Jeremiah 51:63-64

And as soon as you finish reading this scroll, you shall tie a stone to it and throw it into the middle of the Euphrates. Then say, ‘In the same way Babylon will sink down and not rise because of the disaster that I will bring on her; and the Babylonians will become [hopelessly] exhausted.’ ” Thus the words of Jeremiah are completed. [Rev 18:21]
