Jeremiah 25:11-14

25:11 This whole area will become a desolate wasteland. These nations will be subject to the king of Babylon for seventy years.’

25:12 “‘But when the seventy years are over, I will punish the king of Babylon and his nation for their sins. I will make the land of Babylon an everlasting ruin. I, the Lord, affirm it! 25:13 I will bring on that land everything that I said I would. I will bring on it everything that is written in this book. I will bring on it everything that Jeremiah has prophesied against all the nations. 25:14 For many nations and great kings will make slaves of the king of Babylon and his nation too. I will repay them for all they have done!’”
