Kommentar zu Tehillim 76:6

became mad Heb. אשתוללו, like השתוללוּ. As (II Chron. 20:35): “And afterwards, Jehoshaphat the king of Judah joined (אתחבר) Ahaziah the king of Israel,” like התחבר. [The word] אשתוללוּ is derived from (Job 12:17): “He leads counselors away with madness (שולל).” It is an expression of error and tranquility, as madmen err, and the “tav” falls into the middle of the word in the reflexive, as in every word beginning with “shin.”

slumbered in their sleep They Heb. נמו. They fell into a deep sleep, an expression of תנוּמה slumber.

and none...found their hands and their strength when You came to punish them.
