תהילים קלז:ג פירוש: רש״י

and our tormentors mirth Heb. ותוללינו, kinds of musical instruments that they hang up. This is how Menachem interpreted it (p. 184): וְתוֹלָלֵינוּ שמחה, and our musical instruments of joy. וְתוֹלָלֵינוּ can also be interpreted as: our enemies who would scorn and mock and joke with us, an expression of (102: 9): “those who scorn me (מהוללי) swear by me.”
