Yirmeyah 51:63-64

Orthodox Jewish Bible

⁶³ And it shall be, when thou hast made an end of reading this sefer, that thou shalt bind an even (stone) to it, and cast it into the midst of Euphrates;

⁶⁴ And thou shalt say, Thus shall Bavel sink, and shall rise no more because of the ra’ah that I will bring upon her. Thus far are the Devarim of Yirmeyah.
