed in the copper scroll. it was also found along with several other metal books but i don't think it was the exact one mentioned in the copper scroll.
the Qumran priest? it seems to me also viewed the second temple as in a fallen state. it seems to me they were working with other priest who were in the temple. now it's unclear to me if they actually thought "king David" would raise from the grave and be again the king of Jerusalem but that from the time of the first temple they returned the tabernacle alter ect. to the mountain where Moses viewed the promised land. this they did in preparation for the Resurrection of "David"
here is a link
Vendyl Jones Research Institute (caution about information as always) but in it it mentions the "Mishnayot" and several other references from jubilees,Maccabees ect. they mention the same direction of thinking as it seems we find in the Qumran community but beggining at the 8th cen.bc,,,,and may well be what ended up being copied,,several times and the end product the "copper scroll",,,,now this link as the others i only "harvested historical information from" and the conclusions they drew some i do agree with but some not,,
but i do think this was the general path the Qumran peoples followed. i am christian,so i see the king resurrected on the third day,but it is quite confusing to see Qumran in this matter(to me),,it seems they did not see the king ascend to his throne they had prepared for so long.
its as though there were two frames of thought the scripture says "the tabernacle ascended from heaven to the earth among men",,,,,,,,,now one group of men ran out with maps and dug up the things and began to build,,,,,,but i saw Christ in his return,and his bride together one flesh,the father dwelling in "this temple" among man.,,,,two different things i think,,
