"Wrath is cruel and anger a torrent, but who is able to stand before jealousy?" (Prov. 27:4) "For wrath kills a foolish man, and envy slays a simple one." (Job 5:2)

There is an old fable about an eagle who boasted of how he could out-fly all others. One day another eagle came along who could out-fly him. This made the proud eagle very jealous. One day he saw a hunter walking along with his bow and arrow and said to him, "I want you to shoot that eagle." The hunter replied, "I would if only I had some feathers to put on my arrow to make it shoot straighter and farther." The eagle pulled some feathers out of its wings and gave them to the hunter. When the arrow was shot, it did not reach the rival eagle because he was too far away. The envious eagle pulled out more feathers. This continued until he lost so many feathers he couldn't fly, and then the hunter turned and shot him.

The moral of the story is: "If you are jealous of another, you only hurt yourself."
