וְנִפַּצְתִּים֩ אִ֨ישׁ אֶל־אָחִ֜יו וְהָאָב֧וֹת וְהַבָּנִ֛ים יַחְדָּ֖ו נְאֻם־יְהוָ֑ה לֹֽא־אֶחְמ֧וֹל וְלֹֽא־אָח֛וּס וְלֹ֥א אֲרַחֵ֖ם מֵהַשְׁחִיתָֽם׃ (ס)
Puis je les briserai les uns contre les autres, les pères et les fils ensemble, dit l’Éternel; ni pitié, ni compassion, ni miséricorde, ne m’empêcheront de les détruire."
Rashi on Jeremiah
And I will dash them one against the other I will dash one against the other until they break into small pieces. Cf (Psalms 2:9) “Like a potter’s vessel shall you shatter them (תנפצם)” (ibid. 137: 9). “And dash ונפץ your babes”; and so is every expression of נפוץ in Scripture.
Rashi on Jeremiah
and the fathers and the sons I will dash one against the other.
