Commentaries:
The subject here is God, and He scorns the scornful. Scorn, a contempt or disdain, is a fruit that pride produces in a person, and it is usually shown toward someone thought to be an inferior. A human being will tend to avoid the person who he deems unworthy, or he will immediately reject or ridicule the unworthy person's opinions. What is the effect of this? It breaks people into cliques. Scorn divides and separates.
