יִמָּאֲס֣וּ כְמוֹ־מַ֭יִם יִתְהַלְּכוּ־לָ֑מוֹ יִדְרֹ֥ךְ חצו [חִ֝צָּ֗יו] כְּמ֣וֹ יִתְמֹלָֽלוּ׃
Sie sollen zergehen wie Wasser, das zerfließt; schießt er seine Pfeile ab, so seien sie, wie wenn sie zerbröckelten.
Rashi on Psalms
Let them be rejected by themselves, that they will be rejected in their own eyes from worry, and as [if] in water let them walk. Similar to this is (Ezek. 7:17): “and all knees will go [as in] water,” from tears.
Rashi on Psalms
He will aim His arrows i.e., the Holy One, blessed be He, so that they will be cut off. יתמֹללוּ is soyent preciz, let them be cut off.
