ציטירנדיקער פּירוש אויף תהילים 137:9

his sledgehammer Heb. כְּלִי מַפַּצוֹ, which smashes everything, as in (Ps. 137: 9): “and dash (וְנִפֵּץ) your infants.”

and this is all the fruit that is best for Me to remove his sin, if he makes all the altar stones of his high places, like crushed chalk-stones. מְנֻפָּצוֹת means crushed. Comp. (Ps. 137:9) “And crushes (וְנִפֵּץ) your babies.” Comp. (Jer. 13:14) “And I will crush them (וְנִפַּצְתִּים) one against the other.” גִּיר is a kind of dye.

and shattered me Heb. ויפצפצני, an expression of something being broken into many fragments with a hard blow, like (Jer. 13:14), “And I will dash them (ונפצתים), one against the other”; (Ps. 137:90), “and dash (ונפץ) your little ones against the rock. “

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.
