פּירוש אויף תהילים 2:9

You shall break them Heb. תרעם [like] תרוצצם.

Thou shalt break (הרעם) them with a rod of iron: – And so He says to me of all the nations that shall rise up against me, Thou shalt break them with a rod of iron.

You will break them (תְּרֹעֵם - tero'em): [This means] You will shatter them (teshabberem). The [letter] Ayin (ע) [the second root letter of ר-ע-ע] would properly have a dagesh (doubling dot) [in this verb stem], were it not for the fact that it is a guttural letter ("from the throat"). [This absence of an expected dagesh is] similar to [forms like] tesokhem (תְּשׂוֹכֵם) and tesovem (תְּסוֹבֵם), [where the middle root letter also lacks a dagesh].

with an iron rod That is the sword.

you shall shatter them Heb. תנפצם, you shall break them, and that is the expression of נפוץ throughout the Scriptures, a potsherd that is bro ken into fine pieces.
