Jeremiah 25: 11: And this whole land shall be a desolation, and an astonishment; and these nations shall serve the king of Babylon seventy years.
The Jews were captives in Babylon for 70 years because they rejected the message of the prophet Jeremiah.
The Holy Spirit descended in Armenia during the 19th century and began a revival that spread into Russia. This great revival would later be called “Pentecost”.
The Russian government responded by killing many Christians; the LORD judged Russia for this bloodshed by enslaving the nation to Communism for 70 years, from the 1917 Bolshevik Revolution to 1987 (when Communism began to collapse).
The Holy Spirit then moved to the west coast of America in 1906 and began the Azusa Street Revival.
