Well, you need two datelines. 84 could be one, and you've made a plausible argument for 84 doctrinally and datewise, but you need a second which is doctrinally-consistent. Elision looks okay.
84 is DECREE MADE meter, established by Moses in
Psalm 90. So that fits, too. Isaiah split up the 84 into two 42 bookends for the Decree of Messiah First to Last David in
Isaiah 53 (52:13-14=42 syllables, and 53:12=42 syllables).
Instead of 44 years you'd want 84 years after. If we say 30 rather than 31 AD which 84 years aft would produce, then 30+84=114, would be 115 if -53+84; the Kitos war ref is interesting. We need to know more about it. Paul benchmarks 114 in Ephesians
when satirizing Trajan, for he dies at the end of having increased Rome to its largest extent, only to be undone by his heir Hadrian (satire using the eta in thelematos three times, each with same meaning of an emperor death which is in vain).
If you split the 84 like Isaiah did, then 31+42 is 73, which could tie to Temple Destruction date, as the Lord would then be age 73 using Paul's A.D. counting style. That's what John does in his letters: Christ born 4103 from Adam's Fall therefore 4176. Which is, 40 years after Isaiah 53's endpoint (37AD is when Christ was supposed to die, had Israel accepted Him).
Most interesting, is the 44 versus 40. The latter is well known number of judgment, and the extra 4 has so much meaning re the flaw in Varro's accounting which ended up causing our own BC/AD accounting flaw, plus a cute ref to the constantly-recurring 3.5 hanging chad. I gotta think about it more, though.
So the meter looks quite plausible, with doctrinal fit. We still need the second dateline, to better know.
So that second dateline, in your workup, is
63, same as Psalm 90, seven more than 56. Clever. So let's apply the test:
30+63 is 93, 31+63 more like it, 94 as Lord's Age, when Trib supposed to start. Hence the extra seven, being made up so the Trib can begin on time anyway. But either way, since you're in your 94th year when age 93. So 90-91 AD, three years after John penned Revelation. Meaning? Mid-Trib schedule, when Temple abominated.
What about 63 years prior? That would be 33BC, possibly 32BC, Augustus' rise to power, though he himself dated it from Actium which was 31. But then we've the 4-year variance, which wasn't favored UNTIL Augustus (Varro's calendar only became law under Claudius). Given the 40/44 play, I have to think something deliberate's going on here, but what? Not sure.
The other two, ending with 91 as 21+70 is very Mosaic Psalm 90, idea of using 70 as a 490. Maybe that's why Paul also structured Eph1:3-14 using 434, to play on both Matt24 and Daniel 9 at the same time? Same style as Isaiah 53? Intriguing.
Pattern: 84+63+21+70+84 (so bookended, playing on Isaiah 53, DOUBLING his bookending)
+ 133 (again playing on the candlestick meter in Isaiah, 52;13-53:2, then also 53:9-12, each 133 syllables),
+105 (prominent in Paul but I'm not sure all of what it means, seems to make up for the extra 7 from when Mill was supposed to begin at His Age 98).
Verse 4 using 21, number of years Jacob was under Laban -- is the meter of GROWTH. So GROWTH is forecast under pressure. That Growth occurs best under pressure. As, with Jacob. Idea of indenture.
70 of course, is the meter of mass voting by believers to grow, in 490+70+490=1050, the foundational civilization unit which Moses used in Gen 1 meter. Interesting that it's used for
verse 5, to describe both the Church Age (which after all hadn't yet begun and might still not have) -- as well as the Trib -- which is also a voting. Equating the two, and of course there's 7*70, 490.
Not seeing the palindrome which is another characteristic, yet bookending is clear (test of meter being deliberate, not coincidental). AND 63+21=84.
Peter played on 84 for his dateline meter, too.
Wait, we do have a palindrome:
verses 7-9 are of opposite meter compared to
1-2. Mirrored. So it's deliberate.
Verses 10-14 at 133, just like Isaiah and
Daniel used it, but is the Lord also piggybacking? In Daniel 9:7 where the piggybacking started, the 133 differential is marked by SUMMATION of Israel's sins whether 'near or far'. So too, verses 10-14 seem a summation again of worldwide scope. What about Psalm 90 and Isaiah 53? In the latter, the 133s are used for Decree balanced by history, respectively. Psalm 90:7 ends cumulatively at 133, and that's the verse on how we end our lives angry with God (accusing Him of our own anger). But of course Ephesians 1 wasn't written yet, so no ties there.
Now the final paragraph, re the Trib itself,
verses 15-18. I see the 105 a lot, seems to be 98 (Lord's Age when Mill was supposed to begin) +7, as if all history is 7 years later than scheduled, pre-Church. Trouble is, I haven't found yet WHEN that extra seven began. It might have been with Jacob, for remember only a total of 14 years working was supposed to occur. Or it might have occurred with David living to age 77 not 70, when he retired (pity scholars don't read 1Kings 6:1 properly). So 105 comes to mean a TIME MAKEUP FINISHED value.
It's interesting that 105x12=1260. That's another way to see the syllables are deliberately metered, for those in the Trib will need the mnemonic when to start the countdown that Revelation 11 reveals (1221.75 then 75 then Abomination set up, with 1260 being the midpoint, remember SOLAR year accounting means 365.25x7=2556.75 days in 7 years).
So the meter total is 560, VOTE COMPLETION! Wow, I've been looking for that; we have the 560 (v.19) and 1050 (v.31) in Geneis 1 meter, the 490's used in Psalm 90 and Isaiah 53 and Paul, but I'd not seen a 560 yet in other OT or NT. I don't see any need to change your elision assumptions, either. You seem to be onto something here! Maybe a whole timeline for eternity from His Time forward, playing on Daniel 9:24's
suntelw? It's so similar to Moses in Psalm 90 and Isaiah 53, I wonder...
