Most interesting catch on dates, and as you said a special decree was granted by Artaxerxes I to Nehemiah
(444-445BC). This is the ONLY decree recorded in the Bible that
gave the Jews permission to "restore Jerusalem and rebuild its
walls," and since Scripture relates to Scripture, we should start
counting time from that biblical decree. Just as Daniel predicted,
Nehemiah had a terrible time wall-building. The people living
around Jerusalem tried to stop him every way they could (Neh
4:1-23). They even tried to get the government to come down on
Messiah's date of crucifiction, and If, He was crucified in 30 or late as 33 AD. He didn't die for Himself, but for the
sins of the whole world (1Jo 2:2), but are those 69 weeks 69
sevens of years? If so, then we have 69 x 7 or 483 Hebrew years.
The Lord usually spoke to His prophets in a language they
could understand. Daniel was a Jew, probably of the royal family
(2Ki 20:18), and the Jews had their own 360-day Levitical year.
Since our history is recorded in solar years of 365.24 days, we
need to convert 483 Hebrew years to solar years:
483 x .9857 = 476 solar years.
The whole book of Nehemiah is about events following the Artaxerxes I decree.
Furthermore, the events recorded in Nehemiah perfectly match Daniel's prophecy of them.
The dating of this decree is firm at 445-444BC.
2 From I Maccabees and the Book of Jubilees (circa 150BC), the Jews of intertestamental times generally considered a month to have 30 days, and a year to have12 months. So a year of 360 days was probably the calendar with which Daniel was familiar. That is why a year of 360 days should be used when calculating O.T. prophecies.
Artaxerxes' decree, 444BC + 476 years = 32AD, the cross
right to the year? (give or takeaway zero year add 1 minus 1)
what about those six points that were supposed to be fulfilled during these 70 weeks? All but one were fulfilled at the cross. Did not Jesus (1) finish transgression eternally, (2) make an end of sin, (3) make reconciliation for iniquity, (4) bring in everlasting righteousness, and (6) anoint the Most holy with His own precious blood. I believe so.
Point (5), however, was left out: "Seal up vision and
prophecy." This is where those peculiar 7 weeks and 62 weeks
7 x 7 Hebrew years = 48.3 Solar years. 444BC - 48.3 is
395.7BC, Malachi written.
Malachi was inspired to write the last book of the Old
Testament in about 396BC. The Scripture to the Jews was
complete, and no more was written until the New Testament era!
So Old Testament vision and prophecy were indeed "sealed up."
something to consider is all.
Is there still a "second fulfillment"? I'll be seeking to find, and trust all who read will too!
Peace and Come Lord Jesus come!
