Thomas Aquinas, on Ps 54:9

“I waited for him that hath saved me from pusillanimity of spirit, and a storm.”

“"Because I have seen iniquity." Here he describes their malice. And first he describes the common malice of the world. Second, the malice of a certain principal person among them. He describes the common malice of the multitude first in general. Second, in particular, at "Day and night." In a multitude there is a twofold disorder. One on the part of the rulers. The other on the part of the people. For a city is well ordered when the rulers govern justly and the people obey; otherwise it is not well disposed. And such a city is the world, in which neither do the rulers govern justly nor does the people obey. But the city of God is well ordered. In the city of the world, therefore, "I have seen iniquity and strife." I saw iniquity on the part of the rulers and judges. Is. 1: "Your assemblies are wicked." Likewise, I saw strife against the prelates. Is. 41: "Your people are like mud that is trampled upon."”
