The same principle appears everywhere in the Bible: Pride has its roots in a feeling of wealth or accomplishment. "Wealth" does not necessarily mean money, although that is included. Remember Helel and his intelligence, beauty, and power. But there are other things like position, skill, natural ability, social status, knowledge, strength - even hair, clothing, a house, or an automobile. The list of things that can motivate this elevated feeling is virtually endless.
In the New Testament, pride is in the Greek, huperephanos, which means "to show oneself above." It does not imply one that others look up to, but one who stands on his own self-created pedestal. Psychologists tell us that pride is actually a mark of inner inferiority and uncertainty, and such people compensate by over-emphasizing and flaunting the qualities they think they possess that will cause others to think well of them.
This feeling of wealth or strength in a given area is highly relative because each person can set his own standard of comparison, regardless of his real accomplishments. Like the sluggard who in his conceit is wiser than seven men to render a reason (Proverbs 26:16), we are able to promote ourselves in areas that we think we are good in.
