(60486 to 39486 ((AD 1406 is the mirror of 1406 BC, which is the year Israel entered the Promised Land after coming out of Egypt 40-years earlier in 1446 BC.
Also, AD 586 is the mirror of 586 BC, the fall of Jerusalem.)(Thus, beginning either with 390 or 430 years from the entry into Egypt, both alternating patterns yield the same end-dates of AD 586 and AD 1406, which are the mirrors of the exile from the Promised Land and the entry into the Promised Land.)The pattern is close enough so as to be striking even if it were out one year; however, the difference can be largely accounted for anyway.
For example, the number of years that elapse between 10 BC and AD 10 are 19 years, not 20.) Significantly, Jesus not only was named on the 8th day, the number that symbolizes "a new beginning", but His very name numerically also adds up to 888. 13:8 with the next verse.) It is obvious, then, why the 8th day from his birth is the timing of the mirror and not the first day. This does not mean that an equal event of significance occurs in its AD counterpart. Because, in order for these awesome patterns to exist Jesus had to be born on the very year and day and hour that he was.It simply means that in order for the following patterns to occur, God had already predetermined before Christ that Christ's birth would commence the new era for counting years, even as it is today. The mirror occurs at the traditional birth date of AD 1, Dec.The following is deduced: The Sumerian chronology uses a 360-day/year within Precession of the Equinoxes (2580 years).An extra leap-month is added when system viewed forward or backward.Note that Ezekiel laid siege symbolically to Jerusalem for 390 days (and 430 days).
