Commentaries:
Zophar connects wickedness with hypocrisy, and then connects both of them with pride. Where does pride appear here? It is in the word excellency—"through their own self-perceived excellency." Many modern translations, seeing what Zophar intended, translate "excellency" as "haughtiness."
The hypocrite is deceived into ignoring realities the meek and humble person might quickly recognize. A deceived person does not know he is deceived, or he would not be deceived. Pride is so powerful that it can deceive quite intelligent people. It is not a matter of intelligence but one of the right kind of knowledge and the willingness to submit to it.
