And they scoff at kings, And princes are a derision unto them; They deride every stronghold, For they heap up earth, and take it.
Rashi on Habakkuk
And they shall mock the kings shall mock them. Every expression of קַלָּסָה is an expression for the speech of those speaking about another; some [of these speeches] are for good, and some for bad - parledic in O.F.
Rashi on Habakkuk
a laughingstock like שְּׂחוֹק, laughter, like מִשְׁמָר, a watch, and מִסְתָּר, a hiding place.
Rashi on Habakkuk
He shall scoff at every fortress If his enemy is in a strong fortress, he scoffs at him.
