'Rivalry' in the Bible

For I am afraid that perhaps when I come I may find you not to be as I wish, and that you may find me not as you wish—that perhaps there may be strife, jealousy, angry tempers, disputes, slander, gossip, arrogance and disorder;

Some, it is true, are [actually] preaching Christ out of envy and rivalry [toward me—for no better reason than a competitive spirit or misguided ambition], but others out of goodwill and a loyal spirit [toward me].

But if you have bitter jealousy and selfish ambition in your hearts, do not be arrogant, and [as a result] be in defiance of the truth.

For where jealousy and selfish ambition exist, there is disorder [unrest, rebellion] and every evil thing and morally degrading practice.
