Jeremiah 25:11–12

11 And this whole land shall be a desolation, and an astonishment; and these nations shall serve the king of Babylon seventy years. 12 And it shall come to pass, when seventy years are accomplished, that I will punisha the king of Babylon, and that nation, saith the LORD, for their iniquity, and the land of the Chaldeans, and will make it perpetual desolations.
