יֶהֱמ֣וּ יֶחְמְר֣וּ מֵימָ֑יו יִֽרְעֲשֽׁוּ־הָרִ֖ים בְּגַאֲוָת֣וֹ סֶֽלָה׃
מעגן ברומען, מעגן שױמען זײַנע װאַסערן, מעגן ציטערן די בערג פֿאַר זײַן הױכקײט. סֶלָה.
Rashi
His waters shall stir and be muddied Heb. יחמרו, they shall cast up mud, clay (חמר), and dirt as is their wont. Menachem (pp. 90f.), however, associated it with (Lam. 1:20), “my reins have shriveled (חמרמרו),” regrezeliront in Old French, have shriveled.
Rashi
mountains shall quake from His pride [The pride] of the Holy One, blessed be He, Who is mentioned in the beginning of the psalm (verse 2).
