Reference for Jeremiah 51:64

וְאָמַרְתָּ֗ כָּ֠כָה תִּשְׁקַ֨ע בָּבֶ֤ל וְלֹֽא־תָקוּם֙ מִפְּנֵ֣י הָרָעָ֗ה אֲשֶׁ֧ר אָנֹכִ֛י מֵבִ֥יא עָלֶ֖יהָ וְיָעֵ֑פוּ עַד־הֵ֖נָּה דִּבְרֵ֥י יִרְמְיָֽהוּ׃ (ס)

and thou shalt say: Thus shall Babylon sink, and shall not rise again because of the evil that I will bring upon her; and they shall be weary.’ Thus far are the words of Jeremiah.
