אֵ֤יךְ נִגְדַּע֙ וַיִּשָּׁבֵ֔ר פַּטִּ֖ישׁ כָּל־הָאָ֑רֶץ אֵ֣יךְ הָיְתָ֧ה לְשַׁמָּ֛ה בָּבֶ֖ל בַּגּוֹיִֽם׃
How is the hammer of the whole earth Cut asunder and broken! How is Babylon become A desolation among the nations!
Rashi on Jeremiah
the hammer of the whole earth which would shatter and crush everyone.
