Jeremiah 29:10

For thus saith the Lord, That after seventy years be accomplished at Babylon, counting from the time the first exiles were taken to Babylon with their King Jeconiah, I will visit you, turn to them in merciful kindness, and perform My good word toward you, cause His promise to them to be fulfilled, in causing you to return to this place, to Jerusalem and Judah, the home of their fathers.
