Jeremiah 25:11-12

And this whole land shall be a desolation, and an astonishment; and these nations shall serve the king of Babylon seventy years. And it shall come to pass, when seventy years are accomplished, that I will punish the king of Babylon, and that nation, saith Jehovah, for their iniquity, and the land of the Chaldeans; and I will make it desolate for ever.
