SEVENTY YEARS...

“Therefore thus says the LORD of hosts: ‘Because you have not heard My words....
Moreover I will take from them the voice of mirth and the voice of gladness, the voice of the bridegroom and the voice of the bride, the sound of the millstones and the light of the lamp. And this whole land shall be a desolation and an astonishment, and these nations shall serve the king of Babylon seventy years.

For thus says the LORD: After seventy years are completed at Babylon, I will visit you and perform My good word toward you, and cause you to return to this place. For I know the thoughts that I think toward you, says the LORD, thoughts of peace and not of evil, to give you a future and a hope. Then you will call upon Me and go and pray to Me, and I will listen to you.
Jeremiah25:8,11; 29:10-12

In the first year of Darius the son of Ahasuerus, of the lineage of the Medes, who was made king over the realm of the Chaldeans—in the first year of his reign I, Daniel, understood by the books the number of the years specified by the word of the LORD through Jeremiah the prophet, that He would accomplish seventy years in the desolations of Jerusalem. Daniel 9:1-2

Gabriel, whom I had seen in the vision....
and said, “O Daniel, I have now come forth to give you skill to understand.
“Seventy weeks are determined
For your people and for your holy city,
To finish the transgression, To make an end of sins, To make reconciliation for iniquity, To bring in everlasting righteousness,
To seal up vision and prophecy, And to anoint the Most Holy.
