We start our study of the next Great Jubilee Cycle of 490 years from the Dedication of the Temple to the Decree to restore Jerusalem, which initiates the 490 years of Daniel's 70 Weeks (Dan 9:24-25). We will prove this time consists of 560 years minus 70 unreckoned years of Servitude to Babylon, making 490 years.
This time includes the time of the Divided Kingdom, which adds to its complexity, because we are given the reigns of both the kings of Judah and of Israel, as well as many synchronisms connecting them.
The Messiah is descended from the kings of Judah, so the primary chronology is provided by Judah, but this must be fine-tuned by harmonising it with the chronology of Israel's kings.
Moreover, the way these 2 kingdoms measured the reigns of their kings differed. For example, we show that one used Accession Years, while the other used the Non-Accession Year System.
